What does the Covid-19 IgG antibody test mean?
The cause of Covid-19 is the SARS-CoV-2 virus. This virus causes mild to severe respiratory illness that has spread globally. This condition is highly contagious and although the symptoms are very usual such as sore throat, fever, loss of smell or taste, etc. however, it is also possible that some individuals might have mild to no symptoms at all.
The antibody test varies from the common swab test that tests to check whether the individual has the disease at present. The antibody test is intended to identify immunoglobulins versus the virus that is responsible for COVID-19. The proteins produced by the immune system are known as antibodies in an acknowledgment of an infection and are particular to that particular infection. The immunizers are seen in the blood and so will need a specimen to be taken from the arm mostly. The sample taken from the individual will be tested for the type of antibody called Immunoglobulin G (IgG).
This specific type of antibody develops in most of the patients having infection for about 2 weeks and remains in the blood after the patient has recovered even though the persistence of the antibody in the blood is unknown. If this antibody is found in the blood, it indicates that an individual might have had COVID-19 in the current past and have received an immune response against the virus. It is not identified yet how much strength antibodies might contribute versus another disease with SARS-CoV-2. This implies that having a certain antibody test does not mean that the person is resistant to COVID-19.
Who are the individuals eligible for this test?
The individuals eligible for the Covid-19 IgG antibody test are:
• A person may have tested negative for COVID-19 previously but did have some symptoms that would normally be expected from individuals with the infection.
• A person has not had typical symptoms, but as many individuals are understood to have had this infection and be asymptomatic.
• An individual has been in close association with an individual assumed of or proved to have COVID-19, or otherwise exposed to the virus.
• A person has recovered from COVID-19. The testing of the sample will help find out if the person has antibodies to COVID-19 and provide a greater understanding of the spread of the virus. The knowledge of the virus will grow as new scientific testimony.
COVID-19 is a new disease, and the awareness of the body’s immune response is inadequate.
What are the advantages and drawbacks of this test?
The advantages include:
• The results can help give some reassurance that a person may have had COVID-19.
• The outcomes of this test might assist in explaining the spread of COVID-19 within the community.
The drawbacks include:
• Imaginable distress, bruising, disease, or other difficulties that can occur at the time of sample collection. Serious complexities are very rare.
• Imaginable inaccurate test results
What is the principle of the Covid-19 IgG antibody test?
This test detects the antibodies generated by the patient against SARS-CoV-2 the virus responsible for the COVID-19 disease. Two types of antibody isotypes can be detected through this test and they are:
There are different types of tests however, the most common test consists of attaching anti-human IgG and IgM antibodies to the cover of the cartridge and linking an antigen of the virus with colloidal gold scraps.
If the specimen of the patient includes anti-SARS-CoV-2 antibodies then these antibodies will connect to the antigen present in the conjugation pad of the cartridge and the network formed will move to the membrane-bound anti-human IgG and/or IgM. A colored chain will then develop on the cartridge.
The level of the IgM antibody begins to increase after 1 week of the first infection, and the IgG appears later than IgM and can persist for 6 months or even numerous years.
Contemplated patients that are affected by SARS-CoV-2 can be immediately recognized by simultaneous monitoring of IgM and IgG. A specimen can be certain if there are IgM, IgG, or both IgM and IgG antibodies present.
There are separate cartridges for rapid tests. In general, for the qualitative disclosure of IgG and IgM at the same time, there are 3 different lines:
• The control
To be confirmed, this examination has to present a positive line for control (C).
What are the features of the Covid-19 IgG antibody test?
When rapid IgM-IgG is combined with an antibody test for COVID-19 is used to detect the IgG and IgM antibodies qualitatively of the new coronavirus in human serum, plasma, or whole blood in vitro. The following are the features:
• Works with whole blood, plasma, and serum
• Tests for both IgM and IgG antibodies done at the same time
• Using the PCR is validated.
• 10 to 15 minutes per test
• Intuitive visual interpretation
• No special equipment is needed
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your Covid Antibody Igg Cmia Blood Serum. Your doctor will give specific instructions depending on your condition on how to prepare for Covid Antibody Igg Cmia Blood Serum.
There is no preparation Required
How is the test performed and how are the results determined?
The steps for the test are:
• The blood or serum or plasma samples are collected from the arm mostly.
• Then the blood or serum or plasma sample is added to the sample well.
• 2-3 drops of the buffer liquid are placed in the sample well.
• The results are read after 10 minutes but not more than 15 minutes.
INTERPRETATIONS OF RESULTS:
• If IgM and IgG are positive - recent infection with SARS-CoV-2.
• If IgM is positive and IgG is negative - recent infection with SARS-CoV-2.
• If IgM is negative and IgG is positive - the previous infection with SARS-CoV-2.
• If IgM and IgG are negative - no infection or not enough detectable antibodies in the early infection.
