5 Labs Your Doctor Isn’t Ordering (But Should Be)

 


Most people walk out of their doctor’s office feeling reassured…

“Everything looks normal.”

But here’s the truth—normal doesn’t always mean optimal.

Standard lab ranges are designed to diagnose disease, not prevent it. By the time something falls outside of that range, dysfunction has often been building for years.

If you want to truly take control of your health, you have to look deeper.

Here are five labs I recommend regularly in my practice that are not routinely ordered—but can completely change your health trajectory.


1. Fasting Insulin: The Early Warning Sign

Most providers check glucose or A1C. The problem? Those are late-stage markers.

Fasting insulin shows us what’s happening behind the scenes.

You can have normal glucose levels and still be insulin resistant—a condition that drives:

  • Weight gain
  • Inflammation
  • Hormonal imbalance
  • Increased risk for diabetes, Alzheimer’s, and cancer

Optimal Range: 2–6 µIU/mL

If your insulin is elevated, your body is already working too hard to maintain balance.


2. hs-CRP: Your Inflammation Marker

Inflammation is at the root of nearly every chronic disease we see today.

High-sensitivity C-reactive protein (hs-CRP) gives us a snapshot of what’s happening internally—even when you feel “fine.”

Optimal Range: <1.0 mg/L

Elevated levels can point to:

  • Gut dysfunction
  • Chronic stress
  • Poor diet
  • Autoimmune activity
  • Hidden infections

This is one of the simplest markers with the most powerful insight into long-term health risk.


3. Vitamin D: More Than a Vitamin

Vitamin D plays a critical role in immune function, hormone balance, and cellular health.

Yet most people are walking around insufficient—or being told their levels are “fine” when they’re not optimal.

Optimal Range: 60–80 ng/mL

Low levels are associated with:

  • Fatigue
  • Depression
  • Weakened immune response
  • Increased cancer risk

The good news? This is one of the easiest markers to optimize.


4. Homocysteine: The Hidden Risk Factor

Homocysteine is rarely discussed—but incredibly important.

It reflects how well your body is performing methylation, a process essential for:

  • Detoxification
  • Brain function
  • Cardiovascular health

Optimal Range: 6–8 µmol/L

Elevated homocysteine may indicate:

  • B vitamin deficiencies (especially B6, B12, folate)
  • Increased risk of heart disease and stroke
  • Impaired detox pathways

If you’re dealing with brain fog, fatigue, or cardiovascular concerns, this marker matters.


5. Full Iron Panel: The Missing Pieces

Too often, patients are told their iron is “fine” based on a single number.

But iron metabolism is complex—and requires a full panel to understand:

  • Ferritin
  • Serum Iron
  • Iron Saturation
  • TIBC

Why this matters:

You can have low iron symptoms with normal or elevated ferritin—especially in the presence of inflammation.

Or, you may have iron overload, which is rarely caught early.

This panel gives insight into:

  • Energy production
  • Oxygen delivery
  • Inflammation status
  • Overall metabolic health

Why This Matters

If you’ve ever been told “everything looks normal”… but you don’t feel normal—you’re not imagining it.

You’re just being measured against ranges that aren’t designed for optimization.

These labs allow us to:

  • Catch dysfunction early
  • Personalize nutrition and supplementation
  • Prevent disease instead of reacting to it

This is the difference between reactive care and proactive health.


Final Thoughts

You are your best advocate.

Ask better questions. Request deeper testing. Pay attention to how you feel—not just what your labs say.

Because true health isn’t about being “within range.”

It’s about being fully optimized, energized, and thriving.


If you want help interpreting your labs or building a personalized plan, that’s exactly what I do inside my programs at Life Wellness Forever.

The Simple Blood Test That Could Save Your Heart and Your Brain

Elevated levels of homocysteine in the blood are associated with an increased risk of cardiovascular and neurological diseases.

Maintaining optimal homocysteine levels is crucial for overall health, as high levels can lead to inflammation and damage to blood vessels.

Why Test for Homocysteine?

Studies have found elevated homocysteine levels in almost 30% of people older than 65 and more than 40% in people 80 and older.

High levels of homocysteine commonly referred to as hyperhomocysteinemia has long been established as a risk factor for ischemic heart disease, heart attack, sudden cardiac death, premature coronary artery disease, carotid artery stenosis (narrowing), blot clots, stroke, and peripheral vascular disease.

