On top of that, the test final results depend upon the sensitivity and interference susceptibility of LAL And the way the pre-solutions of blood samples were executed. In addition, the timing of specimen collection for blood cultures and some time until finally start off LAL testing and also bacterial species can impact the end result from the tests.
