Anti-DNase B (Streptococcal) Antibodies Blood Test

An Anti-DNase B Antibodies Blood Test provides evidence of an existing or past streptococcal infection.

Description

ADNase B antibodies react against the exoenzyme desoxyribonuclease B produced by streptococci. The detection of these antibodies provides evidence of an existing or past streptococcal infection (rheumatic fever, scarlet fever, tonsillitis, glomerulonephritis, and others). The antibody reaction against streptococcal DNase B starts later than the antibody production against streptolysin O, but it can then be detected on a greater percentage of patients. An increase in the antistreptolysin concentration rarely occurs with skin infections, while a rise in the ADNase B titer can be observed.
