Which specimen type is noted as the specimen of choice for suspected epiglottitis in this context?

• A. Blood
• B. Throat swab
• C. Sputum
• D. Urine

Answer: (A)

When epiglottitis is suspected, identifying the infecting organism quickly and safely is essential, and bacteremia is common with this condition. Blood cultures are the most informative and practical way to detect the causative agent, especially Haemophilus influenzae, without risking airway manipulation or poor sample quality. Throat swabs can be unreliable because inflamed tissues and normal oropharyngeal flora may confound results, and obtaining them can be risky in a patient with airway compromise. Sputum is often not obtainable in children and may not reflect the epiglottic infection, while urine typically won’t reveal the etiologic agent. Thus, blood is the best specimen for diagnosing suspected epiglottitis.
