Problems solved by technology

[0004] But so far, there is no colloidal gold immunochromatography device that can be used for automatic quantification, and there is no colloidal gold immunochromatography quantitative detection method that is matched with it.
Moreover, the existing reagent strips cannot be directly used for quantitative detection due to the uncertain concentration of the quality control tape coating.

Embodiment 2

[0038] This embodiment is a specific application example of the operation interface of the detection system using the colloidal gold immunochromatography quantitative detection device for prenatal screening.

[0039] 1. System introduction

[0040] Down's syndrome (Down's Syndrome) is the most common chromosomal abnormality, accounting for 1% of the number of conceptions, and there is 1 child with Down's syndrome in every 700 births. Because Down's syndrome cannot be treated at present, only early diagnosis and termination of pregnancy can achieve the goal of eugenics. This system adopts a comprehensive screening method, according to multiple data such as maternal age, pregnancy time, maternal weight, concentration of alpha-fetoprotein (AFP) in maternal blood, chorionic gonadotropin (hCG) and other recessive factors. It is a relatively accurate evaluation algorithm recognized by the academic circles, which is used to evaluate pregnant women in the second trimester (14 to 23 w...

Abstract

The detecting device comprises of the reagent strip, the reagent plate, the scanner, the data processing device, the output device and IC card. The reagent strip with the quality control strip and the detection strip being coated is stuck on the reagent plate fixedly. The density and the scanning time are stored on the IC card. With the parameters on the IC card being read out, the data processing device control the scanner to scan the reagent strip and the signals collected are transferred back to the data processing device. After the optical density value of the quality control strip and the detection strip being recognized, calculated and analyzed, the result is transferred to the output device. The invented detecting device provides the quantified detection with the precision and the accuracy accorded with the requirement.

Description

1. Technical field [0001] The invention relates to a device for medical clinical detection, in particular to a colloidal gold immunochromatography detection device capable of full quantitative and semi-quantitative detection, and also relates to a detection method for the detection device. 2. Background technology [0002] Colloidal gold immunochromatography (GICA) is a rapid clinical diagnostic technique that has emerged in foreign medical circles in recent years. It is characterized by single-serve determination, simple and fast, and does not require any equipment except commercial reagents. That is, the results can be observed with naked eyes, and the storage time is long. The variety of GICA reagents is also becoming more and more abundant. At present, there are dozens of kinds, including alpha-fetoprotein (AFP), human chorionic gonadotropin (hCG), luteinizing hormone (LH), and hepatitis B surface antigen (HBsAg). , cocaine (Cocaine), marijuana (Maruuana), etc., and the...
