The collector pad is a 100% cotton-based, highly absorbent material, dimensioned to hold the amount of saliva needed to run the test successfully.
Three cues to tell you if you have collected enough saliva:
- The surfaces of the collector pad appear thoroughly wet and soaked.
- The collector pad has expanded - the thickness expands up to 25-30% when fully saturated. Observe and compare the collector pad before and after saliva collection.
- A thin coating of saliva on the surface of the pad indicates that it is fully saturated.
