BACTERIAL INFECTION FUNDAMENTALS

Clinical clarity, from first signs to source control.

Syndromic reasoning stays primary while Bactif connects body systems, pathogens, diagnostics and sepsis escalation.

Clinical calculators & test profiles

Illustrative bedside arithmetic and a reference test profile. These calculators are educational and do not feed the matching engine — to record results for a patient, use the Laboratory trajectory inside an assessment.

Showing conventional units. Creatinine, calcium and glucose inputs below use conventional units (mg/dL); convert before entering if your laboratory reports in SI.

Creatinine clearance (Cockcroft–Gault)

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

Enter values to calculate

qSOFA screening

RR ≥ 22, SBP ≤ 100 mmHg, GCS below 15. A score under 2 does not exclude sepsis.

0/3

Mean arterial pressure

(SBP + 2 × DBP) ÷ 3. Interpret with perfusion, not in isolation.

Enter values to calculate

Anion gap (albumin-corrected)

Na − Cl − HCO₃; add 2.5 per g/dL albumin below 4.

Enter values to calculate

Corrected calcium

Calcium + 0.8 × (4 − albumin g/dL). Ionised calcium is preferred when available.

Enter values to calculate

Glucose-corrected sodium

Na + 0.024 × (glucose mg/dL − 100).

Enter values to calculate

BMI and body-surface area

BSA by the Mosteller formula. Dosing weight decisions need pharmacy input.
