Test performed by: LabPLUS Cell Markers


For Investigation of Immunodeficiency

 

The absolute numbers of CD3 (total T lymphocytes), CD4 (T helper lymphocytes), CD8 (T suppressor/cytotoxic lymphocytes), CD 19 (B lymphocytes) and CD 56 (NK lymphocytes) positive cells may be determined by flow cytometry in the Cell Markers Section of the Haematology Laboratory. 

For all queries, including specimen requirements and results, contact the Cell Marker section of the Haematology laboratory ( Ext22061 or 22075),
