The possible reason behind this is always that many experiments were being undertaken making use of traditional LAL tests that aren't particular only to endotoxins. Furthermore, the test effects rely on the sensitivity and interference susceptibility of LAL and how the pre-therapies of blood samples had been executed. Moreover, the timing of specimen collection for blood cultures and the time right up until start off LAL testing in addition to bacterial species can have an effect on the outcome of the tests.

The adoption from the rFC test was slow, which started to vary in 2012 in the event the US FDA and the eu health ministry acknowledged it being an acknowledged substitute.
