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.

Send specimen Monday, Tuesday, or Wednesday only.


For all specimens, patient history and requests should be clearly labeled with correct patient identifiers and pathology accession/case number. Collection date and patient date of birth are required. All specimens must be labeled with specimen type. The name and phone number of the ordering physician and a brief history are essential to achieve a consultation fully relevant to the ordering physician's needs. The Muscle Histochemistry Patient Information Sheet should accompany all specimens. Not to have this information may delay the specimen processing significantly.

Biopsies from different sites require separate orders and separate specimen vials.
