1st order laboratory parameters – obligatory laboratory tests.
- Small blood count
- Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
- Liver parameters – alanine aminotransferase (ALT, GPT), aspartate aminotransferase (AST, GOT), glutamate dehydrogenase (GLDH) and gamma-glutamyl transferase (gamma-GT, GGT).
Laboratory parameters 2nd order – depending on the results of the history, physical examination and the obligatory laboratory parameters – for differential diagnostic clarification.
- Differential blood count
- Iron metabolism parameters – ferritin, reticulocyte hemoglobin, transferrin receptor.
- Renal parameters – urea, creatinine, cystatin C or creatinine clearance, if necessary.
- Rheumatoid factor, antinuclear antibodies (ANA), HLA-B27 – if rheumatic diseases are suspected.
- Measurement of enzyme activity with a dry blood test (e.g., of the enzyme β-glucocerebrosidase in Gaucher’s disease) – for example, detection of Gaucher’s disease or other rare metabolic diseases.
