Stanford had this drive up fingerstick antibody testing roll out Friday and Saturday. Mark went to Stanford, right? I bet ARYC was there

She also sought to learn if she acquired antibodies from recent on-the-job exposure. “I would like to return back to working,” she said. “Having this information would be very important to me.”

If positive, they’ll get results in several days. If negative, they’ll get no news.

A positive result means they had the virus and recovered. It could also mean they are currently infected and could still transmit the disease.

Antibodies act like sentinels of disease, launching an immediate response if a familiar virus returns. They’re normally produced in a person’s body around seven to 10 days after the initial onset of a virus. The IgM antibodies are generally detectable in blood several days after initial infection, although levels over the course of infection are not well-characterized. The IgG antibodies become detectable later following infection. Positive results for both IgG and IgM indicate recent infection.

It is not yet proven that these antibodies actually provide protection. Related coronaviruses offer a spotty record. Some, which cause the common cold, return again and again. The antibodies to Middle East respiratory syndrome lasted merely a year.

But there are promising clues that COVID-19 might act like it’s closest cousin, the SARS virus, which triggers an immune response that persists for at least three years. In a Chinese study of rhesus monkeys, COVID-19 antibodies protected the animals from a second infection.

If protected, people could potentially return to work. There is also the prospect that the antibodies could be used as therapy against the disease.

Dozens of companies are working to develop antibody tests, as are researchers at the Centers for Disease Control and Prevention.
