I don't work in histology, so I can't tell you the exact process that happens there.

In this particular case, no misdiagnosis happened. It simply increased the average turn around time. When we decontaminate samples, the timer for incubation needs to restart. Non-AFBs can grow pretty fast, they can be detected within 1-2 days.

We still reported results within the acceptable time frame as outlined.

Your comment serves other motive. I can only answer what I know.
