RT-PCR COVID-19 Testing?


********** NOTICE ***********

All appointments made for Saturday ( 01/08/2022 ) and ( 01/09/2022 ) have been cancelled.

We are currently experiencing supply chain shortage in testing materials due to recent high testing demand and are unable to take on as many appointments as we'd like.

We apologize for the inconvenience.

Please stay tuned for future appointments.


Sierra Bio Lab provides RT-PCR testing performed to detect Covid-19 virus via nasal-pharynx swab according to CDC protocol. While we offer rapid COVID-19 test, they are not accurate, and the results are not for traveling purposes.

If this is for traveling purposes, please arrive within 3 days before your departure date to be tested and make sure you have your passport upon arrival at the testing center.
