In the toddler with URI, which test result was negative?

Explanation:
Most upper respiratory infections in toddlers are viral, so tests that look for a bacterial cause, like a throat culture for group A Streptococcus, are expected to be negative. A negative throat culture supports a non-bacterial, viral URI rather than strep throat, which is important because it helps avoid unnecessary antibiotic treatment. The other tests serve different purposes: chest X-ray is used if pneumonia is suspected, the CBC is a broad inflammatory marker that can vary, and urinalysis screens for urinary tract infection. In the typical URI scenario, the throat culture being negative aligns with a viral etiology.
