2nd-order laboratory parameters-depending on the results of the history and physical examination-for differential diagnostic clarification.
- Small blood count
- Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
- Fasting glucose (fasting blood glucose).
- Blood gas analysis (BGA)
- High-sensitivity cardiac troponin T (hs-cTnT) or troponin I (hs-cTnI) – for suspected myocardial infarction (heart attack).
- NT-proBNP (N-terminal pro brain natriuretic peptide) – for suspected heart failure (cardiac insufficiency).
- Rheumatism diagnostics – CRP (C-reactive protein) or BSG (blood sedimentation rate); rheumatoid factor (RF), CCP-AK (cyclic citrulline peptide antibodies), ANA (antinuclear antibodies).
- Coagulation parameters – Quick, PTT
