The gold standard pen type card is mainly used for chromatographic colorimetric quantitative detection of biochemical indicators in body fluids. Our company adopts technology and equipment for mass production, further improving product performance on the original basis.

At the same time, the preparation process of gold standard pen type cards is simple and cost-effective. And it includes a test strip, which is encapsulated in the detection card body. The detection card body is provided with sampling holes and observation holes, and it is worth noting that the test strip includes a bottom plate. The bottom plate of the test strip is sequentially equipped with absorbent paper, nitrocellulose film, gold label pad, and sample pad. The absorbent paper and gold label pad are respectively set at both ends of the nitrocellulose film. At the junction of the two ends of the nitrocellulose film, a small section of the absorbent paper and gold label pad overlaps and presses on the nitrocellulose film. The sample pad is set at the other end of the gold label pad, and a small section of the sample pad overlaps on the gold label pad.
