10. An apparatus for use in a safe, minimally-invasive, painless method of safely collecting and testing blood from a patient which comprises:
- a piercing pin mounting on a base;
a collapsible, telescoping cover having a cup-shaped top sealed at its bottom to the base;
a porous test disk containing dry reagents under the cup-shaped top; and
a reservoir containing a liquid for moistening the dry reagents disk, said reservoir being in an overcap which during storage is spaced from the top to keep the liquid separated from the dry reagents until immediately prior to use and which at time of use is placed over the top and used to moisten the dry reagents disk so that when a pressing force is exerted on the top with a finger, the telescoping cover will collapse permitting the finger to be pierced and blood or other fluids to be transferred onto said test disk.
