Clinical Pathology Diagnostic Calculators

Evidence-based medical formulas used by pathologists and clinicians to evaluate renal, metabolic, hematologic, and lipid profiles.

Estimated GFR (CKD-EPI & MDRD)

Calculates estimated Glomerular Filtration Rate using standardized serum creatinine, age, and gender parameters to stage chronic kidney disease.


                Formula: 141 × min(Scr/κ, 1)^α × max(Scr/κ, 1)^-1.209 × 0.993^Age

Calculate eGFR →

Friedewald LDL Cholesterol

Estimates low-density lipoprotein cholesterol from standard lipid panel measurements (Total Cholesterol, HDL-C, and Triglycerides).


                Formula: LDL = Total Cholesterol - HDL - (Triglycerides / 5)

Calculate LDL →

Serum Anion Gap

Evaluates acid-base disorders and differentiates high anion gap metabolic acidosis from normal anion gap conditions using electrolyte values.


                Formula: Anion Gap = [Na⁺] - ([Cl⁻] + [HCO₃⁻])

Calculate Anion Gap →

Absolute Neutrophil Count (ANC)

Quantifies the absolute number of circulating neutrophils from total WBC and differential count to assess infection risk and neutropenia severity.


                Formula: ANC = WBC (cells/µL) × (% Segs + % Bands) / 100

Calculate ANC →

Creatinine Clearance (Cockcroft-Gault)

Estimates renal clearance capacity for therapeutic drug dosing and pharmacokinetic adjustments based on age, body weight, and serum creatinine.


                Formula: CrCl = [(140 - Age) × Weight (kg)] / [72 × S.Cr (mg/dL)]

Calculate CrCl →

Corrected Calcium for Albumin

Adjusts total serum calcium concentration in hypoalbuminemic states to reflect true physiological ionized calcium status.


                Formula: Corrected Ca = Total Ca + 0.8 × (4.0 - Serum Albumin)

Calculate Corrected Calcium →

Standardized Laboratory Diagnostics Modules

Complete Blood Count (CBC)

Hemoglobin, RBC, WBC differential, Platelets, Hematocrit, and RBC Indices with automated age/gender ranges.

Liver Function Test (LFT)

Total & Direct Bilirubin, SGOT/AST, SGPT/ALT, Alkaline Phosphatase, Total Protein, Albumin, and A:G Ratio.

Kidney Function Test (KFT)

Blood Urea Nitrogen, Serum Creatinine, Uric Acid, Calcium, and calculated Electrolyte parameters.

Lipid Profile & Cardiac Risk

Total Cholesterol, HDL, LDL, VLDL, Triglycerides, Total/HDL Ratio, and Non-HDL cholesterol assessment.

Frequently Asked Questions & Laboratory Standards

What are biological reference intervals in pathology?

Biological reference intervals represent the central 95% distribution of values observed in a healthy reference population. Clinical laboratory results outside these bounds are highlighted to assist clinicians in diagnosing and monitoring medical conditions.

How does PathoWiz ensure data security and privacy?

PathoWiz employs local-first client encryption and Firestore security rules, ensuring patient medical data is accessible solely by authenticated laboratory staff. No private patient data is shared with third-party advertising partners.

Can clinical calculators replace physician interpretation?

No. Clinical calculations provide standardized mathematical estimations to support diagnostic workflows. All parameters must be interpreted within the full clinical context by a licensed physician or registered pathologist.
