Test Code Urinalysis, microscopic if indicated, reflex to culture when indicated/UAC Urinalysis, microscopic if indicated, reflex to culture when 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/UAM.
  • If physician wants a culture if indicated order UAC "Urinalysis, microscopic if indicated, reflex to culture when indicated".
  • If specimen is grossly bloody or viscous test will be canceled and UA "Urinalysis (UA), Routine will be ordered.

Methodology

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

IQ200 Elite Microscopy System

 

Note: 1. If dipstick is positive for blood, leukocyte esterase, nitrates, or protein a microscopic examination of the urine will be performed.

2. If dipstick is positive for leukocyte esterase, nitrates, or >5 WBC a  "Culture, Urine" will be performed at an additional charge.

3.If patient is ≤ 2 years old order "Urinalysis, microscopic if indicated/UA/I" or "Urinalysis, with madatory microscopic/UAM/I", order urine culture separately.
