PCR tests are more likely to detect small traces of virus than antigen tests. Your sample will usually be taken by a healthcare provider and transported to a laboratory for testing. It may take 2-3 days to receive the results.

Antigen tests are rapid tests that detect coronavirus protein spikes. They are more likely to detect the virus when someone is most infectious. However, positive results are very accurate and reliable. The results are in about 15-30 minutes.

Proctored PCR and antigen testing are available onsite by appointment only. However, as a community site, we are prioritizing those that are uninsured and underinsured. If you have insurance, we encourage individuals to seek COVID-19 services through their medical providers. Feel free to contact us at (510) 735-3222 for more information.

Self-test and at-home test kits are examples of antigen tests. You can:

• Buy self-tests (at-home tests) online or in pharmacies and retail stores. Private health insurance may reimburse the cost of purchasing self-tests. Visit FDA’s website for a list of authorized tests.
• Visit a community-based testing location, such as a pharmacy or health center near you. These locations may offer PCR or antigen tests, and provide low- or no-cost testing for everyone, including people without insurance. Free PCR or antigen tests may also be available through your local health department.
• Talk to a doctor or healthcare provider about other testing options that may be available to you.
• If you are a person with a disability, the Disability Information and Access Line can help you access a test or find a test location.

• Before and after you travel.

Higher-risk individuals include the elderly, those who live in congregate care facilities, those who have immunocompromising conditions, and that put them at higher risk for serious illness.

If you have tested positive or are developing symptoms, wear a mask and isolate immediately. Stay away from others until at least 24 hours after both symptoms are getting better overall, and you have not had a fever (and are not using fever-reducing medication).

Most people with COVID-19 have mild illness and can recover at home. You can treat symptoms with over-the-counter medicines, such as acetaminophen or ibuprofen, to help you feel better.

Medications are available to reduce symptoms and support recovery but must be taken within 5-7 days after symptoms onset. If you are positive, contact your primary care provider or access a telehealth visit through SesameCare by calling (888) 897-1244 or visiting their website.
