Covid 19 Rapid Test Kit- MADE IN USA- FDA APPROVAL PENDING
After covid-19 virus invades the human body, the human body will produce corresponding specific antibodies for defense. Among them, the specific antibody IgM is produced at the earliest and performs early defense, and then produces IgG antibodies.
we have studied COVID-19 patients and found that after the virus invades the human body, it takes about 3-7 days to produce IgM antibodies, and IgG antibodies are produced in 10-15 days.
This Rapid year offers lateral flow devices for the detection of IgG and IgM antibodies to the corona virus N-protein in serum, plasma, and peripheral blood.
When IgM (+) IgG (-)：
it indicates that the patient is in the early stage of infection
IgM (+) IgG (+) indicates that the patient is in the active phase of infection, but has produced persistent immune IgG antibodies.
When IgM (-) IgG (+)：
it indicates that the previous infection, the virus has been cleared.
IgM (-) IgG (-):
it indicates that you are a healthy person, or the patient may be in a “window period”, the body has not produced relevant specific antibodies or the antibody content is low, resulting in no detection in the laboratory.
