Cellular Immunology

The enumeration of lymphocytes and their subsets and assessment of lymphocyte and neutrophil function in-vitro requires varying volumes of blood in plain tubes, EDTA-containing tubes and heparin-containing tubes. Sterile conditions also apply in some assays. Such investigations are not available without prior arrangements with the laboratory (please phone ext 42184).  Full details of specimens required will be given when tests are arranged. For lymphocyte surface markers in known HIV disease (CD3, CD4, CD8), 4mL of blood in EDTA should be taken and sent directly to the laboratory, which should be informed by telephone. Please contact the laboratory before taking the blood.

If you have any doubts about sample requirements, contact the laboratory for advice.
