🧪 Lab Test Interpreter (report read-out)
Enter the values from a lab report and the tool flags each as high, low or critical, auto-calculates eGFR, anion gap, albumin-corrected calcium, Friedewald LDL and FIB-4, and recognises liver-injury type, anemia class and thyroid pattern. Covers CBC, liver & renal function, electrolytes, glucose, lipids, inflammation, thyroid and coagulation — computed locally, never uploaded.
Beyond per-test flags, it chains derived indices automatically so nothing is missed (e.g. albumin-corrected calcium when albumin is low, or the limits of Friedewald LDL when TG is high).

This is an interactive, structure-by-structure assessment. Open the dedicated tool to enter the age, choose the sequence and mark each finding.
Open interactive assessment →When to use
For rapid read-out in clinic/ED, checking abnormal results on rounds, and interpreting health-screen reports at follow-up. Entering sex and age enables eGFR and sex-specific reference ranges; enter only what you have. Critical values are highlighted separately.
How it works
Each value is graded into five bands (critical-low / low / normal / high / critical-high) against common adult reference ranges. Derived indices: eGFR = CKD-EPI 2021 (race-free); anion gap = Na − Cl − HCO₃; corrected Ca = measured Ca + 0.02×(40 − albumin g/L); LDL (Friedewald) = TC − HDL − TG/2.2 (TG < 4.5 mmol/L); FIB-4 = age × AST / (PLT × √ALT). Liver pattern is classified as hepatocellular / cholestatic / mixed from the transaminase-vs-ALP profile.
Key points
- Beyond per-test flags, it chains derived indices automatically so nothing is missed (e.g. albumin-corrected calcium when albumin is low, or the limits of Friedewald LDL when TG is high).
- eGFR uses the 2021 race-free CKD-EPI equation and reports the CKD stage (G1–G5).
- Liver injury is split into hepatocellular / cholestatic / mixed; anemia is classified by MCV into micro-/normo-/macrocytic; thyroid is read from TSH + FT4 into primary/subclinical hypo- or hyperthyroidism.
- Critical values are highlighted for immediate handling per local protocol.
- Reference ranges vary by lab and assay — the tool's values are common defaults; always defer to your own laboratory's reference intervals.
