Question

Quizplus · Accepted Answer

Complement fixation tests involve the use of red blood cells as indicators. In these tests, the absence of hemolysis indicates that the complement system has been fixed (used up) by an antigen-antibody reaction elsewhere in the test system, suggesting a positive reaction. Hemolysis occurs when there is no antigen-antibody reaction to consume the complement, indicating a negative result.
