An antibody test can, with very high accuracy, determine if you have had a Covid-19 infection or not. A complete infection with antibody response gives an increased resistance. At present, it is not known whether we will have a marginally increased defense or full immunity. A test can give you increased support in decisions in everyday life or support in how to distribute your resources in an organization or in a company.
If two or more streaks appear, it indicates an ongoing or ongoing infection. A doctor will explain what this means for you.
Based on previous experience, it is unlikely that you would be re-infected with Covid-19 and become ill a second time during the same season. It is not clear if the virus mutates and in that case can reinfect next season. In the event that the antibody protection disappears next season, you can probably be reinfected.
It's about 2%
It is transmitted mainly through droplet infection, ie when someone coughs, sneezes or speaks. An arm's length distance is usually sufficient to avoid exposure.
CE means that the test has been reviewed by a European authority, ensured that it meets standards for sale and free movement within the EU. A CE-certified medical device is under the control of the Medical Products Agency and may be sold freely on the Swedish market.
This means that your immune system is equipped with defense mechanisms of sufficient quantity and accuracy and in the right place in the body to be able to ward off an attack by a microorganism without you getting any obvious symptoms or that you become contagious.
The blood is dropped on a test strip of nitrocellulose prepared with colloidal gold-labeled antigen. If antibodies are present, these complexes form Ig and the colloidal gold-labeled antigen and are sucked up into the membrane by capillary force. At each IgM / IgG line, there are nitrocellulose-immobilized anti-human mouse IgM / G antibodies, which bind and form complexes with the antibody / colloidal gold-antigen complex and a red line appears.
The non-captured immune complexes migrate further and bind at the control line.
It is up to your employer how they want to organize the work at your workplace. At the individual level, continued caution is recommended. It is not recommended to deviate from FHM's instructions. You are responsible for how you choose to handle your test result.
The two most common:
a) Serological tests, what we have here - a test that shows the presence or absence of antibodies. This test can show a long-term infection (months - years). Worse to detect an acute ongoing infection. The sample material consists of serum, plasma or whole blood.
b) Nucleic acid detection - PCR - a type of test where you look for a specific sequence of eg a virus and look for its presence in a sample. This provides a snapshot of whether the virus is present in the patient at this time. Gets negative early in the process and when the virus is no longer present in the body. Cannot detect past infection. Taken via tops in nose / throat / rectum.
We only test you if more than 7 days have passed since you fell ill and you have been problem-free for at least 48 hours. NOTE! No exceptions are made to this rule!
