Test ID: FFRBC
Folate, RBC
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.
Draw 5 mL lavender-top (EDTA) or pink-top (K2 EDTA) tube(s), mix
well and transfer 1 mL EDTA blood to an amber vial (Supply T192)
to protect from light. Ship frozen.
Note: 1. Hematocrit (HCT) report value drawn within 24 hours of
Folate, RBC is required.
2. Protect from light during collection, storage and shipment.
3. Separate samples must be submitted when multiple tests
are ordered.
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
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
