Measles vs. Rubella: Laboratory Diagnosis with Serology and PCR

Why Testing Is Needed

Clinical presentation overlaps; lab confirmation is essential.

Standard Tests

  • Serology (IgM/IgG): ELISA or CLIA on serum.
  • Specimens: Acute serum (within 7 days of rash) + convalescent serum (≥10–14 days later); also throat/nasopharyngeal swabs, urine for PCR.

Interpretation

  • IgM positive = recent infection.
  • IgG rise (4‑fold) between acute/convalescent = confirmed.
  • PCR detects viral RNA for rapid diagnosis.
