Amid non-LAL based assays, GC/MS determination aims to focus on lipid A and its three-hydroxy fatty acid molecules. Some experiments suggest that GC/MS Evaluation may very well be clinically efficient if its sensitivity and accuracy were being markedly enhanced [nine,46]. A quantitative approach was designed by fluorescence labeling of 3-hydroxy fatty acid, but a complex procedure with preparative HPLC is required [forty seven]. ELISA is a straightforward and distinct strategy and could be used as being a diagnostic tool if its sensitivity were being noticeably Improved and In the event the program had been able to acknowledge a variety of LPS molecules [48].
