Between non-LAL dependent assays, GC/MS dedication aims to target lipid A and its 3-hydroxy fatty acid molecules. Some research propose that GC/MS Evaluation might be clinically helpful if its sensitivity and accuracy had been markedly improved [nine,forty six]. A quantitative method was made by fluorescence labeling of three-hydroxy fatty acid, but a fancy course of action with preparative HPLC is necessary [forty seven]. ELISA is an easy and unique method and will be made use of like a diagnostic Software if its sensitivity were being drastically Improved and If your system were being able to acknowledge many LPS molecules [48].
