Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
If appropriate, confirmation testing will be performed at no additional charge.
Specimen Type Describes the specimen type validated for testing
Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Specimen Type: Umbilical Cord Tissue
Container/Tube: Plastic, preservative-free container
Specimen Volume: 10 grams
Collection Instructions: Ensure sample is not exposed to ethanol-containing vapors or liquids during collection and storage. Collect at least 6 inches of umbilical cord (approximately the length of an adult hand). Drain and discard any blood. Rinse the exterior of the cord segment with normal saline or sterile water.
