(an'tē-strep-tol'i-sin), Avoid the mispronunciation antistreptoly'sin.
An antibody that inhibits or prevents the effects of streptolysin O elaborated by group A streptococci; the amount of antistreptolysin in the serum is frequently increased during and after streptococcal disease, and comparative titers may aid a diagnosis and prognosis.

In addition to this antistreptolysin O and anti-DNase B titres were elevated.
Other markers, such as amylase, antistreptolysin O, cholesterol, IgA, IgM, and transferrin, demonstrated the opposite pattern; that is, values were very low in the neonatal period and increased after 14 days.

We diagnosed guttate psoriasis in this patient based on her history and physical exam, a throat culture that was positive for group A beta-hemolytic streptococci, and blood work that showed an elevated antistreptolysin O titer.
Similarly, the supplement-only group showed the greatest improvement in the inflammatory blood markers C-reactive protein and antistreptolysin O (ASO).
Beginning on December 20, 2007, all patients with newly diagnosed EN were recommended to undergo acute sera testing, erythrocyte sedimentation rate (ESR) testing, chest radiograph, tuberculin skin test (TST), and testing for group A streptococcus (GAS) infection (via antistreptolysin O titer [ASO] and throat swab for GAS rapid antigen detection test [RADT]).
