When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Observation
  • Method: Microscopy.light

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

  • Sodium urate crystals [Presence] in Urine sediment by Light microscopy
  • Sodium urate crystals
  • Sodium urate crystals may appear in acidic urines as small, brown needle-like crystals. The crystals are soluble in 10% acetic acid and are sometimes found in patients with cystitis. Sodium urate crystals are the sodium salt of uric acid crystals.
