It’s crucial to let the swabs dry fully before sealing them in the specimen envelope. The goal of the sample collection is to capture cheek cells, not saliva. If the swabs are too wet, it can cause the test to fail.
When swabs are not completely dry before sealing, moisture can get trapped inside the envelope. This leads to the growth of mold and bacteria during shipping, which can damage the DNA and make the test results invalid.
Why Following Drying Instructions Is Crucial #
Important: The laboratory can detect if the drying instructions were not followed. If the swabs are still damp, a note will be added to your file.
If your test fails due to damp swabs, you may need to collect new samples and pay a recollection fee.
