2nd order laboratory parameters – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Small blood count [MCV ↑ → possible indication of alcohol dependence, vitamin B12 and folic acid deficiency]
- Differential blood count
- Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
- Fasting glucose (fasting blood glucose), if necessary oral glucose tolerance test (oGTT) [hypoglycemia/ hypoglycemia?]
- Electrolytes – calcium, sodium [hyponatremia (sodium deficiency)?]
- Liver parameters – aspartate aminotransferase (AST, GOT), alanine aminotransferase (ALT, GPT), gamma-glutamyl transferase (γ-GT, gamma-GT; GGT), alkaline phosphatase, bilirubin [γ-GT ↑, possible indication of alcohol dependence].
- VDRL test – for suspected neurolues.
- CSF puncture (collection of cerebrospinal fluid by puncture of the spinal canal) for CSF diagnosis – if encephalitis (inflammation of the brain) is suspected.
