Phagocytic function is assessed by -
Proloiferative response to mitogen
Reduction of NBT (Nitroblue tetrazolium test)
Serum immunoglobulin assay
Skin test with purified protein derivative
Lucocytes from the patients in chronic granulomatous disease fail to reduce nitroblue tetrazolium during phagocytosis. This nitroblue tetrazolium test access the phagocytic activity of leucocytes. Reference : Anathanarayan & paniker's 9th edition, pg no: 175 <\p>
