Description
Technical Field
The utility model relates to the field of rapid detection, in particular to three-pad type detection test paper and a detection kit thereof.
Background
The detection card on the market at present adopts a combination mode of a sample pad and a gold mark pad, the detection card is a main product of POCT, and POCT is an abbreviation of Point-of-CareTesting (Point-of-CareTesting), and the detection card is also called on-site instant detection or bedside detection. It is a medical test method for immediate diagnosis and monitoring at the patient's site or clinical practice. POCT has a faster reaction time and a simpler operation procedure than conventional laboratory tests. The detection card sample pad has the function of removing impurities, and the gold-labeled pad contains gold-labeled substances which can be combined with target substances in the sample liquid. In addition, the detection card also comprises an NC film, and a test line (T line) and a quality control line (C line) are arranged on the NC film. When the sample liquid passes through the NC film, the gold-labeled substance can show different colors on the C line and the T line according to the combination degree of the gold-labeled substance and the target substance in the sample liquid. To achieve a normal chromatographic process, a bibulous paper is introduced to provide the proper suction.
However, although the above components are applied in the prior art, there are some limitations and disadvantages. When the sample is dripped on the sample pad, part of impurities are removed from the sample pad, the liquid is chromatographed upwards, and after the liquid is chromatographed on the gold-labeled pad, the gold-labeled substance on the pad is chromatographed upwards on the NC film together with the sample liquid. In this case, the gold-labeled substance does not have enough time to sufficiently bind to the target substance in the sample solution, and the target substance is chromatographed to the T-line junction on the NC membrane, resulting in a situation where sensitivity is limited.
Only a single sample pad was used in prior art designs for impurity removal. Although the sample pad has some degree of impurity removal, the need for interference immunity, if any, is not considered. In practice, various interfering substances may be present in the sample fluid, such as other non-target substances or environmental pollutants. Because the existing design only depends on a single sample pad to remove impurities, the anti-interference capability of the existing design has defects, and the target substances and the interference substances are difficult to effectively distinguish.
