Anti Streptococcal O Titre (ASOT) Blood Test

Measures antibodies to streptolysin O, a substance produced by group A streptococcus.

Measures

Antibodies to streptolysin O, a substance produced by group A streptococcus.

Why it matters

These antibodies indicate the immune system has encountered group A strep at some point. Levels rise after exposure and fall slowly over months.

Because the antibodies persist, a raised result indicates past exposure rather than current infection. That distinction matters and is exactly why the result needs a clinician.

Suits

People whose practitioner has specifically requested ASOT, usually as part of a defined investigation.

Your next step
