Laboratory parameters of the 1st order – obligatory laboratory tests.
- Small blood count
- Inflammatory parameters – CRP (C-reactive protein).
- Urine status (rapid test for: pH, leukocytes, nitrite, protein, glucose, ketone, urobilinogen, bilirubin, blood), sediment, urine culture if necessary (pathogen detection and resistogram).
Laboratory parameters 2nd order – depending on the results of the history, physical examination and the obligatory laboratory parameters – for differential diagnostic clarification.
- Electrolytes – potassium, magnesium, sodium – if ileus is suspected.
- Fasting glucose, oral glucose tolerance test (oGTT) if necessary.
- Pancreatic parameters – amylase, elastase (in serum and stool), lipase.
- 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.
- Test for occult (not visible) blood in the stool.
- Pregnancy test (quantitative HCG)
