Test ID: TREGS
T-Cell Subsets, Regulatory (Tregs)
Specimen Type 
Describes the specimen type needed for testing
Whole Blood EDTA
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Send specimen Monday through Thursday only. Specimen must arrive within 24 hours of draw and by 10 a.m. on Friday. Draw and package specimen as close to shipping time as possible. Ship specimen overnight.
Container/Tube: Lavender top (EDTA)
Specimen Volume: 3 mL
Collection Instructions: Send specimen in original tube. Do not aliquot.
Additional Information:
1. Ordering physician's name and phone number are required.
2. For serial monitoring, we recommend that specimen draws be performed at the same time of day.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
1 mL
