introducing a volume of blood into an enclosure of a blood-clotting mold device, the enclosure
being in the shape of a blister having a main body with a blister depression having a blister wall and a flat rim, sealed by a removable closure, the enclosure
comprises a blood clot supporting matrix, and wherein the blood clot supporting matrix comprises gauze held at its peripheral portions between the rim and the closure and having a central portion within the enclosure, and
comprises a coagulation initiator,
wherein at least one of the blister wall and closure is pierceable by needle and said introducing comprises piercing one of the blister wall or closure with a needle and injecting the blood therethrough;
maintaining the blood within the enclosure for a time sufficient to permit clotting of the blood to thereby obtain a blood clot;
removing said closure to open the enclosure; and
extracting the blood clot from the enclosure with said matrix.
