The Anti Dnase B test detects the presence of Anti-Dnase B antibodies in the blood, which are often elevated in individuals who have had a recent streptococcal infection. This test is particularly useful in diagnosing and monitoring conditions such as rheumatic fever and post-streptococcal glomerulonephritis. A 1 ml serum specimen is required for this test, providing results in 1 day. Priced at 1200 THB, it helps in confirming the presence of a recent streptococcal infection and related autoimmune response.
