However, this test can …

WebThe saline agglutination test is a useful method to identify RBC agglutination, which should not be present in a normal patient. This test can be performed by mixing 1 part RBCs with 4 parts saline to help disperse strong rouleaux that can cause false-positive results. WebThe direct Coombs' test is also known as direct antiglobulin test and is used to detect antibodies and complement on the surface of erythrocytes when the anti-erythrocyte antibody strength or concentration is too low to cause spontaneous agglutination (so-called subagglutinating titer).

WebAgglutination: Examination of blood smears may reveal microscopic autoagglutination (clumping) of RBCs.
