Interpretive Data
In this test, the percent CD3 cells are those cells that are positive for both CD3 and the alpha-beta chain of the T-cell receptor (TCR) and are presumed immunologically competent.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Analyte Specific Reagent (ASR)
Note
THIS TEST IS FOR TRANSPLANT PATIENTS ONLY. Effective immunosuppressive therapy with OKT3 can be documented by verifying CD3 antigen removal using this test. For immunocompromised patients, order Lymphocyte Subset Panel 4 - T-Cell subsets Percent & Absolute (0095950).
