February 1, 2022 Update

Please note that the Lab Service Center is experiencing extremely high volumes of registrations with minimal staff.  There will be service delays in calls, supply fulfillment, and registrations. If requesting supplies please give ample time. The TAT for Distribution Services is 5-7 business days.

The CHLA Lab accepts in-office saliva specimen collections for SARS-CoV-2 RT PCR viral testing. Office collected saliva specimens should be shipped/couriered to the CHLA laboratory and not dropped off at the CHLA drive-through testing site. As a reminder, CHLA’s Lab does not accept 3rd party billing for patients over the age of 21. To bill for these services, the CHLA Laboratory Service Center can set up a contract account for the Care Network practice. Patients and staff are advised to pay the office directly and the CHLA laboratory will send the office a monthly invoice. To set up a contract, please complete the Facility Contract Set Up Form and email it to


For more information, call the Laboratory Call Center at 877-543-9522.


Please note that the maximum courier range from the CHLA Main Campus is 25 miles. Please also note that since we do not run saliva overnight, the turn-around time is 48 - 72 hours.

Testing criteria have been developed with Infectious Disease faculty and the Infection Control and Prevention team at CHLA.  


Asymptomatic patients should be tested if they are medically fragile (e.g. severe asthma, congenital immunodeficiency, poorly controlled asthma that leads to frequent urgent care or ED visits) AND have been exposed to someone in their household who has tested positive


Symptomatic patients (URI, fever, feeling ill, diarrhea) should be tested if test results would have implications for clinical management. Testing is indicated if they meet one of the following:

  • Patient has unrelated developing illness that would likely lead to hospital admission in the next week

  • Patient is medically fragile (e.g. severe asthma, congenital immunodeficiency, poorly controlled asthma that leads to frequent urgent care or ED visits)

  • Patient lives or spends substantial time with a medically fragile individual whereby testing positive would lead to a change in social distancing or living arrangement


Billing for patients under 21:

  • Please make sure that patients under 21 provide their insurance card for billing, along with the “Clinical Requisition Form” found here.

  • Please note that HMO insurance is not accepted

Billing for patients over 21:

  • Please note that insurance is not accepted for patients over 21. The referring practice needs to have a contract account set up with CHLA for billing purposes.
