What Changes the Differential

Age modifiers

  • •Age changes baseline risk: pediatric, adult, and older patients have different top causes.

Severity and acuity

  • •Escalating severity, hemodynamic instability, or neurologic compromise should always override watchful waiting.

Timing and pattern

  • •Timing matters: onset speed, duration, and recurrence pattern help separate benign from high-risk causes.

Associated symptoms

  • •Associated symptom clusters (e.g., Watery eyes + Eye Redness, Watery eyes + Eye Pain, Watery eyes + Headache) materially alter the differential.

When Testing Is Needed

Immediate testing when red flags are present

  • •Focused examination with baseline labs if symptoms persist
  • •Escalate to urgent workup when red flags appear

Group-directed workup

  • •CBC with differential
  • •CRP / ESR
  • •Targeted cultures or PCR
  • •Lactate if sepsis concern
  • •Focused neurologic exam
  • •CT/MRI when red flags are present
  • •Lumbar puncture when indicated
  • •Glucose and electrolytes
