2nd order laboratory parameters – depending on the results of history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Small blood count
- Inflammatory parameters – CRP (C-reactive protein).
- Fasting glucose (fasting blood sugar)
- If necessary, serology for borrelia, toxoplasmosis, treponemas, bartonella – if unclear papilledema (swelling of the optic disc due to increased intracranial pressure (intracranial pressure)).
- If necessary, conjunctival swab
- If necessary, cerebrospinal fluid puncture (collection of cerebrospinal fluid by puncture of the spinal canal) for CSF diagnosis; but before that, if papilledema is unclear, conduct a cranial MRI.
