Use Sars Cov-2 rapid antigen test kit, the detection result can be get in 10-15min. Sampling the specimen with different swab (oropharyngeal swab, nasopharyngeal swab anterior nasal swab), there are different test process that should be followed. TEST PROCEDURE Allow the test, specimen, buffer and/or controls to reach room temperature (15-30°C or 59-86℉) prior to testing. 1.   Preparation：Open the cap ofextraction tube, transfer the extraction buffer into the extraction tube. 2.   Sample Collection：Use the NP/OP swab provided in the kit to wipetheback wall of the nasopharyngealcavity deep in the nasalcavity (NP swab), or swab overthe lateraland posterior walls of pharynx, as wellas the intratonsillarcleft (OP swab). 3.   Sample Extraction：Insert the swab into the tube,slowly rotate the swab for mixing of the sample and the extraction buffer.Pinch the tube when removing the swab,put the used swab into biohazard bag,and then close the extraction tube with dropper. 4.   Assay procedure：Remove the test cassette from the foil pouch, place the cassette on a clean and level surface .Reverse the specimen extraction tube, holding the specimen extraction tube upright, transfer 3 drops (approximately 80pL) to the specimen well (S) of the test cassette, then start the timer. Interpretation is available within 10-15 minutes.Wait for the colored line(s) to appear. Do not interpret the result after 20 minutes. INTERPRETATION OF RESULTS Positive(+): Two colored lines appear. One colored line should always appear in the control region (C) and another apparent colored line adjacent should be in the test region (T). *NOTE: The intensity of the color in the test line region may vary depending on the concentration of SARS-CoV-2 antigen present in the specimen. Therefore, any shade of color In the testline region should be considered positive. NEGATIVE(-): One colored line appears in the control line region (C). No line appears in the test region(T). INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural techn...

Developed for use on swab samples, the SARS-CoV-2 antigen rapid test kit is a lateral flow immunoassay intended for the qualitative detection SARS-CoV-2 nucleocapsid antigens in nasopharyngealor oropharyngeal secretions. It can be used for the screening of early infected patients and asymptomatic patients and can be used as a supplementary test for SARS-CoV-2 diagnosis. Studies show that the sensitivity and specificity of SARS-CoV-2 nucleocapsid protein antigen rapid test products depend heavily on the raw materials used during Lateral Flow Test Uncut Sheet production. The Lateral Flow Test Uncut Sheet for a SARS-CoV-2 antigen test is the raw material that has been manufactured to produce 80-90 lateral flow test assays on average. It is an easy-to-use, cost-effective, and high-quality medical device for the SARS-CoV-2 test. The Lateral Flow Test Uncut Sheets for the antigen test kit manufactured by Vincenmed(WenSheng) are panels that have not been cut into individual strips. They still contain all the critical parts you require to perform gradient-based rapid testing: nitrocellulose membrane, gold conjugates with sample. Our lateral Flow Test Uncut Sheets are formulated with only high-quality SARS-CoV-2 nucleocapsid protein antigen, making them a reliable source for accurate results. We use superior quality materials, which provide higher sensitivity and specificity and make it one of the best Lateral Flow Test Uncut Sheet materials on the market. Lateral Flow Test Uncut Sheets are rapidly becoming a popular option for laboratories and clinics that need to run high volumes of SARS-CoV-2 rapid tests every day. They can be purchased in bulk at a lower cost than individual strips. Compared with importing the lateral flow rapid test kit, the Lateral Flow Test Uncut Sheet provides more significant profit margin, especially in the regions where labor costs are inexpensive. The Lateral Flow Test Uncut Sheet also provides flexibility when facing time-consuming medical device custom inspections during the SARS-CoV-2 outbreak.

According to WHO recommend，The nasopharyngeal swab / nasal swab is the preferred testing swab for swab-based covid testing. The specific sampling protocol for nasopharyngeal swab is as follows: 1. Gently insert the swab head into the nasal palate in the nasal passages, and after a while, slowly rotate the nasal swab to exit. 2. Quickly put the nasal swab into this sampling tube. 3. Break the nasopharyngeal swab at the breakpoint, discard the handle end and tighten the cap. 4. Freshly collected specimens should be transported to the laboratory within 48 hours (2 days) at 2-8°C. For longer term storage, the specimen should be storage at -70°C or below. After the specimens are sent to the laboratory, nucleic acid extraction should be performed as soon as possible. 5. After sampling, fill in the related information on the tube label. Alternatives to Nasopharyngeal Collection if can not collect by nasopharyngeal specimen, please refer to following options listed, · An oropharyngeal swab / oral swab specimen collected by a healthcare professional (HCP) · A throat swab specimen collected by a healthcare professional (HCP) · An anterior nasal swab / anterior nares swab specimen collected by patient or HCP
