"Ideal" Values
for Lab Tests

What Lab Tests Do We Use?


There are two types of lab tests used in RCP Consults:

  1. Blood Work
  2. Hair Tissue Mineral Analysis (HTMA)

(Click here if you need help ordering these tests.)

These lab tests are vital to helping you understand your “mineral-stress” pattern, and for helping you track progress as you follow the steps of The Root Cause Protocol.

At the end of this article are links to labs in several different regions of the world to assist you.

Important Note About "Ideal" Values


Everyone wants to know what the “ideal” or “optimal” values should be. This is a perfectly logical question.

But PLEASE note, that is a very simple question with a very complex answer…

Think of it this way: The range of body temperature is 92˚F – 108˚F (or 32˚C – 45˚C). And the “ideal” body temperature is supposed to be 98.6˚F (or 37˚C). The closer you get to either “bookend,” the more likely symptoms will appear. And the closer you get to “ideal”, the better.

But there will ALWAYS be variation among individuals, so do not look at lab values in a vacuum apart from individual symptoms.

Blood Work


The “Full Monty” Blood Panel w/ Vitamins A & D measures the following markers.  (Included below is a short description of what each test is measuring, and what I consider to be the “ideal” values for each.  But PLEASE remember the caveat at the beginning of this page.  Click here if you need help ordering tests.)

  • Iron
    • Serum Ferritin
      • USA & Metric: ~20-50 ng/mL
      • This measures the protein that stores Iron in the tissues.
    • Serum Iron
      • USA: ~100 ug/dL for women, ~120 ug/dL for men
      • Metric: ~17.9 mmol/L for women, ~21.5 mmol/L for men
      • This measures “efficiency” of Iron; similar to measuring miles-per-gallon (MPG) in a car.
    • Total Iron-binding Capacity (TIBC)
      • USA: ~285 ug/dL for women, ~340 ug/dL for men
      • Metric: ~51 ug/dL for women, ~60.9 ug/dL for men
      • If reported as “% Saturation”, should be 25-30%
      • This measures how many “docking stations” are available for Iron.
    • Serum Transferrin
      • USA: ~300 mg/dL, or ~3.0 g/L
      • Metric: ~1.35 mmol/L
      • This measures the key “transport” protein that “recycles” Iron from tissue back into the blood stream.
    • Hemoglobin
      • USA: ~12.5 g/dL for women, ~13.5 g/dL for men
      • Metric: ~125 g/L for women, ~135 g/L for men
      • A protein responsible for transporting Oxygen.
  • Copper
    • Serum Ceruloplasmin
      • USA: ~35-40 mg/dL
      • Metric: ~0.35 g/L
      • A marker of “bio-available” Copper, which regulates Iron.
    • Serum Copper
      • USA: ~100 ug/dL
      • Metric: ~15.7 umol/L
      • Measures the total amount of Copper in your blood.
  • Magnesium
    • Magnesium RBC (Red Blood Cell)
      • USA: ~6.5 mg/dL
      • Metric: ~2.67 mmol
      • Measures the amount of Magnesium in the red blood cells.
  • Zinc
    • Plasma Zinc
      • USA: ~100 ug/dL
      • Metric: ~15.3 umol/L
      • Measures the amount of Zinc in plasma/serum.
  • Vitamin A
    • Retinol
      • Should be 10 times higher than Vitamin D
      • Measures the amount of “active” Vitamin A in your blood.
  • Vitamin D
    • 25[OH]
      • USA: ~15-30 ng/mL
      • Metric: ~37.5-75 pmol/L
      • Measures the amount of “storage” Vitamin D (or Calcidiol) in your blood.

Hair Tissue Mineral Analysis (HTMA)


The HTMA test helps to reveal your “mineral-stress” pattern.  It is a very useful tool.

HOWEVER… there are no “optimal” or “ideal” numbers.

AND… results are not correlated to your nutrient intake.

These numbers (and their ratios) are reviewed during RCP Consults.

Feeling confused?


This can feel very confusing, even overwhelming…
