How Blood Tests Spot Changes in your Blood Before You Have Symptoms

Many doctors recommend blood tests to spot early symptoms of health problems. A single blood test can reveal crucial information about your health and wellness.

Most of us have had blood tests – but few people know what doctors are looking for on a blood test.

Today, we’re explaining some of the basics behind a blood test. Keep reading to discover how blood tests spot changes in your blood before you have symptoms.

How Blood Tests Work

During a blood test, a specialist takes a small sample of blood from your body. A lab analyzes your blood, then delivers results to your doctor.

Most doctors recommend blood tests as part of a routine checkup. Doctors can check some symptoms during a routine physical – like your blood pressure.

However, a blood test goes “behind the scenes” to discover more information about your physical health and wellness.

Depending on the type of test, you may need to fast for 8 to 12 hours before the test (say, for a blood glucose test). With many blood tests, however, you are not required to fast.

Blood tests are quick and easy. A technician will draw blood from a vein in your arm using a needle. Or, some blood tests take a finger prick.

What Do Blood Tests Show?

A traditional blood test can reveal:

  • How well your organs are working, including your kidneys, liver thyroid, and heart
  • Early symptoms of diseases like cancer, diabetes, anemia, coronary heart disease, or HIV/AIDS
  • Risk factors for heart disease based on the components in your blood
  • Whether or not your medications are working
  • How well your blood clots

Types of Blood Tests

Some of the most common types of blood tests include:

  • Complete blood count (CBC) blood tests
  • Blood chemistry tests
  • Blood enzyme tests
  • Blood tests for heart disease risk

Blood tests check different things. A CBC blood test, for example, is one of the most common types of tests and is frequently recommended as part of a routine checkup. A CBD blood test can detect blood diseases, anemia, infections, clotting, or cancers in your blood.

Types of Information Revealed on a Blood Test

Most of us know how blood tests work. However, few of us actually understand what’s on a blood test report. Your doctor analyzes the results, then explains them to you – but you may not know what each component on your blood test means.

Here are some of the components included on a typical blood test:

White and Red Blood Cell Count: Red blood cells carry oxygen from your lungs to the rest of your body. White blood cells influence your immune system. If you have abnormal red or white blood cell counts, it could be a sign of infection, blood cancer, or an immune disorder.

Platelets: Your blood clots because of platelets. Platelets are fragments of blood cells that stick together, sealing cuts and preventing excessive bleeding. A blood test could tell you if platelet levels are too low, which could be a sign of a bleeding disorder. Or, you could have too many platelets, which is a thrombotic disorder that leads to too much clotting.

Hemoglobin: Hemoglobin is a protein in red blood cells that carries oxygen. If you have excessive hemoglobin, you could have anemia, sickle cell anemia, or other blood disorders.

Blood Glucose: If your doctor required you to fast before a blood test, the doctor may have wanted to check your fasting blood glucose levels. Glucose is the type of sugar your body uses for energy. If you have abnormal blood glucose levels, it’s a sign of diabetes. Some blood glucose tests do not require fasting.

Calcium and Electrolyte Levels: A blood test can reveal abnormal levels of calcium and electrolytes, which could be a sign of disease. If you have excessive levels of calcium, sodium, potassium, or chloride in your blood, then it could be a sign of dehydration, kidney disorder, high blood pressure, malnutrition, or other issues.

Organ Function: Blood tests reveal important information about organ function. If a doctor requests a blood test for your kidneys, then the blood test may reveal the level of blood urea nitrogen (BUN) and creatinine, which are waste products that the kidneys filter out of the body. Excessive BUN or creatinine levels could indicate disease.

Blood tests reveal all of this information and more, helping you and your physician make crucial decisions about your health.

How a Science Based Nutrition Blood Test Works

A Science Based Nutrition blood test works differently from a traditional blood test.

Science Based Nutrition is a patented blood analysis system created by Van D Merkle DC, DABCI, DCBN, CCN to go beyond a traditional blood test.

Your physician is unlikely to request a Science Based Nutrition blood test: it’s something you request on your own to learn more about your health.

Science Based Nutrition blood tests solve crucial problems with traditional blood tests:

  • When you request a blood test, labs compare your blood to a “clinical range” to assess your health.
  • This clinical range includes people who are sick – or anyone who has recently visited the lab. The lab doesn’t compare your blood to a healthy population.
  • You might be in a normal range according to that clinical range and assume your blood test is great. In reality, you’re comparing bloodwork to an unhealthy population, skewing results.
  • Because of this, Science Based Nutrition practitioners believe blood tests miss crucial warning signs.
  • A Science Based Nutrition blood test incorporates an “Optimal” and “Healthy” range, giving you detailed insight into your health.

