METHOD FOR IMPROVING DETECTION SENSITIVITY OF COLLOIDAL GOLD IMMUNOCHROMATOGRAPHIC TEST STRIP

摘要

Disclosed is a method for improving the detection sensitivity of a colloidal gold immunochromatographic test strip. The method comprises the following specific steps: phenylmethanol and methanol, at a volume ratio of (9 : 1)-(10 : 1), are selected to be fully and uniformly mixed, so as to obtain a transparent reagent, after a sample to be detected is detected by the colloidal gold immunochromatographic test strip, the transparent reagent is added dropwise into a detection area of the test strip, the test strip is stood up, and after the white detection area of the test strip becomes transparent, the test strip is read by a test strip reading instrument. The above-mentioned operation can increase the detection sensitivity and linear detection range of the colloidal gold immunochromatographic test strip and has the advantages of simple operation and a short processing time.
