Complement Hemolytic Activity Assay

Medical Condition:
Complement Hemolytic Activity Assay

Usual screening assay for complement. Dilutions of the serum to be tested are added to antibody-coated erythrocytes and the percentage of lysis is measured. The values are expressed by CH50, hemolytic complement units per milliliter, which is the dilution of serum required to lyse 50 percent of the erythrocytes in the assay.
