For those traveling from the San Diego area: We strongly recommend using US Specialty Labs in Carmel Valley, as they are extremely reliable, professional, fast, easy, and their test results contain the necessary components (doc signature, company stamp). You make an appointment online for the RT-PCR Covid test (cannot accept the rapid tests or antigen tests) at usspecialtylabs.com and you would select the $65 test, not the $150 International Travel test. They offer a Rush processing fee of $35 if you prefer to be extra cautious, though their turnaround time is usually good.
