The a-Hydroxybutyrate dehydrogenase (a-HBD) assay kit is intended for the accurate and direct quantitative measurement of a-HBD activity in human plasma.

Test principle

a-Hydroxybutyrate dehydrogenase (a-HBD) catalyzes the reversible reaction:
Alpha-Hydroxybutyrate Dehydrogenase (alpha-HBD) Assay Kit/Test Kit/Ivd Reagent/Diagnostic
The reaction is monitored spectrophotometrically by measuring the decrease in NADH at 340 nm, and the decreasing rate of absorbance is proportional to a-HBD activity.

Product Features
 
1. Linear range of a-HBD activity: [3, 800] U/L
Linear correlation coefficient ∣r∣≥ 0.990
Linear deviation ≤ ± 10.00%
2. Absorbance of blank ≥ 0.90
3. Changing rate of absorbance of blank ΔA/min ≤ 0.02  
4. Sensitivity
Changing rate of absorbance of blank ΔmA/min ≥ 0.03 while testing the specific a-HBD sample of activity of 274 U/L.
5. Accuracy
Relative deviation is within ±10%.
6. Precision
