Laboratory parameters of 1st order – obligatory laboratory tests.
- Small blood count
- Inflammatory parameters – CRP (C-reactive protein) or PCT (procalcitonin).
- Blood gas analysis (ABG) [To assess transpulmonary oxygen transport, Horowitz oxygenation index (PaO2/FiO2; PaO2 = arterial oxygen partial pressure in mmHg,FiO2 = inspiratory oxygen concentration) is determined: < 200 mmHg (in ARDS)]
- Liver parameters – alanine aminotransferase(ALT, GPT), aspartate aminotransferase (AST, GOT), glutamate dehydrogenase (GLDH) and gamma-glutamyl transferase (gamma-GT, GGT), alkaline phosphatase, bilirubin.
- Renal parameters – urea, creatinine, cystatin C or creatinine clearance, if necessary.
- Coagulation parameters – PTT, Quick
- Blood cultures, smears from drains, etc.
