Specimen Type Describes the specimen type validated 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.

Collect specimen into the same leak proof, sterile plastic collection vial until 3 g of meconium have been collected or until the first milk stool appears. Between collections, store specimen in a secure refrigerator. When at least 3 g of meconium has been collected, tightly screw on the cap of the collection vial and send specimen refrigerated.


Note: Specimens from different voiding may be pooled if necessary.

Specimen Minimum Volume The amount of sample necessary to provide a clinically relevant result as determined by the Laboratory.

0.7 g
