Phospholipid
Method: Peroxidase Method
Liquid reagent, R1:R2=3:1
CLINICAL SIGNIFICANCE
Phospholipids concentration in the human body can reflect lipid metabolism. It is clinically used for the auxiliary diagnosis of patients with liver and kidney diseases. [1,2]
SENSITIVITY
When the sample concentration is 3 mmol/L, the change of absorbance should ≥ 0.1000.
LINEARITY
In the range of [0.1，12.9] mmol/L ,the linearity correlation coefficient r ≥ 0.990,In the range of [0.1，6.0] mmol/L, the absolute deviation should ≤ ±0.60mmol/L; In the range of（6.0，12.9], the relative deviation should ≤ ±10%.
