Upon waking, collect your urine into the same container. Fill the container, and pass any additional urine into the toilet.

Saliva Collection (Only For Genomics Add-On Testing)
Night Before Collection - 

• Use your normal nightly routine of brushing and flossing of teeth, but do not use mouthwash

Morning Of Collection - 

• Specimen must be collected immediately upon rising. Do not practice normal oral hygiene routine, do not eat or drink anything other than water.

1. Keeping the packet intact, peel open the package labeled, “Sterile Cotton Tipped Applicator.” Only peel back the package far enough to remove the cotton swab applicator.
2. Remove one applicator. Avoid contact with the cotton tip.
3. Open your mouth widely and insert applicator. For at least 30 seconds, aggressively scrape the inside of your cheek using a back and forth, and up and down motion. Rotate the applicator several times, and swab between the cheek and gums. Avoid excessive saliva. Note: Follow these instructions carefully to ensure the swab collects a sufficient amount of cheek cells. If there is not enough DNA collected on the applicator, a recollection will be required.
REPEAT WITH SECOND SWAB
4. Allow swabs to air dry for 15-20 minutes, then replace them (swab first) into the swab applicator package.
5. Print Full name, collection date, and date of birth on specimen collection label. Place the specimen collection label on the envelope.
