COVID 19 Antigen Test Kit-Saliva (Colloidal Gold Method)
date：2021-09-19 00:14
[INTENDED USE]
This reagent is used for in vitro qualitative test of COVID 19 antigen N protein in human saliva samples.
It is only used as a supplementary test indicator for suspected cases with negative result of COVID 19 test. It cannot be used as a basis for confirmation or diagnosis of pneumonia caused by COVID 19 infection. A positive test result needs further confirmation, and a negative test result cannot exclude the possibility of infection.
The 2019 novel coronavirus is also known as COVID 19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the COVID 19 are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.
[TEST PRINCIPLE]
COVID 19 Antigen Test Kit-Saliva (Colloidal Gold Method) was prepared by colloidal gold solid-phase immunochromatography. A monoclonal antibody COVID 19 N protein was pre immobilized on the cellulose nitrate membrane. The monoclonal antibody against the COVID 19 N protein was labeled on colloidal gold on the glass fiber membrane. The double antibody sandwich immunoassay was used to detect the N protein of the COVID 19. The kit used for in vitro qualitative auxiliary test of COVID 19 antigen samples.
When testing, add 3 ~ 4 drops of pretreated sample (about 100μL) into the sample hole (S) of the test card. If the COVID 19 antigen is contained in the sample, COVID 19 antigens in the sample can form colloidal gold complexes with colloidal gold labelled antibodies. The composite is moved forward along the test strip along with the test strip and captured at the test line location (T) of nitrocellulose membrane. The excess unconjugated colloidal gold labeled antibody continued to move forward to the position
