Americans may be able to soon test themselves to determine their exposure to COVID-19.

INDIANAPOLIS (WTHR) — Americans may be able to soon test themselves to determine their exposure to COVID-19.

According to NBC News, a Los Angeles health care company called Scanwell Health is looking for government approval of a kit that would let users submit a scanned image of a blood test to doctors through their phones.

"A positive test result means a patient has been exposed to COVID-19 at some point in the past and has developed antibodies to fight it," NBC News reported.

How it works:

Eligible patients will have a test kit sent to them

The patient uses the kit to prick their finger and place a blood droplet onto a test cassette

After 15 minutes, the results appear and the patient would need ot upload an image of it via the Scanwell Health app

A doctor or nurse would deliver test results within a few hours.

Although the test can tell if a person has been exposed to COVID-19 and has antibodies against the virus, it can't tell a person whether they're currently infected with coronavirus.

For that reason, it would need to be used in combination with other information to determine if a person has COVID-19, NBC reported.

Scanwell Chief Medical Officer Jack Jeng said that antibody testing is only one piece of the puzzle and just because you could test positive for them doesn't mean you're necessarily immune.
