Passage / Scenario
A nurse is reviewing the laboratory results of a child who was recently admitted for suspected rheumatic fever.Which of the following laboratory tests can contribute to confirming this diagnosis? Select all that apply.
Correct answer
A,D,E
Rationale
The correct laboratory tests to confirm the diagnosis are ASO titer, ESR, and CRP. ASO titer is used to detect antibodies against streptolysin O produced by Streptococcus bacteria, which helps diagnose streptococcal infections. ESR measures inflammation levels in the body, which can be elevated in various conditions including infections. CRP is a marker of inflammation and infection, so an elevated level can support the diagnosis. PTT is primarily used to evaluate blood clotting disorders, not specific for confirming this diagnosis. BUN is a measure of kidney function and not directly related to this diagnosis.
