Invitae's saliva sample collection kit provides the materials and instructions for collecting and stabilizing saliva specimens.
Before collecting a saliva sample the patient should not eat, drink, smoke, or chew gum for 30 minutes. Do not offer mother’s milk or formula to infants in the 30 minutes prior to sample collection. In addition, do not remove the plastic film from the funnel lid.
Sample collection from infants and young children can take time. It can be helpful to provide entertainment or distraction for the patient to improve their tolerance. While collection is not at all painful, it does involve the patient holding their mouth open for periods of time while a person collects their saliva.
- Place sponge in mouth, running along the cheek and the gums. Saliva often accumulates under the tongue, so swirling the sponge in this area can help with sample collection.
- Insert saturated sponge in V-notch of funnel and wring the saliva out, allowing the saliva to release into the tube.
- Repeat collection steps until saliva reaches the fill line.
- Close the lid tightly until you hear a loud click. Unscrew the funnel from the tube, place the small cap on tightly, and shake for a few seconds.
After completing the saliva donation, there are no special storage requirements for shipping the tube to Invitae. The saliva kit is stable at room temperature. For more information, please contact Client Services.
