ANTIDNASE-B (DNB)

The anti-DNase B test measures the level of antibodies against DNase B, an enzyme produced by Group A Streptococcus bacteria. Elevated levels of anti-DNase B antibodies indicate a recent streptococcal infection. This test is used to diagnose and monitor complications of streptococcal infections, such as rheumatic fever and glomerulonephritis. A positive anti-DNase B test suggests that the immune system has responded to a streptococcal infection. It is valuable for guiding treatment decisions and monitoring the effectiveness of therapy in preventing complications related to streptococcal infections.
