Practice Question
A nurse is caring for a child who was admitted with suspected rheumatic fever. The provider prescribes an anti-streptolysin O (ASO) titer. The parent asks the nurse the purpose of the test. Which of the following responses should the nurse make?
Answer Choices:
Correct Answer:
"This test will confirm if your child had a recent streptococcal infection."
Rationale:
🧬 The anti-streptolysin O (ASO) titer detects antibodies produced in response to streptolysin O, an enzyme released by group A beta-hemolytic streptococcus.
🧬 A high ASO titer suggests a recent streptococcal infection, which supports the diagnosis of rheumatic fever, a post-infectious inflammatory disease.
🧬 It is not used to measure antibiotic levels or immunity. Instead, it helps confirm if the triggering infection occurred, which is crucial for diagnosing RF.
🧬 This test is particularly valuable when a prior throat infection was untreated or undocumented.
