2nd order laboratory parameters – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Small blood count
- Differential blood count
- Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
- Thyroid parameters (TSH, fT3, fT4) – myxedema may be the cause of carpel tunnel syndrome (KTS).

- CSF puncture (collection of cerebrospinal fluid by puncture of the spinal canal) for CSF diagnosis – in suspected multiple sclerosis (MS).
