Types of tests
Two types of COVID-19 tests are available: Diagnostic tests and antibody tests.
A diagnostic test can show if you have an active coronavirus infection. Currently there are two types of diagnostic tests: viral PCR tests that detect the virus’s genetic material, and antigen tests that detect specific proteins on the surface of the virus. Testing sites listed on this page use viral PCR tests.
Antigen tests usually provide results faster than viral PCR tests at lower cost, but have a higher chance of missing an active infection. Antigen tests are used on people suspected of having COVID-19 within 5-12 days of symptoms appearing.
Antibody tests detect past infections. They can determine if you are a good candidate to donate blood plasma. It can take 1-3 weeks after infection for your body to make antibodies.
You can find locations for both viral PCR and antibody tests on the COVID-19 Testing Sites in California map.
Cost for testing
There are no out-of-pocket costs for medically-necessary testing. If you have medical insurance, OptumServe will bill your insurance company. If you’re uninsured, the government pays for your test.
Who can get tested
California’s testing capacity and turnaround time have improved. As a result, until further notice, all necessary testing requests will have equal priority.
When demand for tests exceeds capacity, testing will be prioritized in accordance with CDPH COVID-19 Testing Guidance.
The COVID-19 Testing Task Force is working to ensure that Californians have access to tests, and laboratories have capacity to meet demand.

California has partnered with OptumServe to provide free, confidential testing statewide. Tests are available for everyone, including underserved communities and individuals who are at high risk.
