Antibody tests not all equal
When a person is infected with the coronavirus, a test, using samples taken from a kind of large cotton swab in the nose or throat, can confirm that the virus is active in their body. After the contamination period, the person's blood can be tested for antibodies specific to the coronavirus. This type of test, known as serology, allows you to see if she has already encountered the coronavirus, even without knowing it, as is common. When the immune system encounters a virus, it stores its memory in the form of antibodies.
But all antibody tests are not equal and do not tell whether the person, while having encountered the virus, has enough antibodies to be protected against future infection. A Chinese study pre-published this week, and not validated by a reading committee, showed that some of the former patients had relatively low levels of antibodies in the blood. In Washington on Wednesday, a private medical center announced that it was now offering a rapid 15-minute serology test, but the patient had to pay $ 290 for the consultation and the test.
