Autoimmune diseases often lead to high CH50 levels. This indicates an active complement system, which is part of the body’s defense against pathogens. However, in autoimmune disorders, this system mistakenly attacks healthy tissues. Lupus erythematosus and rheumatoid arthritis are prime examples.
What does it mean if your Complement, Total (CH50) result is too high? Increased levels of complement may indicate: - Acute-phase immune response. - Cancer. - Ulcerative colitis. - Heart attack (acute myocardial infarction) - Sarcoidosis.
Increased CH50 values means that their complement is hyperfunctional relative to normal, and this may be seen in cancer or ulcerative colitis [citation needed]. One can interpret the CH50 value along with the individual's complement factor values to help determine the etiology.
CH 50 (total hemolytic complement assay) measures the ability of the serum test sample to lyse 50% of sheep RBCs coated with rabbit immunoglobulin, reflecting the functional status of the...
A CH50 test (sometimes called CH100 or a total complement test) measures the total activity and levels of all the major complement proteins. If the CH50 level is not normal, each of the nine complement levels can be measured individually to find out which one is abnormal.
Complement proteins may be measured individually or together. C3 and C4 proteins are the most commonly tested individual complement proteins. A CH50 test (sometimes called CH100) measures the amount and activity of all the major complement proteins.
