As COVID-19 spread around the world since the end of 2019, our worlds has suffered a lot and COVID-19 brought trouble to almost every fields of our lives. So people have done their best to fight the COVID-19 epidemic. In purpose of fighting against the COVID-19 virus, we need to know who is infected with the COVID-19 and take suitable measure to stay away from them and take appropriate treatment for them. Now, Singclean Rapid COVID-19 Antibody Test Kit (Colloidal Method) is launched by Singclean Medical for fighting the epidemic. It is a rapid, precise and effective test kit for screening out who is infected with COVID-19.
The novel coronaviruses belong to the β genus. COVID-19 is an acute respiratory infectious disease.
People are generally susceptible. Currently, the patients infected by the novel coronavirus 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.
What is Antibody?
Antibody also called immunoglobulin, it is a protective protein produced by the immune system in response to the antigen. Antibodies recognize and latch onto antigens in order to remove them from the body. A wide range of substances are regarded by the body as antigens, including disease-causing organisms and toxic materials such as insect venom. As someone is infected with COVID-19 virus, immune system will produce antibody to fight against the virus. IgM antibody will appear after 7 days of COVID-19 symptoms appears and igG antibody will appear after 10 days of COVID-19 symptoms appars.
What is Singclean COVID-19 Antibody Test Kit?
Singclean COVID-19 Antibody Test Kit is a rapid, precise and effective test kit for screening out who is infected with COVID-19. Based on solid phase immunochromatographic assay, it can detect antibody from COVID-19 virus in blood sample.
If someone is infected with COVID-19 virus, his antibody will be produced to fight against the COVID-19 virus: the igM antibody normally appears 7 days of symptom onset, igG antibody can be detected from 10 days of symptom onset. Based on this principle, Singclean COVID-19 Antibody Test Kit can be applied for detection of antibody of the COVID-19 and screening out who is infected with COVID-19 virus, for only 10 minutes you can read the test result.
1, Fast: for only 10minutes you can read the test result, it save a lot of time than PCR nucleic acid test method which costs 3-4 hours to read the test result. Due to the short testing time, the COVID-19 antibody test kits can be applied for a large scale.
2, Precise: as our research shows, the accuracy of Singclean COVID-19 Antibody Test Kit compared with PCR is about 97.84%! So it is ok to test the COVID-19 virus.
3, Easy Application: the test procedure is not complicated. It can be applied for large scale of testing.
Nevertheless, during test procedure we need these materials below we don't supply:
1,Specimen collection containers
2, Centrifuge (for plasma only)
Allow test cassette, specimen, buffer and/or controls to equilibrate to room temperature (15-30°C) prior to testing.
1. Remove the test cassette from the sealed foil pouch and use it as soon as possible. Best results will be
obtained if the assay is performed within one hour.
2. Place the test device on a clean and level surface.
For Serum or Plasma Specimens:
With the provided dropper, draw serum/plasma specimen and then add 1 drop serum/plasma specimen
into the sample well(S). Then add 2 drops of buffer to the sample well(S) immediately. Avoid air bubbles.
For Whole Blood Specimen:
With the provided dropper and transfer 1 drop of whole blood to the sample well(S) of the test device, then add 2 drops of buffer to the sample well(S) immediately. Avoid air bubbles.
3. Wait for the colored line(s) to appear. The result should be read after 10 minutes. Do not interpret the
result after 20 minutes.
4. Read the test result. If the C line and IgM line are both lighten, the result is IgM positive. If the C line and the IgG line are both lighten, the result is IgG positive. If all the lines lighten, the result is IgM and IgG positive. If only the C line lighten, the result the negative. If no C line lighten, the test the invalid.
1.Use fresh samples whenever possible. Frozen and thawed samples (especially repeatedly) contain
particles that can block the membrane. This slows the flow of reagents and can lead to high background
color, making the interpretation of results difficult.
2.Optimal assay performance requires strict adherence to the assay procedure described in this insert
sheet. Deviations may lead to aberrant results.
3.A negative result for an individual subject indicates absence of detectable anti-COVID-19 antibodies.
However, a negative test result does not preclude the possibility of exposure to or infection with
4.A negative result can occur if the quantity of the anti-COVID-19 antibodies present in the specimen is
below the detection limits of the assay, or the antibodies that are detected are not present during the stage of disease in which a sample is collected.
5.Some specimens containing unusually high titer of heterophile antibodies or rheumatoid factor may
affect expected results.
6.As with all diagnostic tests, a definitive clinical diagnosis should not be based on the result of a single
test, but should only be made by the physician after all clinical and laboratory findings have been evaluated.
