The possible reason behind this is many research have been carried out applying traditional LAL tests that aren't precise only to endotoxins. On top of that, the test final results depend on the sensitivity and interference susceptibility of LAL And exactly how the pre-treatment options of blood samples were being performed. On top of that, the timing of specimen selection for blood cultures and some time until finally start off LAL testing as well as bacterial species can have an effect on the end result with the tests.
The test involves measurement of the rise in body temperature of rabbits following the intravenous injection of the sterile solution of your compound underneath evaluation.
