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.
Provide a reason for referral and the specimen source with each specimen. The laboratory will not reject testing if this information is not provided, but appropriate testing and interpretation may be compromised or delayed.
Container/Tube: Sterile container
Specimen Volume: 25-50 mL
Collection Instructions: Collect specimen in a sterile syringe.
Additional Information: Advise Express Mail or equivalent, if not on courier service.
Forms: If not ordering electronically, complete, print, and send 1 of the following forms with the specimen:
Cytogenetics/AFP Congenital Disorders Request Form (Supply T238)
Hematopathology/Cytogenetics Test Request Form (T726) (www.mayomedicallaboratories.com/media/customer-service/forms/hematopathology-request-form.pdf)
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.
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
