Step 1: Swab the inner cheek

• Swab inside the cheek with medium pressure for twenty (20) seconds.

• You are collecting skin cells, not just saliva. Use enough pressure to ensure you gain cells without harming the individual.

Step 2: Seal inside a standard sized paper envelope

• Place the single cotton swab into a standard envelope.
• Do NOT use plastic bags.
• Seal the envelope with tape. Please don't lick the envelope, as it can affect the DNA sample.
