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.

Glossary Term
Any substance, generally a protein, that stimulates the immune system and elicits an immune response. Recognition by the immune system elicits either a T-lymphocyte response, recognizing processed antigens, or a B-lymphocyte response, producing antibodies that bind to unprocessed antigens.
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).
Indicators
A fusion gene that results from a translocation t(9;22)(q34;q11) that fuses the 5' part of the BCR gene to the 5' side of exon 2 of the ABL1 gene. There are 3 potential products that are formed depending on which BCR exon has the breakpoint. All of the protein products have constitutively active tyrosine kinase activity. This fusion is associated with both chronic myeloid leukemia and acute lymphoblastic leukemia.
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 .
