Test Code Urinalysis, microscopic if indicated / UA/I Urinalysis, microscopic if indicated

Important Note

  • If a physician wants microscopic examination irregardless of dipstick results order: Urinalysis, with mandatory microscopic/UAM/I or Urinalysis, with mandatory microscopic, relex to culture if indicated/UAMC
  • If physician wants a culture if indicated order: Urinalysis, microscopic if indicated, reflex to culture when indicated/UAC.
  • If specimen is grossly bloody or viscous test will be canceled and Urinalysis (UA), Routine/UA will be ordered.

Methodology

iChem Velocity Strips. Includes specimen type, color, clarity, bilirubin, blood, glucose, leukocyte esterase, nitrates, pH, protein, urobilinogen.
