Abstract
An improved blood sample apparatus having a capillary channel formed in a basal element and enclosed with a transparent overlay to create a capillary tube. A chamber for receiving a sample of blood is formed in the basal element at one end of the capillary channel. A blotter is placed in the chamber to receive the sample of blood. An overflow reservoir is formed perpendicularly to the capillary tube and receives surplus blood in excess of that needed to fill the capillary tube. A scale adjacent the capillary tube provides an automatic reading of the hematocrit. The transparent overlay sealingly encloses the sample of blood inside the hematocrit apparatus. The transparent overlay also includes a writing surface and a machine-readable indicia.
