Bethesda System (Thyroid FNA)Standardized cytopathological classification of thyroid nodules to guide surgical management.

Breslow Depth (Melanoma)The primary prognostic vertical thickness measurement for primary cutaneous melanoma staging.

Calculated Serum OsmolalityScreens for the presence of toxic alcohols and other unmeasured osmotically active substances.

Corrected Calcium (Albumin)Estimates physiologically active calcium levels in patients with hypoalbuminaemia.

Corrected Sodium (Hyperglycaemia)Accounts for the dilutional effect of glucose on serum sodium during metabolic emergencies.

Delta-Delta RatioResolves mixed acid-base disorders in the presence of a high anion gap metabolic acidosis.

Fractional Excretion of Sodium (FENa)Differentiates prerenal azotemia from acute tubular necrosis in patients with AKI.

Fractional Excretion of Urea (FEUrea)Validates AKI etiology in patients whose sodium handling is altered by diuretics.

Partin Tables (Prostate Cancer)Predicts pathological stage at radical prostatectomy based on PSA, Gleason score, and clinical T-stage.

Serum Anion GapStandardizes metabolic acidosis triage by accounting for albumin concentration and unmeasured anions.

About

Pathology

The Pathology and Laboratory Medicine hub provides clinician-validated tools for interpreting complex diagnostic data. From serum electrolyte deviations and acid-base modeling (Anion Gap, Delta-Delta) to standardized malignancy reporting (Bethesda, Breslow) and urologic staging nomograms (Partin), our suite transforms raw laboratory results into actionable clinical insights.

Covered Areas

Acid-Base & Electrolyte Modeling
Thyroid Cytopathology (Bethesda)
Dermatopathologic Staging (Breslow)
Urologic Prognostic Nomograms (Partin)

All tools are based on published clinical evidence. Results should be interpreted alongside individual patient presentation and current institutional guidelines.
