Fibrin(ogen degradation product concentration (SFP) as a diagnostic parameter for the differentiation of artifical and essential blood in cerebrospinal fluid

The fibrin(ogen) degradation product concentration is another differential-diagnosis parameter for distinguishing between artificially blood-stained and essentially blood-stained CSF. Determination of the fibrin(ogen) degradation product concentration has been found to be a reliable method of recognizing natively and artificially blood-stained CSF as being different.
