Project Description

COVID 19 IgG & IgM Detection Kit

COVID-19: How to detect?

Detection method Serum antibody test RT-PCR
English full name Immunoglobulin M (IgM) Immunoglobulin G(IgG) Reverse transcriptase PCR.
Principle Detection of Immunoglobulin M (IgM) and Immunoglobulin G (IgG) in blood Check whether the RNA of the target virus is present in the specimen, and compare the genetic sequence of the suspected infected person with the SARS-CoV-2 virus, positive Positiverepresentatives confirmed diagnosis.
Detection method Blood The nasal mucus, saliva, or sputum at the nasopharynx is tested, and the presence of the virus is detected by RNA to DNA.
Applicable situation Test for the presence of antibodies Test for virus presence
Applicable timing Do a general quick screening to determine whether it may be infected.
If both IgM and IgG are positive, it is recommended to go to the hospital for PCR testing.
The suspected confirmed diagnosis shall be handled by professional medical institutions and medical care/testing personnel.
Test results IgM positive, IgG negative = Early infection.
IgM positive, IgG positive = Strong infectivity.
IgM negative, IgG positive = Serious condition.
Positive = Most viruses are present, which can be described as a confirmed diagnosis.
Time required The result of a quick screening can be made in about 8 minutes It takes about 8-9 hours to get a conclusion.

1. Cleaning the finger with an alcohol swab.

2. Twist the cap off the lancet.

3. Press lancet firmly againts the collection site to puncture the finger.

4. Press the blood collection site with thumb to collect enough blood sample.

5. Collection the blood sample with plastic pipette dropper.

6. Draw blood into the sample dilent vial and mix with dropper gently.

7. Add 2 drops of the premixed blood sample to the specimen well of the test device. Take care to avoid bubbles.

8. Read test result at 5-8 minutes. Results measured after 20 minutes are invalid and should be discarded.
