Erycard Blood Typing

Easily determine blood type.

A small amount of blood is applied to a series of wells containing lyophilized blood typing antibodies, followed by the addition of a wash buffer that flows across each well. Red blood cells that agglutinate in the presence of a particular antibody will not be rinsed from the sample well and the well will remain red, indicating a positive result. Red blood cells that have not undergone agglutination will be rinsed from the well and the well will revert to white, indicating a negative result. Each card contains a negative control well to ensure accurate results.
