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.
