The "Stabilize specimen & hold" test number is available for all situations when a specimen must be drawn before the final decision about testing is complete. The specimen may be sent to Allele Diagnostics and stabilized in our laboratory while final decisions are made. For specimens that have testing authorized to proceed at our laboratory within 1 month of specimen receipt, no additional fees will be incurred by utilizing the "stabilize & hold" option. For specimens that do not have testing proceed at our laboratory within 1 month of specimen receipt, a fee will be incurred for the specimen stabilization procedures. If testing authorized to proceed within 3 months of specimen receipt but after the fee has been incurred, the fee will be deducted from testing performed.

Samples that are not utilized for testing will be retained for up to 12 months before being destroyed unless otherwise stated in disposal guidelines set forth by the state in which the ordering physician practices.
