2019 Coronavirus Antigen Rapid Detection Kit

As we all know, the current methods for diagnosing COVID-19 include nucleic acid detection and COVID-19 anti-antigen detection. The establishment of fast and accurate specific detection methods is of great significance to control the epidemic. Antigen and antibody detection reagents may achieve high-pass virus detection. Quantitative screening.

Below are the steps to use the COVID-19 antigen test kit.

First, prepare the antigen test. 1. Wash your hands. Wash your hands with running water or hand sanitizer. 2. Understand the testing process. Carefully read the instructions for use of antigen detection reagents and the precautions related to antigen detection. 3. Reagent preparation. Check whether the antigen detection reagent is within the shelf life, and check whether the contents such as nasal swabs, sampling tubes, and test cards are lost or damaged. If the reagent expires or the contents of the reagent are lost or damaged, the detection reagent should be replaced in time. 4. Confirm the test requirements for ambient temperature and humidity. The detection of colloidal gold test paper generally requires normal temperature conditions of 14°C to 30°C to avoid abnormal test results due to excessive cooling, overheating, or excessive humidity. Unpack the antigen test card and place it in a flat, clean place.

The second is sample collection. People over the age of 14 can do their own nasal swab sampling. Self-testers first blow their noses with toilet paper. Carefully unpack the nasal swab and avoid touching the tip of the swab with your hands. Then tilt the head slightly, hold the cotton swab in one hand, stick the end of the cotton swab into one nostril, slowly walk back 1-1.5 cm along the bottom of the lower nasal passage, and then stick it to the nasal cavity and rotate at least 4 times (the dwell time is not less than 15 seconds), then repeat the same for the other nasal cavity with the same swab. Self-exams for ages 2-14 should be sampled by other adults. When sampling, first blow your nose with toilet paper, then tilt your head slightly. Sampling personnel carefully unpack the nasal swab and avoid touching the head of the swab with their hands. Gently hold the head of the person being collected with one hand, hold the swab with the other hand, insert it into one nostril, and slowly move along the bottom. The lower nasal passages penetrate slowly backward. After 1 cm, stick to the nasal cavity and rotate at least 4 times (the remaining time is not less than 15 seconds), then repeat the same operation for the other nasal cavity with the same cotton swab.

3. Antigen detection. 1. According to the reagent instructions, put the nasal swab into the sampling tube immediately after collecting the sample. The swab head should be spun and mixed in the preservation solution for at least 30 seconds. 5 times to ensure sufficient elution of the sample in the sampling tube. 2. Squeeze the liquid in the swab tip through the outer wall of the sampling tube by hand, then discard the swab. After capping the sampling tube, drop the liquid vertically into the sampling hole of the test card.

4. According to the reagent instructions, wait for a certain period of time to interpret the results. Positive results: red or purple bands are displayed at both "C" and "T", and the color of the band at "T" can be dark or light, all of which are positive results. Negative result: red or purple band at "C", no band at "T". Invalid result: No red or purple band is displayed at "C", regardless of whether the band is displayed at "T". If the result is invalid, you need to take the test strip and test again.

Finally, note the special procedures for handling swab samples. Isolation Observer: Regardless of whether the test result is negative or positive, put all used sampling swabs, sampling tubes, test cards, etc. into a sealed bag, and the management personnel refer to medical waste or dispose of them according to the procedure. Community residents: If the test result is negative, All used nasal swabs, sampling tubes, test cards, etc. will be put into sealed bags and disposed of as general garbage; if the test results are positive, they will be handed over to medical institutions when transferring personnel. waste disposal.
