ASO antibody blood test (antistreptolysin O)

ASO testing identifies streptococcal antibodies that may indicate infection-related inflammation. Staying on top of infections supports uninterrupted vitality.

Doctor's Assessment Included

ASTO (Antistreptolysin O): what this test measures

This test measures the level of ASO antibodies in your blood. Rising titres suggest a recent streptococcal infection, while declining titres indicate recovery.

ASTO (Antistreptolysin O): why this value matters

ASO testing helps identify complications from streptococcal infections, such as rheumatic fever or glomerulonephritis. Early detection supports timely medical intervention. Consult your healthcare provider for interpretation.

ASTO (Antistreptolysin O): when is testing worthwhile?

Testing may be recommended after a streptococcal throat infection, or if you develop symptoms such as joint pain, skin rashes, or kidney problems following a sore throat.

ASTO (Antistreptolysin O): symptoms of a high or low value

Low Levels

Low ASO levels are normal and indicate no recent streptococcal infection. No symptoms are associated with low levels.

High Levels

Elevated ASO may be associated with post-streptococcal complications including joint pain, fever, skin rash, and kidney inflammation. Persistent elevation warrants medical follow-up.

ASTO (Antistreptolysin O): lifestyle and this value

Seek prompt treatment for streptococcal throat infections. Good hand hygiene and avoiding close contact with infected individuals can help prevent streptococcal infections.

ASTO (Antistreptolysin O): frequently asked questions

How long do ASO levels stay elevated?

ASO levels typically peak 3-5 weeks after infection and may remain elevated for several months. Your healthcare provider can monitor the trend over time.

Can ASO be elevated without symptoms?

Yes, ASO may be elevated after a mild streptococcal infection without noticeable complications. Follow-up testing helps determine if levels are declining normally.

What is rheumatic fever?

Rheumatic fever is a rare inflammatory condition that can develop after untreated streptococcal infection. It can affect the heart, joints, and nervous system. Consult your healthcare provider for more information.
