My kit came today!
Sorry about the blurry picture, above. I can't take another picture because I already mailed back the box. Basically, you spit into the funnel and fill the tube up to the black line. (You're not supposed to eat or drink anything for 30 minutes beforehand.) Then, you close the cap on the funnel. Inside that cap is some sort of clear fluid. By closing the cap, you puncture the container holding the clear fluid in the cap and it mixes with your saliva. (Does anyone know what that fluid could be?) Then, you twist off the funnel and twist on that blue cap. Finally, you mail the tube back to the lab and wait about a month.
