The SAH diagnosis of choice is a computed tomography (CT) scan of the brain. The scan is accurate up to 12 hours after an SAH event in 98% of cases. During the first week following the SAH event, the diagnostic accuracy drops to 50%. To avoid false negatives and improve diagnostic accuracy, a control measurement is necessary. One possibility for improving diagnostic accuracy is by using spectrophotometric analysis of cerebrospinal fluid (CSF) as described in the “Revised national guidelines for analysis of cerebrospinal fluid for bilirubin in suspected subarachnoid haemorrhage” a research article, first published in 2008 by Dr. Anne Cruickshank.
UV Vis Workflow Increases Diagnostic Reliability
LabX® laboratory software from METTLER TOLEDO supports the automatic UV Vis solution for SAH control measurement. LabX automatically detects the presence of hemoglobin and bilirubin and calculates the absorbance. The method also runs the implemented decision tree and gives the user a prompt result. The process can be easily started via the instrument or a PC. The measurement, results and outcome are stored in a database and can be retrieved at any time.
