Measures properdin and factor B blood levels to assess alternative complement pathway function and immune activity.
This test measures levels of properdin and complement factor B in the blood. These proteins are part of the alternative complement pathway. They help the immune system tag and clear microbes and damaged cells. Proper amounts are needed for fast, effective defense. Abnormal levels can point to inherited complement problems, severe infections, autoimmune conditions, or complement-driven kidney disease. Doctors use these results to investigate recurrent infections, unexplained inflammation, or unusual kidney problems. Tests also help monitor response to treatments that target the complement system. Results are interpreted with other complement tests and clinical information.
No special preparation is required.
The Properdin Factor B test evaluates various parameters related to the different components. Here are the main parameters that are checked in the test:
Properdin Factor B tests are often ordered as part of a complement panel when doctors suspect innate immune problems. They are requested for recurrent or severe infections, unexplained inflammation, atypical kidney disease, or to monitor complement-related therapy. Abnormal results may come from inherited complement deficiencies, active infections, autoimmune disease, or medication effects. A family history of recurrent infections or complement disorders makes this testing more important.
