Protein S 100 (csf) (Cerebrospinal fluid (csf))
| Specimens: | 1 ml frozen Cerebrospinal fluid (csf) |
| Preanalytics/Notes: | Freeze csf, dispatch deep-frozen in a separate sample. Patients receiving high doses of biotin (> 5 mg / day) should be sampled at least 8 hours after the last application, as high levels of biotin may interfere with the test system. Please send a separate frozen CSF sample for this test. |
| Method: | CLIA |
| Dimension: | µg/l |
| Set-up: | Mon Tue Wed Thu Fri Sat Sun |
| Duration: | 1 day |
| Indication/Significance: | Differential diagnostics in the case of CUP (cancer of unknown primary) Tumour markers for malignant melanoma to estimate the prognosis, to monitor the efficiency of therapy and for follow-up Neurological indications e.g. as destruction parameters for the assessment of organic brain damages such as hypoxia, after resuscitation, cerebral contusion Diagnosis of dementia in the CSF and detection in the case of prion disease (e.g. Creutzfeld-Jakob disease) |
| Interpretation: |
Elevated concentrations more… Elevated concentrations of protein S 100 in the serum can be an indication of a generalised organic brain damages, e.g. in the case of hypoxia, after resuscitation, in the case of cerebral contusion, in the case of cerebrocranial traumas. Elevated protein S 100 levels in the CSF can occur with all acute cerebral lesions. An early determination of protein S 100 after acute cerebral lesions is recommended to estimate the prognosis and, in the event of negative computer tomographic findings, to assess the cerebral involvement. Close-meshed serial analyses may be useful as an additional criterion for the assessment of the progress. Within the scope of a diagnostic assessment of dementia, significantly increased concentrations are indicative of dementia. |
