Bedside

Clinical calculators & test profiles

Illustrative bedside arithmetic. These calculators are educational and do not feed the matching engine — to record results for a patient, use the laboratory trajectory.

Showing conventional units. Creatinine, calcium and glucose inputs below use mg/dL — convert before entering if your laboratory reports differently.

Creatinine clearance (Cockcroft–Gault)

Not validated in unstable renal function, extremes of weight or pregnancy.

Estimated CrCl: — mL/min

qSOFA

A screening prompt for organ dysfunction — not a diagnosis of sepsis.

qSOFA: 0/3

Mean arterial pressure

MAP: — mmHg

Anion gap

Uncorrected for albumin; example adult range 8–12 mmol/L.

Anion gap: — mmol/L

Corrected calcium & sodium

Albumin correction and glucose correction are estimates only.

Corrected calcium: — mg/dL · Corrected sodium: — mmol/L

BMI & body surface area

BSA by the Mosteller formula.

BMI: — kg/m² · BSA: — m²

Reference values are example adult ranges only; they vary by laboratory, method and population and must never be used as universal cutoffs.
