Amongst non-LAL dependent assays, GC/MS dedication aims to focus on lipid A and its three-hydroxy fatty acid molecules. Some studies recommend that GC/MS Evaluation may be clinically productive if its sensitivity and accuracy have been markedly enhanced [9,forty six]. A quantitative process was designed by fluorescence labeling of three-hydroxy fatty acid, but a fancy approach with preparative HPLC is required [forty seven]. ELISA is a simple and precise approach and could be applied being a diagnostic Device if its sensitivity were substantially Increased and if the method had been equipped to recognize different LPS molecules [forty eight].
