2nd order laboratory parameters – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.

  • Small blood count
  • Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
  • Electrolytes – potassium, magnesium
  • Thyroid parameters – TSH
  • Highly sensitive cardiac troponin T (hs-cTnT) or troponin I (hs-cTnI) – to exclude myocardial infarction (heart attack).
