Test Description & Overview

Serum Uric Acid: The heterocyclic end-product of purine nucleoside catabolism in humans, formed via xanthine oxidase activity and excreted primarily by the kidneys (70%) and intestinal tract (30%).

Standard Reference Range

Adult Males: 3.5 - 7.2 mg/dL (208 - 428 umol/L); Adult Females: 2.6 - 6.0 mg/dL (155 - 357 umol/L); Target for Gout Management: <6.0 mg/dL (<360 umol/L).

Elevated (High) Values

  • Hyperuricemia: Acute Gouty Arthritis or Tophaceous Gout
  • Renal Urate Calculi (Nephrolithiasis) or Urate Nephropathy
  • Tumor Lysis Syndrome (Massive purine breakdown post-chemotherapy)
  • Metabolic Syndrome, Chronic Kidney Disease, or Diuretic Use (Thiazides)

Decreased (Low) Values

  • Fanconi Syndrome or Renal Tubular Urate Wasting
  • Xanthine Oxidase Inhibitor Therapy (Allopurinol / Febuxostat Overdose)
  • Severe Liver Disease or Hereditary Xanthinuria

Clinical Alignment & Significance

Hyperuricemia (>6.8 mg/dL exceeds physiological monosodium urate solubility limit), predisposing to articular urate crystal deposition; in patients with gout, ACR 2020 guidelines mandate treat-to-target urate lowering to <6.0 mg/dL.

Diagnostic Guidance Notice

Standard laboratory reference ranges vary based on the testing facility. Significant deviations require immediate clinician review to rule out severe medical pathology.
