There are cases where indirect typing is not required:

It is the method of choice for rapid or bedside typing, commonly seen used in mass blood donation and medical mission. Used in Direct/forward typing procedure.

It is the method of choice for routine typing. Used in Direct/forward typing and Indirect typing procedure.

Red blood cell clumping; RBCs form clumps and clumping indicates the presence of LATTICE formation o commonly observed positive reaction in blood typing

It is a strong hemolytic reaction and strong agglutination reaction

The cross-bridging or cross-linking of antibodies adjacent to the antigen.

A red cell destruction; indication of hemolytic reaction is the release of hemoglobin which would change the serum/anti-sera color into clear red or clear pink

A patient has no reaction in both Anti-A and Anti-B.

A patient has reactions in both Anti-A and Anti-B.
