COVID-19 Testing
Who Should Get Tested

If you are experiencing any symptoms consistent with COVID-19, you should immediately contact your healthcare provider to discuss your symptoms and be directed to testing as appropriate. 

Please keep in mind that most people will have mild illness and should recover at home without medical care. Please be familiar with what to do if you are sick.  

If you believe you had symptoms consistent with COVID-19 in the past, but were unable to get tested at the time, you may be able to get an serology (antibody) tests to help you confirm. 

Types of Tests

There are two types of tests available for COVID-19. 

Viral Detection Tests

Viral detection testing is used to detect current infection. It is also referred to as a polymerase chain reaction (PCR) test, molecular test, or nucleic acid amplification test (NAAT). It is a diagnostic test that finds genetic material from SARS-CoV-2, the virus which causes COVID-19. 

Only viral detection tests can accurately diagnose COVID-19. 

Serologic (Antibody) Tests

Serology testing, or antibody testing, detects the presence of SARS-CoV-2 antibodies in your body from a previous infection. Because it takes 1-3 weeks after an infection for your body to create antibodies, this type of testing cannot detect if you have a current infection. 

There are also two types of serologic tests: 

Rapid serology (antibody) tests use a small, finger-stick blood sample, but at this time, many of the rapid tests have not been fully validated and the results of these tests are inconclusive. 

Laboratory serology (antibody) tests use venipuncture, a larger blood sample usually taken from the arm, and while this is a much more reliable test for detecting SARS-CoV-2 antibodies, there are still many unknowns about interpreting the results. 

Some points to keep in mind about antibody tests:
  • A negative serology (antibody) test means you have not developed an immune response to COVID-19, but it does not necessarily mean that you didn't have a COVID-19 infection. It can take 1-3 weeks to develop antibodies following an infection. 
  • You may not be protected from COVID-19 even if you have antibodies. We don't know yet if having antibodies can protect against getting infected again or how long protection could last. 
  • It's unknown if these tests are sensitive to detecting antibodies only to SARS-CoV-2 or if they are detecting antibodies to other coronaviruses. 
  • It is important that even after a serology (antibody) test comes back positive, you continue to take precautions recommended for the general public. 
Where to Get Tested

Local Testing

Most healthcare providers offer COVID-19 testing to patients who meet testing criteria. If you need to be tested for COVID-19, start by reaching out to your normal healthcare provider.

Some healthcare providers are using commercial labs for serology (antibody) testing. Please call your healthcare provider to confirm. Redwood Urgent Care is also offering serology (antibody) testing at their Eureka site. 

On May 13, Del Norte OES announced that a local State-sponsored testing site will be coming soon to Del Norte County. The details of the testing site are still being worked out and more information is to come. 

CA COVID-19 Testing Site
