Some studies suggest that GC/MS Assessment could be clinically helpful if its sensitivity and precision have been markedly enhanced [nine,46]. A quantitative method was made by fluorescence labeling of three-hydroxy fatty acid, but a complex procedure with preparative HPLC is necessary [47]. ELISA is an easy and precise system and could be utilized to be a diagnostic Device if its sensitivity were noticeably Improved and In the event the method were being capable to acknowledge different LPS molecules [forty eight].
