Some research counsel that GC/MS Investigation may be clinically successful if its sensitivity and accuracy ended up markedly enhanced [nine,46]. A quantitative technique was designed by fluorescence labeling of three-hydroxy fatty acid, but a posh process with preparative HPLC is required [forty seven]. ELISA is an easy and precise system and could be used as being a diagnostic Device if its sensitivity ended up considerably Increased and When the process ended up capable to recognize numerous LPS molecules [48].
