Final answer:
The Cyanmethemoglobin method is a safer alternative to Drabkin's reagent as it uses a non-toxic reagent called Cyanide-free Hemoglobin Reagent.
Step-by-step explanation:
Drabkin's reagent is a solution typically used to measure hemoglobin levels in blood. However, since it contains toxic substances like potassium ferricyanide, it can be dangerous to use. Fortunately, there are safer alternatives available such as the Cyanmethemoglobin method.
The Cyanmethemoglobin method involves converting hemoglobin into cyanmethemoglobin, a stable compound that can be measured spectrophotometrically. This method uses a reagent called Cyanide-free Hemoglobin Reagent. It is non-toxic and provides accurate results, making it a safer alternative to Drabkin's reagent.
