CH50 Blood Test - More Information
The CH50 test, also known as a CH50 blood test and total complement CH50 lab test, measures the CH50 blood level.
The CH50, or total complement activity, test measures the effectiveness of part of the immune system known as the complement system. The complement system helps other parts of the immune system attack invaders and clear out damaged cells. The complement system is made of proteins made in the liver.
The CH50 test may be low in the setting of a genetic mutation, liver or kidney issues, arthritis, SLE, and hemolytic anemia (red blood cell destruction). High CH50 levels may be seen in certain types of cancers and general inflammatory conditions and in diseases like leukemia and Hodgkin's.
To get a CH50 test near you, just order online and get your blood drawn at the Quest Diagnostics lab that you selected. Once your CH50 lab report is ready, it will be available for download. As can be seen on the sample CH50 lab results above, the total complement CH50 blood level will be reported as a number which can be compared against the reference range provided by the lab.
