T-cell receptor gene rearrangement test
(… reh-SEP-ter jeen REE-uh-RAYNJ-ment …)
A laboratory test in which blood or bone marrow cells are checked to see if there is a certain change in the genes that make receptors on T cells (white blood cells that fight infection). Testing for this gene change can tell whether large numbers of T cells with a certain receptor are being made. This may be a sign of cancer.
