1st order laboratory parameters – obligatory laboratory tests.

- Antibody detection of vers. Serotypes
Direct or indirect detection of Yersinia enterocolitica (intestinal pathogen) must be reported if the evidence indicates acute infection (Law on Prevention and Control of Infectious Diseases in Humans).
2nd order laboratory parameters – depending on the results of the history, physical examination, and obligatory laboratory parameters – for differential diagnostic clarification.
- Small blood count
- Inflammatory parameters – CRP (C-reactive protein) or PCT (procalcitonin).
- 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
