ADNase-B: Normal, High

ADNase-B, or ADB, measures the antibodies associated with the bacteria group A streptococcus, in order to find if there had been a prior strep infection with them.

Refence Value:

Adults: 0 to 85 units/milliliter (mL)

School-age children: 0 to 170 units/mL

Preschool children: 0 to 60 units/mL

What Do the Results Tell?

A normal result is negative. It indicates that you most likely haven’t had a recent strep infection.

A high result is abnormal. If your result is above the reference range, you may have had a recent strep infection.
