AdministratorWhat does Anti-DNase B do?
Anti-DNase B is a blood test to look for antibodies to a substance (protein) produced by group A streptococcus. This is the bacteria that cause strep throat. When used together with the ASO titer test, more than 90% of past streptococcal infections can be correctly identified.
What does Streptozyme test for?
Aid in the diagnosis of current or previous group A streptococcal infections. Screening for antibodies to streptococcal antigens NADase, DNAase, streptokinase (ASK), streptolysin O (ASO) and hyaluronidase (AH): Positive test titered to 1:800; endpoint beyond 1:800 reported as > 1:800.
What is the positive result for Anti-DNase B testing?
Elevated or rising antibody titers of anti-DNase or ASO means that it is likely you had a recent strep infection. If your have signs and symptoms of rheumatic fever or glomerulonephritis, an elevated anti-DNase B and/or ASO titer can help confirm the diagnosis.
What two tests can be used to distinguish Streptococcus pyogenes from other members of the streptococci?
Bacitracin susceptibility Streptococcus pyogenes can be differentiated from other non-group A β-hemolytic streptococci by their increased sensitivity to bacitracin. The bacitracin test, along with the Lancefield antigen A test, is used for greater specificity in the identification of S.
Is Streptococcus DNase positive or negative?
Some studies suggest that up to 85% of patients with acute rheumatic fever from group A strep infection will be positive for ASO titers, leaving 15% of patients having been diagnosed with rheumatic fever negative for ASO titers….

What are the types of antibodies that are detected in Streptozyme?
The streptococcal antibodies measured include the following:
- Antistreptolysin (ASO)
- Antihyaluronidase (AHase)
- Antistreptokinase (ASKase)
- Antinicotinamide-adenine dinucleotidase (anti-NAD)
- Anti-DNAse B antibodies.
What is a normal ASO titer levels?
Generally, an ASO test value below 200 is considered normal. In children under the age of 5, the test value should be less than 100. Results will vary by laboratory. If your results show that you have an elevated ASO value, you may have a post-streptococcal complication.
What is anti DNase titer?
Antideoxyribonuclease B titer; ADN-B test. Anti-DNase B is a blood test to look for antibodies to a substance produced by Group A Streptococcus. This is the bacteria that causes strep throat. When used together with the ASLO titer test , more than 90% of past streptococcal infections can be correctly identified.
