The volume measurement, or hct blood test, is the proportion of blood that the red blood cells take up. Hemoglobin, on the other hand, is a density or concentration measurement and is expressed in grams per liter or deciliter. (Hemoglobin is, if you will recall from your high school biology, the iron-based protein that transports oxygen.) RBC is a simple count and is usually expressed as the number of million red blood cells that you have per microliter. Usually, hematocrit is three times the amount of hemoglobin.

Testosterone replacement therapy (TRT) increases hematocrit in most men.  Read more about how to decrease hematocrit.

NOTE: Hematocrit is also part of the CBC panel, so there is no need to order separately if your order already includes CBC.

The most economical lab test panel with 4 tests for men on TRT:

1. Total Testosterone, Liquid Chromatography/ Mass Spectrometry
2. Free Testosterone, Equilibrium Dialysis
3. Ultrasensitive Estradiol, Liquid Chromatography/ Mass Spectrometry
4. Hematocrit

This is a very economical panel that includes: 1- Hematocrit: Portion of total blood volume made up of red blood cells. Testosterone replacement therapy can increase hematocrit. Hematocrit over 52 may increase blood thickness and cardiovascular risks. 2- Total (LC/MS- No upper Limit) and Free Testosterone by Equilibrium Analysis.

This blood donation panel includes these tests: Hematocrit, iron & total iron binding capacity (TIBC), and ferritin.This panel is designed to determine if: 1- Your blood donation or therapeutic phlebotomy was effective in lowering your high hematocrit without negatively affecting ferritin or iron. 2- It is safe to do another blood donation or therapeutic phlebotomy depending on ferritin or iron levels.

This panel provides smart bodybuilders with information that can help minimize potential short- and long-term side effects and risks. This basic bodybuilder panel includes the following gold standard tests/panels: Cystatin C (the only accurate kidney function test for bodybuilders), hematocrit (blood viscosity factor), CMP (glucose, liver & kidney function, and electrolytes), total and free testosterone (LC/MS assay—no upper limit and no interference with anabolics), ultra-sensitive estradiol (the only accurate estradiol test for men), & lipid cholesterol panel. Fasting is required.

 Panel includes:

 - LH and FSH (Pituitary hormones that stimulate testicular cells that can help diagnose primary (testicular) or secondary hypogonadism)

  - Total and free testosterone (LC/MS assay.  No upper limit restriction)

- Prostatic specific antigen (PSA) (TRT is contraindicated for PSA equal or above 4.0)

 - Estradiol (Ultra-sensitive. LC/MS assay)

 - Lipids (LDL, HDL, Triglycerides)

 - Comprehensive Metabolic Panel (CMP) (Glucose, electrolytes,  liver/kidney functions). FASTING IS REQUIRED FOR ACCURATE GLUCOSE TEST.

 - Comprehensive Blood Count (CBC) (Immune cells, red  blood cells, hemoglobin, hematocrit).
