Assay principle |
CD4 cell isolation using modified Dynal dynabeads, counting using haematology analyser with specific software |
Ferrous beads coated with MT4 mAb bind to CD4 T cells, which are then removed using magnet. Whole blood and CD4-deplete blood counted on haematology analyser. CD4 count and % calculated using established formulae |
