Limitations
The kit used to perform this test is labeled for RESEARCH USE ONLY. Performance characteristics have been determined by med fusion. This test has not been cleared or approved by the U.S. Food and Drug Administration (FDA).
Reference Range
An interpretive report will be provided.
Clinical Significance
This assay is used to identify clonal rearrangements of the T-cell receptor gamma chain gene and the T-cell receptor beta chain gene present in the majority of T cell and certain B cell malignancies.
