Test ID: FADMK
ADmark Phospho-Tau/Total-Tau/Ab42 CSF Analysis & Interpretation (Symptomatic)
Specimen Type
Describes the specimen type needed for testing
CSF
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.
2 mL CSF in a polypropylene transfer tube, shipped frozen.
Note: Collection date is required.
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
