Ordering the Antistreptolysin O Antibody Test
Ordering the Antistreptolysin O Antibody Test is important for detecting a past infection with group A Streptococcus bacteria. This test measures the level of antistreptolysin O antibodies in your blood, which can indicate if your body has responded to a strep infection. Interestingly, elevated levels of these antibodies can persist for weeks or even months after the infection has resolved.
Here are some specific benefits of ordering this test:
- Helps identify recent strep infections that may not show symptoms.
- Assists in diagnosing conditions like rheumatic fever or glomerulonephritis.
- Provides insight into the effectiveness of treatment for strep-related conditions.
- Supports monitoring of recurrent strep infections.
Who Should Consider the Antistreptolysin O Test
Individuals who have experienced symptoms like joint pain or swelling, which may be linked to a previous strep infection, should consider this test. For example, a person who has had a sore throat followed by unexplained joint pain might find this test helpful in understanding the cause.
Other scenarios where this test may be beneficial include:
- Experiencing skin rashes after a sore throat.
- Having a family history of rheumatic fever.
- Developing kidney issues after a strep infection.
- Children with recurring strep throat infections.
- Adults with unexplained fever and fatigue.
Ordering this test can help identify underlying issues related to past strep infections. Not ordering it might leave you without answers to persistent symptoms.
Preparing for the Test
Fasting is not required for this test. It’s important to follow your doctor’s instructions regarding any medications or supplements you are taking.
