What is an ASO test and how is it used to detect a strep infection? Antistreptolysin O (ASO) is a blood test used to help diagnose a current or past infection with group A strep (Streptococcus pyogenes). It detects antibodies to streptolysin O, one of the many strep antigens.

How do you treat ASO titre positive?

In most cases, penicillin is used to treat patients with increased levels of ASO titre.

How long does an ASO titer stay elevated?

Antistreptolysin-O Titer Antibodies are produced approximately a week to a month after the initial strep infection. ASO levels peak at approximately 4 to 6 weeks after the illness and then taper off but may remain at detectible levels for several months after the strep infection has resolved.
