Specimen preferred to arrive within 96 hours of collection.
Patient Preparation: A previous bone marrow transplant from an allogenic donor will interfere with testing. Call 800-533-1710 for instructions for testing patients who have received a bone marrow transplant.
Collection Instructions:
Whole Blood:
1. Invert several times to mix blood.
2. Send whole blood specimen in original tube. Do not aliquot.
Additional Information:
1. Specimens are preferred to be received within 4 days of
collection. Extraction will be attempted for specimens received
after 4 days, and DNA yield will be evaluated to determine if
testing may proceed.
2. To ensure minimum volume and concentration of DNA is met,
the requested volume must be submitted. Testing may be
canceled if DNA requirements are inadequate.
Saliva:
1. Collect and send specimen per kit instructions.
2. Patient should not eat, drink, smoke or chew gum 30 minutes prior to collection.
Additional information: Saliva specimens are acceptable but
not recommended. Due to lower quantity/quality of DNA yielded
from saliva, some aspects of the test may not perform as well as
DNA extracted from a whole blood sample. When applicable,
specific gene regions that were unable to be interrogated will be
noted in the report. Alternatively, additional specimen may be
required to complete testing.
