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 ratio of activated T-lymphocytes expressing CD4 to the total number of T-lymphocytes in a sample expressed as a percent value.
Tests
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.
Tests
Alpha-1 antitrypsin (AAT) testing uses a sample of blood or a cheek swab to diagnose a condition called alpha-1 antitrypsin deficiency (AAT deficiency). This condition is sometimes known as "alpha-." or AATD. If you have AAT deficiency, your body doesn't make enough AAT.
Tests
The determination of the number of helper alpha-beta T-lymphocytes in a sample.
Tests
The determination of the ratio of a sub-population of alpha-beta T-lymphocytes to total alpha-beta T-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.

The determination of the ratio of the alpha-beta T-lymphocytes to total T-lymphocytes present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
An ammonia levels test measures the amount of ammonia in a sample of your blood. Ammonia is also called NH3. It is a normal waste product in your body. Healthy bacteria in your intestines make ammonia when you digest protein in the foods you eat.
Tests
The determination of the ratio of B-lymphocytes to leukocytes that are not T cells or natural killer cells present in a sample. The measurement may be expressed as a ratio or percentage.
Tests
A BCR-ABL1 genetic test uses a sample of blood or bone marrow to look for an abnormal gene called BCR-ABL1. This abnormal gene is found in certain types of blood cancer , such as chronic myeloid leukemia (CML).
