ASO Titer

You should get an ASO titer test if you develop joint pain or swelling, fever, chest pain, skin rash, or involuntary movements a few weeks after a sore throat or skin infection, which may suggest rheumatic fever. It is also recommended for dark or blood-tinged urine, facial swelling, or high blood pressure, which suggest kidney inflammation.

No special preparation or fasting is required for an ASO titer test. Inform your doctor about any recent sore throat or skin infection, and any antibiotics or steroids you have taken, as these can affect antibody levels. A repeat test after 2–4 weeks may be advised to check for rising levels.

No, fasting is not required for an ASO titer test. You can eat and drink normally before giving your sample, and the test can be done at any time of day. Inform your doctor about any recent throat or skin infections and antibiotic use, as these help interpret the results correctly.
