Laboratory

Collections for most samples will end at 3:30 p.m. on the last duty day of the week.  This is to ensure sample stability when shipped with the courier service transport.

Prepare For Your Visit

To provide the best care and value during your visit, we encourage communication with your healthcare provider to determine in your labs require any special preparation, such as fasting.  Additionally, you are encouraged to ask clarifying questions about your lab visit and if it specifically requires blood or urine collection.
 
Laboratory wait times may range more than two hours depending on factors such as time of day and volume of patients.  Wait times usually decrease after 12 p.m.  Patients receiving routine and non-fasting labs are encouraged to come after 12 p.m.
 
Off base lab requests will be accepted for active-duty service members only.  All other patients with off base requests need to have labs performed at an alternate collection site.  Labs ordered by JBSA healthcare providers can be collected at the Randolph Laboratory.
