Total complement activity (CH50 or CH100) may be ordered to look at the integrity of the entire classical complement pathway. This involves looking at the ability of the patient's serum to lyse antibody-coated sheep erythrocytes. We have retrospectively analyzed complement profiles data of eight aHUS patients under eculizumab from the International Registry of HUS/Thrombotic Thrombocytopenia Purpura, and calculated a novel marker “C3:CH50 ratio” by dividing C3 value by CH50 one for each sample during induction and maintenance periods.

If your complement system is compromised, then you will be more susceptible to infection. Normal values for C1q are 0. HSS Manual Ch. C3 and C4 are the complement components measured most often. The level of CH50 was relatively constant during the observation period in each individual patient. 67 (. The levels in the complement system may be low on account of hereditary reasons. We prospectively measured the complement activation products Ba, Bb, SC5b—9, and C4d, as well as the conventional complement determinants C3, C4, and CH50, during pregnancy in 14 patients with SLE and 10 women with preeclampsia. The intracellular, membrane-bound antigen has the capacity of inducing high levels of IgM and high levels of B1 cells. I don't know what this means- from some quick googling, low CH50 points to active lupus, where high CH50 can point to many things (acute inflammation, some cancers) but not specifically autoimmune.

The total hemolytic complement activity of CH50 and its fractions C3 and C4 was determined in the sera of 196 patients with carcinoma of the oral cavity, 172 patients with carcinoma of the uterine cervix, and 166 patients with breast cancer. In immune complex deposition disease, serum complement proteins are consumed and serum levels decrease. Another argument is that the observed intrafamilial disease concordance for SLE in combination with complement deficiency is extremely high. Complement levels that are too low or too high can cause problems. CH50 is similar with CRP, with a high sensitivity of inflammation.
