Thanks for providing more information.
A high count on the CH50 test means that your total complement system (part of the immune system) is hyperactive that goes along with an overactive immune disease and increased in infection.
Typically, other tests that are more specific for the suspected disease are performed first. C3 and C4 are the most commonly measured complement components.
And as C3 and C4 are normal in your case so slightly raised CH50 is not significant.
However usually low levels of CH50 are seen in Hereditary angioedema.
The increase or decrease in the complement levels assessed by the Complement CH50 test is not always an accurate indicator of what the exact problem is.
However, this test enables a doctor to determine if the immune system is involved with the ailment in any way.
So further a clinical corelation is required in your case.
I suggest you to consult your doctor as well.
Hope this helps.
