2nd order laboratory parameters – depending on the results of the medical history, physical examination, etc. – for differential diagnostic clarification
- Small blood count
- Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
- Electrolytes – calcium, chloride, potassium, magnesium, sodium, phosphate.
- 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.
- Highly sensitive cardiac troponin T (hs-cTnT) or troponin I (hs-cTnI); creatine kinase (CK, CK-MB), lactate dehydrogenase (LDH) – if myocardial infarction (heart attack) is suspected.
- Alkaline phosphatase (AP) isoenzymes, ostase, urinary calcium (tumor hypercalcemia (synonym: tumor-induced hypercalcemia (calcium excess), TIH) is one of the most common symptoms in paraneoplastic syndromes), PTHrP (parathyroid hormone-related protein; the constellation with decreased parathyroid hormone (PTH) and increased PTHrP is typical for tumor hypercalcemia) – when bone metastases are suspected.
