Test kit whereby the sponge portion of kit is used to swab saliva. The saliva is then extracted from sponge by either squeezing it out or through the use of a centrifuge. The sponge portion of the kit is attached to a collection container when used in the centrifuge. A filter can be placed between these two portions of the kit to filter out only substances of certain molecular weights and to clean saliva. When the saliva is collected by squeezing, the sponge is placed in soft walled vial that is squeezed to extract saliva. After extracted from the sponge, the collected saliva can be removed from kit by twisting off cap. This test kit can be used for, but not limited to, testing for HIV antibodies, hepatitis and drugs.
