What Changes the Differential

Age modifiers

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

Severity and acuity

  • •Severe or sudden-onset presentation immediately increases urgency and narrows toward dangerous causes.
  • •Red-flag triage first: rule out urgent causes such as Aortic Dissection and Pancreatitis.

Timing and pattern

  • •Pattern "at Night" changes pre-test probability and guides targeted testing.
  • •Pattern "— Sudden Onset" changes pre-test probability and guides targeted testing.
  • •Pattern "after Exercise" changes pre-test probability and guides targeted testing.
  • •Pattern "in Elderly Patients" changes pre-test probability and guides targeted testing.

Associated symptoms

  • •Associated symptom clusters (e.g., Back pain + Fatigue, Back pain + Abdominal Pain, Back pain + Nausea) materially alter the differential.

When Testing Is Needed

Immediate testing when red flags are present

  • •Vital signs and focused triage examination
  • •Pulse oximetry and ECG
  • •Basic blood panel (CBC, CRP, electrolytes, glucose)
  • •Immediate imaging based on dominant red flags

Group-directed workup

  • •CBC / CRP
  • •Liver panel and lipase
  • •Stool tests
  • •Abdominal ultrasound
  • •CBC with differential
  • •CRP / ESR
  • •Targeted cultures or PCR
  • •Lactate if sepsis concern