Newer studies have also identified high homocysteine as an independent risk factor for dementia and cognitive impairment.

Homocysteine levels higher than 15 µmol/L are associated with nearly double the prevalence of dementia.

A 2017 study showed that patients with Parkinson's disease and cognitive dysfunction were more likely to have higher homocysteine levels. 

By measuring homocysteine levels, healthcare practitioners can be proactive in their health management, aiding in the prevention of serious medical conditions and promoting overall well-being.

Homocysteine- LabCorp code: 706994

Understanding Homocysteine Test Results

Normal and optimal homocysteine levels should be less than 10 µmol/L.

Levels between 10-15 µmol/L are considered borderline.

Hyperhomocysteinemia is diagnosed with a serum homocysteine level greater than 15 µmol/L. T

Here are three classifications of hyperhomocysteinemia:

Moderate: 16-30 µmol/L

Intermediate: 31-100 µmol/L

Severe: > 100 µmol/L

Causes of Elevated Homocysteine Levels

Factors that can compromise homocysteine metabolism and contribute to elevated levels include:

Comorbid medical conditions: cancer, diabetes, kidney disease, thyroid dysfunction, homocystinuria

Folate, vitamin B6, and vitamin B12 deficiencies (most common)

Dietary factors: excess consumption of alcohol, coffee, and methionine-rich foods

Genetic variations of the cystathionine β-synthase (CBS) and methylenetetrahydrofolate reductase (MTHFR) genes

Older age

Health Concerns of High Homocysteine

Elevated levels of homocysteine damage the inner endothelial lining of blood vessels, promoting inflammation and oxidative stress in the vasculature. This increases the risk of atherosclerosis, a thickening and hardening of arteries caused by plaque buildup, and blood clots. 

There is growing evidence that homocysteine is neurotoxic and decreases blood perfusion to the brain. Elevated levels are associated with neurodegeneration progression, as observed in diseases like Alzheimer's disease. 

Strategies to Lower Homocysteine Levels

Addressing high homocysteine through dietary modifications includes moderating alcohol and coffee consumption and adequately consuming foods rich in folate, vitamin B6, and vitamin B12.

Some of the foods with the highest content of these vitamins are listed below:

Folate: spinach, liver, asparagus, and brussels sprouts

Vitamin B6: fish, organ meats, potatoes, non-citrus fruits

Vitamin B12: fish, meat, poultry, eggs, dairy 

Eating a high-protein diet has also been shown to elevate homocysteine levels. Methionine is found in high quantities in the standard American diet, concentrated in foods like meat, fish, poultry, dairy, and eggs. Limiting the intake of these foods may prevent hyperhomocysteinemia. 

Supplements to Lower Homocysteine Levels

Studies have demonstrated the efficacy of B vitamin supplementation in reducing homocysteine levels.

If your homocysteine is over 10 micromoles per liter, you can lower it by taking B6, B12 and folate. If your homocysteine is above 10 start by taking the pyridoxal-5-phosphate (P5P) form of vitamin B6, 20-to 50 milligrams each day; the methylcobalamin (methyl-B12) and adenosylcobalamin forms of B12, 1 milligram in total each day; and the methyltetrahydrofolate (methyl-folate), starting with 0.8 milligrams (and as high as 5 milligrams) each day.

After three months, recheck the homocysteine to make sure it has dropped to 10 micromoles per liter or lower. In the uncommon cases in which it hasn't, simply add 500 milligrams daily of glycine betaine (also called trimethylglycine).

Re-check homocysteine in another three months. 

If still high reduce the methionine (the amino acid from which the body makes homocysteine) in your diet by limiting consumption of foods such as nuts, beef, lamb, cheese, turkey, pork, shellfish, soy, eggs, dairy and beans.

Research suggests that omega-3 fatty acids effectively reduce homocysteine levels, especially when simultaneously taken with B vitamins. 

Oral N-acetyl cysteine (NAC) supplementation may be considered for preventing vascular events and treating hyperhomocysteinemia. Four weeks of oral NAC dosed at 1.8 grams daily resulted in reductions of serum homocysteine by 11.7% and significant reductions in systolic and diastolic blood pressure.
