Drabkin's Reagent is used for the quantitative, colorimetric determination of hemoglobin concentration in whole blood at 540 nm. Drabkin's Solution reacts with all forms of hemoglobin except sulfhemoglobin, a pigment that normally occurs in only minute concentrations in blood.

Application

Drabkin′s reagent is used in measuring haemoglobin from blood samples. It comprises potassium ferricyanide, potassium cyanide and potassium dihydrogen phosphate as components. Potassium ferricyanide oxidizes haemoglobin to methemoglobin and then to cyanmethemoglobin.
