The determination of the amount of lymphocyte antigen T1/Leu-1 in a sample.
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.
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.
Tests
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
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).
Tests
A bilirubin in urine test measures the levels of bilirubin in your urine. Normally, bilirubin isn't found in urine. If there is bilirubin in your urine (called bilirubinuria), it may be an early sign of a liver condition .
