Principle of measurement
The analyzer applies the principle of photochemistry and is used with blood lipid test strips (LPS-101, TCS-101, TGS-101, HLS-101) .The whole blood sample to be tested is added into the sample area of the strip. In the process of rapid infiltration, blood cells are filtered out or dissolved. The substrate reacts with enzymes and chemicals in the reaction layer and lead to the color change, then the color intensity is proportional to the concentration of the substance.
The analyzer tests the color intensity of the reaction end point at the wavelength of 620nm, the substance concentration is calculated by the reflection coefficient. When the test strip is LPS-101,with the following formula the concentration of low density lipoprotein cholesterol in (LDL) is calculated, the ratio of TC and HDL can also be calculated.
LDL=TC-HDL-TG/5 (mg/dL)
LDL=TC-HDL-TG/2.2 (mmol/L)
