# Ephedrine/Pseudoephedrine Differentiation, Serum or Plasma

> This test measures and identifies the specific amounts of ephedrine and pseudoephedrine in your blood. These are stimulant drugs often found in cold medicines, diet pills, or herbal supplements. The results help explain symptoms like a racing heart or high blood pressure by confirming exactly which substance is in your system. This differentiation helps rule out confusion between a standard decongestant and other types of stimulants. It does not, however, determine the intent behind the use or diagnose a substance use disorder.
