I recently took a pre employment drug test. I received results that I failed with 44ng ml. If my cutoff was 50ng ml for the initial test, why was it sent for confermation testing? Shouldn't my test been reported as negative with a result of 44ng ml with a cutoff 50ng ml?

Initial test cutoff-50ng ml
Confermation test cutoff-15ng ml

My results:
Initial test-44ng ml
Confermation test-44ng ml
