Testing is ordered to help diagnose sepsis, distinguish it from other conditions, and to evaluate and monitor the function of the affected person's organs, blood oxygenation, and acid-base balance.
Testing may include:
- Blood culture – to detect microorganisms and evaluate their susceptibility to antimicrobial drugs
- Urine culture and cultures of other body fluids as indicated – to detect the source and type of infection
- CBC (Complete blood count) – to evaluate red and white blood cells and platelets
- Lactate – increased levels can indicate organ dysfunction
- Blood gases – to evaluate oxygen in the blood and acid-base balance
- Procalcitonin – sometimes used to distinguish sepsis and other conditions that cause similar symptoms
- Comprehensive metabolic panel (CMP) – to monitor organ status, electrolyte balance, and blood glucose
- PT and/or PTT or other clotting tests to evaluate clotting status
- C-reactive protein (CRP) – to detect inflammation in the body
May be ordered to evaluate organ status, detect complications, and to detect location of infection:
- ECG – to evaluate heart rhythm or injury
- CT (Computed Tomography) scan
- MRI (Magnetic Resonance Imaging)
