Antibody tests check a sample of a person’s blood to look for antibodies to the virus that causes COVID-19. These antibodies are produced when someone has been infected, so a positive result from this test may indicate that the person was previously infected with the virus.

• It typically takes 1-3 weeks after infection to develop antibodies to the virus that causes COVID-19.
• This means an antibody test won’t necessarily tell you if you have a current infection. A viral test (PCR) should be taken to diagnose a current infection.
• We do not know yet if antibodies protect a person from getting COVID-19 again.
• Antibody tests are not as accurate as diagnostic tests and sometimes include “false positives."

Maricopa County has partnered with Valle del Sol to provide diagnostic PCR testing in communities across Maricopa County.  These events, funded through the CARES Act, are intended to add testing locations and options to those already available through the State of Arizona and some cities. 

Diagnostic testing is one way we can understand trends in how the virus is spreading in our community.  So why fund PCR tests instead of antibody tests?

Disease investigation and contact tracing are most effective when Public Health is quickly notified about an active infection.  That way, staff can reach out to a person while they’re still contagious to limit their contact with others.  This also allows Public Health to alert a COVID-positive person’s close contacts so they can watch for symptoms during the timeframe they may become ill and take steps to protect themselves and others.

Antibody tests do not provide Public Health data about active infections, making those tests less effective in managing disease spread.

With all the talk about COVID-19 and health care capacity, you may have put off your annual check-up or maybe you decided not to seek treatment for a medical condition or new health issue.  If that describes you, don’t delay any longer.  Many doctors and health clinics have virtual appointments available.  You can often talk to your doctor online, by phone, or through email, and then follow up in person if necessary.  As always, if you need emergency medical care, seek it immediately.  Emergency rooms are safe.

Businesses continue to adjust operations during the pandemic, and we want to say thank you to the store owners, entrepreneurs, restauranteurs, and business operators who have prioritized public health.  None of this is easy, and livelihoods are on the line.  We appreciate the way in which so many of you are thinking creatively and selflessly to serve the community.  Remember, if you need assistance, you can reach out through our business hotline (by dialing 2-1-1) or through our website.

Local businesses and non-profits (501(c)3) can get reimbursed for financial losses incurred during the pandemic through the expanded Maricopa County Small Business Relief Program!  The new application requirements make it easier for organizations to qualify and apply for a grant for up to $25,000.
