Laboratory parameters of the 1st order – obligatory laboratory tests.
- Small blood count
- Differential blood count
Laboratory parameters 2nd order – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Iron metabolism parameters such as ferritin, reticulocyte hemoglobin, transferrin receptor.
- Inflammatory parameters – CRP (C-reactive protein).
- Liver parameters – alanine aminotransferase (ALT, GPT), aspartate aminotransferase (AST, GOT), alkaline phosphatase, bilirubin.
- Renal parameters – urea, creatinine.
- Rheumatism diagnostics – CRP (C-reactive protein) or ESR (blood sedimentation rate); rheumatoid factor (RF), CCP-AK (cyclic citrulline peptide antibodies), ANA (antinuclear antibodies).
- Serological examinations – for suspected infectious diseases.
- 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) – if bone metastases are suspected.
- Blood culture – if sepsis is suspected.