A traditional blood test reveals crucial information about your health and wellness. A Science Based Nutrition blood test reveals even more information – including plenty of things you won’t find on an ordinary blood test.

Science Based Nutrition vs. Ordinary Blood Tests: What’s the Difference?

A growing number of people are choosing Science Based Nutrition (SBN) blood tests instead of traditional blood tests.

What’s the difference between a Science Based Nutrition blood test and an ordinary blood test? Why are SBN blood tests surging in popularity?

Today, we’re highlighting some of the pros and cons of Science Based Nutrition blood tests – including some of the unique insight available with a Science Based Nutrition blood test.

Traditional Blood Tests Use “Normal Ranges” – and That’s a Problem

Science Based Nutrition Ordinary blood tests compare your bloodwork to something called a normal range.

Understandably, people assume a normal range is “normal” – you assume the lab compares your blood to everyone else, helping you compare yourself against the average person.

Unfortunately, that’s not the case with traditional blood tests.

The problem lies in how labs determine normal ranges.

To create a normal range, the lab takes the results of 200 people recently tested with that lab. It tests your biomarkers against this group, then determines if you’re normal.

If these 200 people are healthy and normal, then great! You’re comparing yourself to a good sample size.

Unfortunately, these 200 people can be anyone. Some will be sick. Others will be Olympic athletes with world-class immune systems. Many people get blood tests because they feel something is wrong – which can skew the normal range.

Overall, it does not make sense to compare your blood test results to people who are already experiencing symptoms of a condition. Instead, it makes sense to compare your blood to a normal or healthy population – which is how Science Based Nutrition works.

Science Based Nutrition Compares your Blood to a Healthy or Optimal Population of People Similar to You

Being considered “normal” compared to a sample of 200 people isn’t a good thing. That’s why Science Based Nutrition compares your blood to a different sample.

By comparing your blood to a different group, Science Based Nutrition tells you the “Healthy” and “Optimal” range of your bloodwork.

Instead of comparing yourself to people who are younger or older than you or sicker or healthier than you, you can compare yourself to a more representative sample size. Science Based Nutrition compares your blood to people who are similar to you.

That’s the Science Based Nutrition blood test difference – and it leads to better actionable recommendations.

What You’ll Learn on a Science Based Nutrition Blood Test

With a traditional blood test, the lab sends results to your doctor, and your doctor calls you to say everything is fine.

With a Science Based Nutrition blood test, you get detailed insight into your health and wellness, the best steps to take to optimize your health and wellness, and actionable strategies you can start implementing today to improve.

Some of the things covered in a Science Based Nutrition blood test include:

Individualized Supplement Recommendations: Why does a 125-pound elderly woman have the same recommended supplement serving size as an 18-year old, 250 pound bodybuilder? A Science Based Nutrition blood test can reveal individualized supplement recommendations, allowing you to customize dosage based on your unique needs, age, sex, and weight.

Early Detection & Avoidance: A Science Based Nutrition blood test can spot problems in your blood before you have symptoms, potentially allowing you to get a head start on avoiding a problem. By spotting a condition early, it’s easier to deal with the condition.

Individualized Dietary Recommendations: One person’s dietary needs are considerably different from someone else’s. Unfortunately, when you read dietary information online, it’s catered to everyone – not specifically to you. A Science Based Nutrition blood test can deliver individualized dietary recommendations to help you better understand the best foods to eat.

Top 6 Best Supplements for Immunity

Many people take supplements daily to support immunity.

If you walk through any health food store, you’ll see dozens of supplements claiming to boost immunity in various ways.

Unfortunately, not all immune-boosting supplements are made alike. Some supplements contain junk ingredients. Others are glorified multivitamins priced 10x higher than they should cost.

Fortunately, there are plenty of good supplements for immunity, including proven immune boosters backed by genuine scientific evidence.

Today, we’re highlighting some of the best supplements for supporting immunity.

Vitamin C

You can find vitamin C in any multivitamin. However, some vitamin C supplements contain a much higher dose of vitamin C to support immunity.

Vitamin C is one of the most proven and popular immune-supporting supplement ingredients available today. People have taken vitamin C supplements for decades to support immunity.

Today, research shows that vitamin C does not actually prevent respiratory illnesses – like the cold. However, studies show that vitamin C could reduce the length of time you’re sick with the cold, flu, and other conditions.

