What is the CH 50 assay?
The CH 50 assay measures the complement activity of serum by assessing its ability to lyse sensitized red blood cells.
Why is complement activity important?
Complement activity is crucial for the immune response, helping to eliminate pathogens and damaged cells.
What materials are needed for the CH 50 assay?
You will need test serum, sensitized sheep red blood cells, buffered saline, and various tubes for dilutions.
How are serum samples diluted in the assay?
Serum samples are diluted in a series of twofold dilutions, starting from a one in eight dilution.
What does a high CH 50 value indicate?
A high CH 50 value indicates strong complement activity and a robust immune response.
Can the CH 50 assay be used for clinical diagnostics?
Yes, the CH 50 assay can help diagnose complement deficiencies and related immune disorders.
