2nd order laboratory parameters – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Small blood count
- Differential blood count
- Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
- Urine status (rapid test for: pH, leukocytes, nitrite, protein, glucose, ketone, urobilinogen, bilirubin, blood), sediment, if necessary urine culture (pathogen detection and resistogram, that is, testing suitable antibiotics for sensitivity / resistance).
- Electrolytes – calcium, sodium, potassium ↑, magnesium ↑, phosphate ↑.
- Blood gas analysis (BGA)
- 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.
- Electrophoresis
- Total protein in blood serum
- Coagulation parameters – PTT, Quick
- Serum cortisol (8:00 a.m.), aldosterone – if adrenal insufficiency (adrenocortical weakness) is suspected.
- Toxicological examination – e.g. for drugs, chemicals, plant toxins.