In this Cochrane review, researchers analyzed evidence on vitamin C and immunity. They found people who took vitamin C regularly had 8% to 14% shorter cold and flu symptoms than people who did not get sufficient vitamin C.

Vitamin D

Like vitamin C, vitamin D is crucial for immunity. Research has suggested a connection between vitamin D and immunity for decades. Studies show that people who are deficient in vitamin D tend to have weaker immune systems.

Your skin produces vitamin D when exposed to sunlight. Some people also get vitamin D through food sources – like milk. If you live in a northern climate, then you may need to take a vitamin D supplement during the winter to support immunity during the colder, darker months.

This Cochrane review found that vitamin C reduced the number of colds people caught. The benefits of vitamin D supplementation were particularly powerful for those who were already deficient in the vitamin: it reduced the incidence of colds by half compared to a placebo.

Vitamin E

The third and final vitamin on our list, vitamin E has a proven connection to immunity. Research shows that vitamin E can support immunity in all people – but particularly in seniors.

One study published in The Journal of the American Medical Association found 200 IU per day of vitamin E supplementation over one year led to a significant reduction in respiratory infections, particularly upper respiratory infections, including common colds.

At any age, vitamin E is crucial for immunity and overall health and wellness. Consider taking a vitamin E supplement or a multivitamin with vitamin E to support immunity.


Zinc is a crucial mineral required for various body functions. Zinc has been used for decades as a natural immune booster, and modern research shows zinc can have a powerful impact on immunity.

This study showed that zinc reduced the risk of pneumonia in older adults, for example. Other studies have shown that zinc can have powerful immune-supporting effects on people who are deficient in zinc to begin with.

Approximately 12% of adults are deficient in zinc, although as many as 40% of elderly people are zinc deficient. If you aren’t getting enough zinc, then consider taking a zinc supplement for immunity.


Probiotic supplements have never been more popular. Studies show probiotic supplements can help with digestion, bloating, and other issues.

However, growing research shows probiotics can also impact immunity. Over half of your immune system resides in your gut. If your gut isn’t functioning normally, then it impacts immunity.

One review study found that probiotics could help reduce the length of a respiratory infection. Other studies show that probiotics could reduce your risk of developing a respiratory infection at all.

More research is needed to verify the effects of probiotics on immunity, although early research is promising.

Elderberry Extract

Elderberry extract is popular in Europe, where it’s been used for centuries to support immunity. Today, recent research has confirmed with many people already knew: elderberry has genuine immune-supporting benefits.

In this 2004 study published in the Journal of International Medical Research, researchers found elderberry extract reduced the duration of flu symptoms in 60 people between ages 18 and 54.

Similarly, this 2020 study published in the Journal of General Internal Medicine found that elderberry syrup decreased the duration of influenza symptoms, leading to a better outcome in patients compared to a placebo.

Other studies have found elderberry extract could increase the risk of a cytokine storm – so be sure to talk to your doctor before taking elderberry extract or any other supplement on this list.

By taking supplements to support immunity, you could give your body a better chance to fight infections and illnesses – all while relying on natural vitamins, herbal extracts, and minerals found in any supplement store or grocery store.

Top 5 Easy Ways to Support your Immune System at Home

Supporting your immune system has never been more important.

A good immune system can reduce your risk of disease and illness. It can reduce your risk of catching the common cold or flu. It can also reduce the risk of chronic disease.

It’s in your best interest to support your immune system.

Fortunately, researchers know more about immunity than ever. Every day, researchers discover new, easy, at-home ways to support immune function.

Looking for easy ways to support your immune system at home? Here are some of the actionable strategies experts recommend.

Obvious Tips for Boosting Immunity

As Harvard Medical School explains, there are some obvious ways to support your immune system. It’s no secret that smoking, exercising regularly, and losing weight can help support your immune system, for example.

Some of the basic (and obvious) lifestyle habits to boost your immunity include:

  • Stop smoking
  • Eat a healthy, balanced diet
  • Eat more fruits and vegetables
  • Exercise regularly and maintain a healthy weight
  • Drink alcohol in moderation

By implementing these basic strategies today, you can quickly transform your immunity.

Get More Sleep

Sleep plays a crucial role in immune function. If you aren’t getting enough sleep, then your immune system could suffer.

As the Mayo Clinic explains, a lack of sleep can affect your immune system. Multiple studies show that people who get poor-quality sleep – or insufficient sleep – are more likely to get sick after being exposed to a virus, including the common cold virus.

