Tests
The determination of the amount of total 17-ketosteroids present in a sample.
Tests
The determination of the amount of total 3-nitrotyrosine in a sample.
Tests
The total number of white blood cells that are basophils. It is calculated by multiplying the white blood cell count by the percent of basophils in the differential white blood cell count.
Tests
The total number of white blood cells that are eosinophils. It is calculated by multiplying the white blood cell count by the percent of eosinophils in the differential white blood cell count.
Tests
The measurement of the number of helper T lymphocytes, which are T lymphocytes that express CD4, in a cubic millimeter of blood. It is calculated by multiplying 1000 by both the total leukocyte count and the percent of helper T cells in the differential leukocyte count.
Tests
The measurement of the number T lymphocytes, which are leukocytes that express CD3, in a cubic millimeter of blood. It is calculated by multiplying 1000 by both the total leukocyte count and the percent of T cells in the differential leukocyte count.
Tests
The measurement of the ratio of activated T-lymphocytes expressing CD4 to the total number of T-lymphocytes in a sample expressed as a percent value.

An AFP tumor marker test is a blood test that measures the level of AFP (alpha-fetoprotein) in a sample of your blood. AFP is a protein that the liver makes when its cells are growing and dividing to make new cells. AFP levels are normally high in a fetus, but after birth, they drop very low. Healthy children and adults who aren’t pregnant have very little AFP in their blood.
