What Is Ah50

This assay is a screening test for complement abnormalities in the alternative pathway. The alternative complement

What is AH50 and CH50?

Absent complement alternative pathway (AH50) in the presence of a normal total hemolytic complement (CH50) suggests an alternative pathway component deficiency. Normal AH50 with absent CH50 suggests an early (C1, C2, C4) classic pathway deficiency.

What does CH50 stand for?

Total hemolytic complement (CH50) is the best functional assay of the complete complement sequence. The traditional method for measuring total complement activity in serum is the CH50 test, which is a measure of total complement activity.
