This instructional video shows parents in the DDD study how to take a saliva sample from their child using the Oragene sample collection kit and sponge. Parents also need to provide saliva samples by spitting into additional sample kits The samples then need to be sent off for analysis in the packaging provided with the sample kits. Each sample tube should be sealed in its own individual specimen pouch (with absorbent pad included), but samples can be sent together in the same envelope.
