Fulgent Test Description

The Fulgent Coronavirus Disease (COVID-19) RT-PCR test is a reverse transcription polymerase chain reaction test to detect SARS-CoV-2, the virus that causes COVID-19. This method is also called a nucleic acid amplification test (NAAT).

The SARS-CoV-2 primer and probe sets are designed to detect RNA from 2019-nCoV in specimens from patients who meet CDC 2019-nCoV clinical criteria. Primer and probe set sequences are based on CDC recommended guidelines that identify two known distinct regions within the SARS-CoV-2 genome. Amplification of both targets will signify a positive result; amplification of one of two targets will signify an indeterminate (inconclusive) result; and no amplification of either target, but amplification of internal control, will signify a negative result. Inconclusive results will require a new sample for testing.

* This test has been authorized by the FDA under an Emergency Use Authorization (EUA). This means that while the laboratory performing this test has validation data to support offering this test, it has not been approved or cleared by the FDA. This test has only been authorized by the FDA for detection of nucleic acid from SARS-CoV-2 (i.e., the COVID-19 virus), and not for any other virus or pathogen. It is only authorized during the duration of the COVID-19 emergency declaration by federal regulators under Section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner. Please see the Patient Fact Sheet and the Healthcare Provider Fact Sheet for additional information. Additional information can be found on the FDA's website.

*Going forward, COVID-19 testing will no longer be held at Senior Coastsiders. You can still sign up for testing at the Ted Adcock Community Center, which is available every Monday.*

After a Test: What’s Next?

Most results are returned in 72 hours.

If your first COVID test is negative, you should get tested again if you:

  • Are concerned about possible exposure
  • Have spent time with people outside your household
  • Have had exposure to someone with confirmed or possible COVID-19
  • Have symptoms
  • Work in a congregate setting like a nursing home or shelter are planning to visit someone at high risk for severe COVID-19 illness

If you test positive for COVID-19, a contact tracer with San Mateo County Health will contact you. Certain support services may be available for those who qualify.

If you do test positive, view home isolation instructions in multiple languages.

Why is COVID-19 testing important?

The results of your COVID-19 test, along with other information, can help you and your health care provider make informed decisions about your care.

  • Being tested for COVID-19 may help limit the spread of COVID-19 to your family and others in your community.
  • Widespread testing also helps inform the public health response, allowing health care professionals to quickly discover patterns and respond to outbreaks.
  • Testing also plays a key role in determining what sectors of the economy are permitted to open – and help all of us get back to work, to school and to enjoy everyday life safely.
  • Widespread testing along with a low rate of positive tests helps our community comeback from COVID-19.
