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.

Compliance Statement A: For laboratory developed tests using a manufacturer labeled ASR as the reagent providing the specificity of the assay. Analyte Specific Reagent. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, the FDA has determined that such clearance or approval is not necessary.

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).
