ID-MICRO TYPING SYSTEM

The gel test employs the principle of controlled centrifugation of red blood cells through a dextran-acrylamide gel and appropriate reagent predispensed in a specially designed microtube.  Measured volumes of serum or plasma and/or red blood cells are dispensed into the reaction chamber of the microtube.  The card is incubated, then centrifuged.  Agglutinated red blood cells become trapped in or above the gel.  Unagglutinated red blood cells travel through the gel particles and form a pellet at the bottom of the microtube.
