How do you estimate catalase levels in blood?

To estimate catalase levels in blood, a common method involves measuring the decomposition of hydrogen peroxide (H2O2) by catalase. A blood sample is treated with a specific concentration of H2O2, and the rate of oxygen production is monitored, typically using a spectrophotometer to measure changes in absorbance. Alternatively, enzyme activity can be quantified using colorimetric assays that involve the formation of a colored product in the presence of catalase. These methods provide a quantitative assessment of catalase activity in the sample.
