Results should be interpreted in the context of the clinical history, including medication history, examination findings and other laboratory data, rather than in isolation, and whether the patient was clinically ill at the time of testing.
This test measures the amount of immunoglobulins, also known as antibodies, in your blood. Antibodies are proteins made by the immune system to fight disease-causing substances, like viruses and bacteria.
Jul 12, 2022 · information below will help you understand what your test results mean. POSITIVE ANTIBODY TESTS A positive antibody test means the test has detected high levels of antibodies (above a certain amount) in your blood. It does NOT mean you are currently infected with COVID-19. Nucleocapsid Antibody Test Your test result message says:
- Sensitivity, Specificity and Predictive Values
- Timing
- Cross-Reactivity
- Antibodies = Protection?
As with any good diagnostic test, COVID-19 antibody tests need to be highly sensitive, which means that most people who have had the disease get a positive result; and highly specific, which means that most people who have not had the disease get a negative result. According to a recent Cochrane review, current COVID-19 antibody tests are around 90...
The reliability of the test result will also depend on how recently a person has contracted COVID-19. It takes time for the immune system to produce antibodies at a high enough concentration to be detectable. According to the Cochrane review, only 30% of people will test positive if they undergo an antibody test one week after developing symptoms. ...
Antibodies developed in response to other coronaviruses, such as the virus that causes the common cold, may have a very similar structure to antibodies against SARS-CoV-2. This means that the presence of these antibodies in the blood may be sufficient to produce a positive test result, even in a person who has never had COVID-19. It is possible tha...
Even taking all of these factors into account, we do not yet know whether looking for antibodies is even a good way to establish whether a person is immune to COVID-19 or how long this immunity might last. Antibodies are just one part of a complex immune responsethat is triggered when a person becomes infected with SARS-CoV-2. Lack of antibodies do...

Apr 4, 2022 · Result interpretation and SARS-CoV-2 antibody mechanics. The levels of antibody (antibody titre) produced after vaccination or infection vary.
Antibodies against SARS-CoV-2, which is the virus that causes COVID-19, can be measured in your blood. These COVID-19 antibody levels are at their highest (peak) about 28 days after vaccination or after infection with COVID-19 and then slowly fall.
