How to collect your sample
Collect from one side

Remove the collector from its package without touching the sponge.
Gently rub back and forth along your lower gums 10 times. Avoid the teeth if possible.
Collect from the other side

Repeat on the opposite side: gently rub back and forth along the lower gums 10 more times.
Open the tube

Keep the tube upright to prevent spills. Unscrew its blue cap without touching the sponge.
Reverse the cap and seal

Flip the cap over so the sponge goes into the tube. Screw the cap on tightly.
Shake to mix

Turn the sealed tube upside down, then shake it vigorously 10 times.
Bag your sample

Place the tube in the provided specimen bag.
Pack your sample

Place the specimen bag and tube in the return mailer.
