Anti-DNase or Anti-Deoxyribonuclease B is a type of blood test which is used to check the presence of antibodies to a protein produced when affected by group A beta-hemolytic streptococcus. This is a bacteria that is responsible for many infections affecting the throat, impetigo, and cellulitis and responds to antibiotic treatment. 

The test is usually performed to identify the infection and maybe past infection related to streptococcus. If you had a past history of infection then you might face some issues in the kidney for the same. 

According to the Best diagnostic center in Jalandhar, if the strep A infection is not diagnosed or not treated well, it leads to some complications like acute rheumatism (rheumatic fever) or glomerulonephritis (kidney inflammation). When the test is used together with the ASLO titer test, more than 90% of streptococcal infections can be identified accurately.

The test is usually performed with the blood sample drawn from hand. 


A negative test for the antibodies is normal. Some cases can have low concentrations of these antibodies but they do not have the infection around the time. This makes the values differ from each other in different age groups, which are:

  • Adults – Less than 85 units/milliliter (mL)
  • School-age – Less than 170 units/mL
  • Preschool children – Less than 60 units/mL

Normal value ranges vary slightly in different labs as per the Blood sample collection in Jalandhar as the labs use different measurements or test different specimens. 

Increased levels of DNase B levels can stipulate the exposure of the body to group A beta-hemolytic streptococcus. 

Anti-DNase B titers remain uplifted longer than ASO titers and are more reliable than the then ASO to confirm the presence of processing streptococcal skin infections as well. 

The best diagnostic center in Jalandhar has many other tests to check the details and root cause of the issues causing discomfort.
