Specimen Type Describes the specimen type needed for testing

Whole blood

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.

Collection Container/Tube:

Preferred: Whatman Protein Saver 903

Acceptable: Ahlstrom 226 filter paper, Munktell filter paper, and dried blood spots from Supplemental Newborn Screening Card (Supply T493) or Postmortem Screening Card (Supply T525).

Specimen Volume: 2 blood spots

Collection Instructions:

1. Let blood dry on filter paper at room temperature in a horizontal position for 3 or more hours.

2. At least 1 spot should be complete, ie, unpunched.

3. Do not expose specimen to heat or direct sunlight.

4. Do not stack wet specimens.

5. Keep specimen dry.

Additional Information: Blood dried on filter paper containing heparin or EDTA is acceptable.

Forms: New York Clients-Informed consent is required. Please document on the request form or electronic order that a copy is on file. An Informed Consent for Genetic Testing (Supply T576) is available in Special Instructions.

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.
