Tesla Chief Executive Officer (CEO) Elon Musk on November 13 shared results of his COVID-19 tests, and said "something extremely bogus is going on".
In a tweet, Musk said he tested positive on two rapid antigen tests, but tested negative on two other tests.
In a later tweet, Musk said he had symptoms of a typical cold, and "nothing unusual so far".
The Tesla CEO said he is awaiting results from PCR tests for the novel coronavirus from separate labs, which will take 24 hours.
Some research has suggested that rapid antigen tests are less sensitive than RT-PCR tests while detecting the coronavirus.
Something extremely bogus is going on. Was tested for covid four times today. Two tests came back negative, two came back positive. Same machine, same test, same nurse. Rapid antigen test from BD.— Elon Musk (@elonmusk) November 13, 2020
If it’s happening to me, it’s happening to others. I’m getting PCR tests from separate labs. Results will take about 24 hours. — Elon Musk (@elonmusk) November 13, 2020

Musk was possibly referring to the rapid antigen tests of US medical technology company Becton Dickinson, Reuters reported.
Becton Dickinson, which is one of the major suppliers of COVID-19 antigen tests, said in September it was investigating reports from US nursing homes that its rapid coronavirus testing equipment was producing false-positive results.
Earlier in November, the US Food and Drug Administration said it was alerting clinical laboratory staff and healthcare providers that false positive results can occur with COVID-19 antigen tests.
Musk had previously criticised coronavirus-related restrictions and lockdowns, referring to those as "fascist" and an infringement on individual liberty.
Becton Dickinson had not yet respond to a request for comment by Reuters.
