How to take a sample


Spit a SMALL amount of saliva into the funnel. Lightly tap the base of the tube on a flat surface to allow saliva to flow into the tube. Make sure that the liquid (non-frothy) part of the saliva is between the lines, as shown in Figure 1.


Hold the tube vertically with one hand. Close the funnel cap with your other hand (see picture), pressing on it until you hear a click. The colored liquid in the cap will be poured into the tube and mixed with saliva. Make sure the cap is tight.


Hold the tube vertically. Unscrew the funnel from the tube.


Close the tube tightly with a small cap.


Shake the sealed tube for 10 seconds. Throw the funnel away or recycle it.
