How to use the medical test paper kit?

The production of medical test paper kit tells you that antigen detection has the advantages of convenience, speed and low cost compared with nucleic acid detection. Ordinary people can easily achieve home detection. The time to obtain the antigen detection result is within 20 minutes, which can quickly find the infected person and reduce the exposure risk to a certain extent. After the emergence of Omixjon virus strain, due to its stronger immune escape activity and infectivity, the epidemic continued to break out in the world. Sporadic and clustered outbreaks occurred in various parts of China, and the demand for nucleic acid detection showed an exponential growth trend. Therefore, domestic nucleic acid detection adopts mixed detection, from "5 mixed 1", "10 mixed 1" to "20 mixed 1", to meet the growing demand for nucleic acid detection. Antigen detection products can alleviate the detection pressure and provide a good supplement for nucleic acid detection.

Experts believe that the accuracy of antigen detection is related to many factors and needs to be operated in strict accordance with specifications. Antigen detection has four steps:

Medical test paper kit production tells you

1、 Preparations before antigen detection. 1. Wash hands. Wash hands with flowing water or hand sanitizer. 2. Understand the test process. Carefully read the instructions of antigen detection reagents and precautions related to antigen detection. 3. Reagent preparation. Check whether the antigen detection reagent is within the shelf life, and check whether the contents of nasal swabs, sampling tubes, test cards and other items are lost or damaged. If the reagent expires or its contents are lost or damaged, replace the test reagent in time. 4. Confirm the environmental temperature and humidity requirements for the test. The colloidal gold test strip is generally required to be tested at 14 ℃~30 ℃ to avoid abnormal test results caused by overcooling, overheating or excessive humidity. After unpacking, the antigen detection card should be placed in a flat and clean place.

第二，样品收集。14岁以上的人可以自行采集鼻拭子样本。自学成才的考官先用卫生纸擤鼻涕。小心取出鼻拭子的外包装，避免接触拭子头。然后稍微倾斜头部，用一只手握住拭子的尾部，将其贴在鼻孔的一侧进入，沿着下鼻管的底部缓慢地将拭子向后推1〜1.5厘米，然后将鼻腔旋转至少4圈 (保留时间不少于15秒)，然后用相同的拭子在另一个鼻腔上重复相同的操作。2-14岁的自学考官应由其他成年人取样。取样时，用卫生纸擤鼻涕，然后稍微倾斜一下头。采样人员小心翼翼地打开鼻拭子的外包装，避免用手触摸拭子的头部。用一只手轻轻地抓住受试者的头部，将棉签贴在一个鼻孔上进入，沿着下鼻道的底部缓慢地向后穿透1厘米，然后将拭子贴在鼻腔上至少旋转4圈 (保留时间不少于15秒)，然后用相同的拭子在另一个鼻腔上重复相同的操作。

Third, antigen detection. 1. The production of medical test paper kit tells you to put the nasal swab into the sampling tube immediately after collecting the sample according to the reagent specification. The swab head shall be rotated and mixed in the storage solution for at least 30 seconds. At the same time, squeeze the swab head on the outer wall of the sampling tube by hand at least 5 times to ensure that the sample is completely eluted in the sampling tube. 2. Squeeze the liquid in the swab head by hand through the outer wall of the sampling tube, and then discard the swab. After covering the sampling tube, drop the liquid vertically into the sampling hole of the detection card.

Fourth, wait for a certain time to explain the results according to the reagent description. Positive results: red or purple bands are displayed at "C" and "T", and "T" bands can be dark or light, which is a positive result. Negative results: red or purple stripes are displayed at "C", and no stripes are displayed at "T". Invalid result: no red or purple band is displayed at "C", regardless of whether it is displayed at "T" or not. The result is invalid, and the test paper needs to be taken again for retest.
