Book a Test- Anti DNase B

Anti-DNase B is a blood test used to diagnose and monitor infections caused by Group A Streptococcus (GAS), such as strep throat and rheumatic fever. The test measures the levels of antibodies against DNase B, an enzyme produced by GAS bacteria. When GAS bacteria infect the body, the immune system responds by producing antibodies against the bacteria's proteins, including DNase B. The anti-DNase B test detects these antibodies in the blood, which can indicate a current or past GAS infection. The test is often used to diagnose acute rheumatic fever, a complication of strep throat that can cause inflammation and damage to the heart valves. The test can also be used to monitor the effectiveness of treatment for GAS infections and to detect recurrent infections. A positive test result indicates the presence of antibodies against DNase B, which can confirm a GAS infection.
