Abstract
There is disclosed apparatus for use in bleeding-time tests. The apparatus includes an envelope which has an internal hollow and is sealed at all sides and has an opening at one side or at one corner. The envelope contains a blotter member which is located in the hollow of the envelope and dimensioned so that a peripheral section of the blotter member extends from the opening. In this manner a user can move the blotter member with respect to the envelope to thereby change the section of the blotter member which extends from the opening. The apparatus and methods enable one to utilize different sections of the blotter while directing previous blotted blood sections into the internal hollow of the envelope thereby avoiding contact with the previously blotted sections.
