What is the purpose of this test?
The Anti-Streptolysin O Antibody (ASO) Blood Test is a medical test that measures ASO antibodies in the blood. These antibodies fight a streptococcal infection caused by a bacteria called Streptococcus. This infection can cause illnesses like strep throat, scarlet fever, and rheumatic fever.
Doctors use the ASO test to diagnose and monitor streptococcal infections. If a patient has a streptococcal infection, their body produces ASO antibodies to fight it. The ASO test can detect a current or previous infection. It can also check if the treatment for streptococcal infections, like antibiotics, is working. The ASO test is important because it helps healthcare professionals determine if a patient has a streptococcal infection and if the treatment is working. The test is straightforward and can provide valuable information to help diagnose and treat patients.
Who would benefit from this test?
This Anti-Streptolysin O Antibody (ASO) Blood Test may be beneficial for individuals who:
- Have symptoms of a streptococcal infection, such as sore throat, fever, and difficulty swallowing
- Have a history of rheumatic fever or glomerulonephritis
- Have a family history of rheumatic fever or glomerulonephritis
- Have been exposed to someone with a streptococcal infection, especially if they have a weakened immune system
- Have had a previous positive ASO test and need to monitor their condition
What do my results indicate?
A high level of ASO antibodies in your blood may indicate that you have had a recent or current streptococcal infection. However, it's important to remember that a positive ASO test does not necessarily mean that you have a streptococcal infection. Other symptoms and tests may be necessary to confirm the diagnosis.
When should I order an Anti-Streptolysin O Antibody (ASO) Blood Test?
Individuals may order this test if they have experienced symptoms related to a streptococcal infection. Common signs or symptoms of a streptococcal infection include:
- Sore throat
- Difficulty swallowing
- Red and swollen tonsils
- White patches or pus on the tonsils
- Swollen lymph nodes in the neck
- Fever
- Headache
- Nausea or vomiting
- Body aches
- Rash
It's important to note that not everyone with a streptococcal infection will experience all of these symptoms, and some people may have no symptoms at all. If you suspect you may have a streptococcal infection, it's best to see a doctor for proper diagnosis and treatment.
