Principle
ADA catalyzes deamination of adenosine to inosine which is then converted to hypoxanthine by purine nucleoside phosphorylase (PNP). Hypoxanthine is then converted to uric acid and hydrogen peroxide (H2O2) by xanthine oxidase (XOD). H2O2 is further reacted with N-Ethyl-N-(2-hydroxy-3- sulfopropyl)-3-methylaniline (EHSPT) and 4-aminoantipyrine (4 AAP) in the presence of peroxidase (POD) to generate quinone dye.

Quality Control
To ensure adequate quality control, it is recommended that
each laboratory should use a normal and an abnormal
commercial reference control material. It should be realized
that the use of quality control material checks both reagent
and instrument functions together. Factors which might affect
the performance of this test include instrument function,
temperature control, cleanliness of glasswares and accuracy
of pipetting.
