What is Antistreptolysin Titer?
The Antistreptolysin Titer (ASO titer) measures the amount of antibodies in the blood produced against streptolysin, a toxin made by group A streptococcal bacteria. This test helps in diagnosing a recent streptococcal infection, such as strep throat or scarlet fever.
Why should you have Antistreptolysin Titer tested?
Testing the ASO titer is useful for determining whether a recent infection with streptococcal bacteria might be the cause of symptoms such as a sore throat, fever, or more complex conditions like acute rheumatic fever or glomerulonephritis, a type of kidney disease.
What does it indicate?
An elevated ASO titer indicates a recent infection with streptococci. It helps physicians identify the cause of certain symptoms and can contribute to the diagnosis of post-streptococcal conditions.
What does a high Antistreptolysin Titer mean?
A high ASO titer suggests a recent or active infection with streptococci. It may indicate complications caused by the bacteria, such as rheumatic fever or glomerulonephritis, especially if there are no clear symptoms of strep throat.
What does a low Antistreptolysin Titer mean?
A low ASO titer suggests that there has been no recent streptococcal infection. It can also mean that an infection occurred longer ago, and the body has already reduced the antibodies.
Frequently asked questions
Answers to what people usually want to know.
How does it work from order to result?
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
How quickly can I get tested?
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
Do I need to book an appointment?
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.
