About ASOT
ASOT checks for antibodies your body produces after a streptococcal infection, most often a throat infection. It is commonly ordered when investigating conditions like rheumatic fever or certain kidney inflammations that can follow an untreated strep throat.
No fasting is required, and your report is ready the same day, helping your doctor confirm whether a recent illness was linked to a strep infection.
How to Prepare
- No fasting required.
- No special preparation needed before your blood draw.
