Specimen Type Describes the specimen type needed for testing
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.
Preferred: Whatman Protein Saver 903 Paper
Acceptable: Ahlstrom 226 filter paper, Munktell and Supplemental Newborn Screening Card (Supply T493)
Specimen Volume: 2 blood spots
1. An alternative blood collection option for a patient >1 year of age is fingerstick.

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 blood spot
