Strep throat - anti-DNase B test; Antideoxyribonuclease B titer; ADN-B test

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 ASLO titer test, more than 90% of past streptococcal infections can be correctly identified.

Blood test

Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.
