Even with their sensitivity and specificity for endotoxins of Gram destructive bacteria, the LAL test is proscribed – as it can not detect exotoxins of Gram beneficial microbes and cellular elements of viruses and fungi.
Sample template on how to generate your study achievements and outcomes when applying for any fellowship or grant
Lastly, we introduce the diagnostic performance with the serum β-glucan assay and its contribution into the early diagnosis of sufferers at risk for invasive fungal diseases and fungal septicemia.
