Test Code IP IMMUNODEFICIENCY PANEL (T-CELL SUBSETS ONLY)

Important Note

Hemagram and differential (CBCDF) are required for total CD4 count (absolute). Outside clients may submit a hemagram with differential from their own instrumentation with the sample or place an order for a CBCDF and also submit a lavender top tube (EDTA) for testing. If the CBCDF will not be tested within 12 hours, also submit a properly labelled smear. A CBCDF must be performed within 24 hours of the subset analysis, however a CBCDF drawn at the same time is optimal.
