Clinical takeaway

Dipstick blood with no RBCs suggests myoglobin/haemoglobin.

When to use

Read urinalysis by component to localise a renal vs urological process; microscopy on a fresh sample is the gold standard.

How it works

RBC casts/dysmorphic RBCs + proteinuria = glomerular; muddy-brown granular casts = ATN; nephrotic-range proteinuria > 3.5 g/24h.

Key points

  • Dipstick blood with no RBCs suggests myoglobin/haemoglobin.
  • The dipstick is insensitive to light chains (Bence Jones).
  • WBC casts suggest pyelonephritis or acute interstitial nephritis.
  • Quantify protein with UPCR; separate prerenal with FENa; assess RTA with the urine anion gap.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

ViewCasts

→InterpretationCasts

  • Hyaline casts：Concentrated urine/normal/diuresis — non-specific
  • RBC casts：Glomerulonephritis, vasculitis (a marker of nephritic syndrome)
  • WBC casts：Pyelonephritis, acute interstitial nephritis
ViewDipstick/appearance

→InterpretationDipstick / appearance

  • Blood positive but no RBC on microscopy：Myoglobinuria (rhabdomyolysis) or haemoglobinuria (haemolysis)
  • Leukocyte esterase + nitrite：Suggests UTI (nitrite is specific, positive with Enterobacteriaceae)
  • Glucose/ketones：Glycosuria/ketosis; specific gravity and pH help judge concentration and acid-base

FAQ

Frequently asked questions

What are the limits and cautions when using Urinalysis Interpretation?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does Urinalysis Interpretation upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Urinalysis Interpretation calculated in practice? Can you show a worked example?
