从China供应商批发进口Covid-19 Antigen Lockseal Tube Test Strip — FOB条款

Unique sealing tube test strip series is the main breaking through the invention of amazing biotech, Which can diagnose all the three stages of the covid19 including Virus, antigen, and antibodies. Here we compare the screening method of different types of testing carried out for Covid-19 including nucleic acid, antigen-based, and antibody-based testing. The comparison is done on the basis of sampling specimen, earliest stage detection, time taken by each, Clinical significance of positive results, Specificity, Sensitivity, and technical difficulty. For nucleic acid testing, the specimen used must be nasopharyngeal swabs, sputum, buffer. For antigen specimen, the specimen must be nasopharyngeal swabs, sputum, buffer, urine. And for antibody-based testing, the specimen used must be plasma and serum. Similarly, the earliest stage detection for nucleic acid testing is after infection, and before symptoms arise. Antigen-based testing is also after infection before symptoms arise and antibody-based testing is One week after symptoms arise. The time taken to carry out the nucleic acid test is 60-180 mins, for antigen test is 10 to 15 minutes and for antibody test is 15 to 180 minutes. Product Detail PRINCIPLE Amazing COVID-19 Antigen Lockseal Tube Test Strip is based on sandwich lateral flow immunochromatographic assay highly sensitively detecting COVID-19 nucleocapsid protein in human nasopharyngeal, nasal secretion, saliva or/and serum specimens, having an invisible T (test) zone and C (control) zone. When the sample is applied into the test tube, the liquid will laterally flow on the surface of the test strip. If there is enough COVID-19 antigen in the sample, a visible T band will appear. The C band should always appear after a sample is applied, indicating a valid result. By this means, the device can accurately indicate the presence of COVID-19 antigen in the sample.