Similarly, lack of sleep can impact your recovery time. If you aren’t getting enough sleep while sick, then it could take significantly longer to recover.

It’s no secret why sleep impacts immunity. During sleep, your body releases proteins called cytokines. Some cytokines promote sleep, while others influence your immune system.

When your body is fighting off an infection or inflammation, it needs more cytokines. When you aren’t getting enough sleep, your body isn’t producing enough cytokines, making it more likely to experience a serious infection or long-lasting inflammation.

It’s not just a short-term lack of sleep: long-term sleep deprivation is associated with a higher risk of various diseases and illnesses. Studies show people who don’t get enough sleep have a higher risk of obesity, diabetes, and cardiovascular disease, among other issues.

Want to supercharge your immunity? Start by getting a good night of quality sleep.

Eliminate Stress

Stress weakens the immune system. When you are stressed, it not only impacts your physical and mental wellbeing – it also makes you more likely to get sick.

Numerous studies have shown stress is linked with immunity. Researchers have found that humans who are stressed have fewer Natural Killer (NK) cells, which your body needs to fight infections and diseases.

When stressed over a long period of time, you weaken your body’s ability to fight everything from diseases and illnesses to chronic infections.

You can stress your body in multiple ways. Exercising too much, for example, weakens your immune system through physical stress.

As this 2004 review study published in Psychology Bulletin explained, psychological stress can weaken your immune system just like physical stress. Researchers analyzed 300 trials over 30 years on psychological stress and immunity. After analyzing evidence, researchers concluded that stress influences immunity due to evolutionary reasons.

Stressed? Try yoga or meditation. They’re proven stress relievers that could help you de-stress – and support your immunity.

Take (the Right) Supplements

Walk into any health food store and you’ll find countless supplements claiming to boost immunity.

Unfortunately, most immune-boosting supplements are junk. Some are multivitamins mixed with trace amounts of herbal extracts. Others use junk science or hidden ingredients to energize your body, tricking you into thinking you have stronger immunity.

Certain natural ingredients, however, have been linked to immune benefits. By taking these supplements, you could support immunity in powerful ways.

A WebMD Medical Doctor (MD) recently reviewed evidence on immune-boosting supplements to create a list of the best ingredients. Some of the most science-backed immune-supporting ingredients include:

Vitamin C: Vitamin C is one of the most popular immune-boosting supplement ingredients available today. Whether you eat foods rich with vitamin C – or take a vitamin C supplement – it’s been shown to support immunity in multiple ways – primarily by acting as a powerful antioxidant.

Vitamin D: Your skin produces vitamin D when exposed to sunlight. Research shows that vitamin D is crucial for immunity. When you take the right dose of vitamin D per day, you’re likely to have a stronger immune system than someone who is deficient in vitamin D.

Vitamin E: Vitamin E could support immune function in seniors. One study found that taking 200 IU of vitamin E per day for one year led to a significant reduction in respiratory infection among a large group of seniors.

Zinc: Zinc is crucial for immune function. If you already get enough zinc, it’s unlikely more zinc will boost immunity. However, if you are deficient in zinc, it could weaken your immunity. Some experts recommend taking a zinc supplement.

Probiotics: Probiotics are beneficial gut bacteria linked to digestion, immune function, and more. Some experts recommend taking probiotics regularly to support immunity.

Glutathione: Glutathione is an antioxidant produced naturally by your body. Some studies show glutathione influences Natural Killer (NK) cell activity, which could influence immunity.

Elderberry Extract: Elderberry extract has been used for centuries as a traditional folk medicine. Today, increasing research shows elderberry extract could influence immunity. One recent study found elderberry syrup led to significantly better outcomes for flu patients compared to a placebo.

Golden Root Extract: One strain of golden root extract, R. Rosea, has been shown to increase the percentage of memory T cells and B cells, both of which play a crucial role in immunity. The study involved just 15 men, so more research is needed to verify the benefits. But early results are promising.

Request a Science-Based Nutrition Testing Kit for Better Blood Test Results

You may have had a blood test as part of a routine physical. However, many experts believe a Science-Based Nutrition blood test is even better.

A Science-Based Nutrition blood test compares your bloodwork to a better population sample.

Instead of comparing your blood to everyone who recently used the lab, a Science-Based Nutrition blood test compares your bloodwork to a normal and optimal population.

When you request an ordinary blood test, the lab compares your results to people who recently used the lab. Many of these people are already sick, which means you’re not comparing your blood to a normal, healthy population.

This skews the results of ordinary blood tests.

That’s why many people choose Science-Based Nutrition blood tests instead.
