The saliva collection kit includes a return test tube containing a stabilizer. Once you have collected the sample, the stabilizer will be added immediately to stabilize your DNA sample and prevent potential bacterial contamination.
Samples mixed with stabilizers can be stored for a minimum of 3 months over a wide temperature range (-4ºF to 122ºF or -20ºC to 50ºC). Unused kits also remains stable even when exposed to temperatures within this range during shipping or storage. We recommend returning the sample to our lab at your earliest convenience after you have completed sample collection.
