Problems solved by technology

[0003] A kind of test paper that uses immunochromatography to test urine microalbumin currently seen in the market is to set only a color-developing box on the NC membrane, and judge whether the test sample is negative or positive by the color of the color-developing box. This color rendering method is not intuitive enough, and the cost is relatively high

Abstract

A test device of trace amount albumin in urine consists of a shell with cover, a test sheet and a window on shell. The said test sheet is prepared as setting flow guide membrane on substrate, setting glass cellulose membrane enveloped by colloidal gold labeled antibody at colloidal gold labeled antibody portion, setting cellulose membrane enveloped with quality control band and detection band on color developing portion as quality control band being enveloped with substance aimed to colloidal gold label and detection band being used to combine with colloidal gold labeled antibody and setting water absorption paper at water absorption portion.

Description

technical field [0001] The invention relates to a biological detection technology, in particular to a urine microalbumin test piece and a test device thereof. Background technique [0002] Microalbuminuria refers to albuminuria that is higher than normal but cannot be detected by conventional methods. Routine examinations can only find patients with urine protein exceeding 150mg / day. The detection of microalbuminuria is an important indicator for the diagnosis of early renal damage. Indexes have received extensive attention, and the diagnosis of early renal damage is far superior to conventional qualitative or semi-quantitative tests. Urinary microalbumin is often seen in diabetic nephropathy, hypertensive nephropathy, preeclampsia in pregnancy, and kidney damage caused by various toxic substances. It can also appear in the urine of occult nephritis and recovery period of nephritis, which is a relatively sensitive early detection important indicator of kidney damage. In re...
