Colony count

OK, so if it's first going to a local lab for AFB culturing, then it makes sense that you don't get the colony count. If you send the sputum sample directly to NJH, they go through a long painstaking process of hand counting the colonies on a grid. There are very few labs that do this. Local labs will just test to see if it's AFB positive.

In my heal the system, cultures go first to the MNDept of Health for the AFB test (we are a high TB area, so that must be ruled out.) Then to NJH to be grown out and sensitivity tested. The doc needs to request all 3 (AFB, sensitivity & count) in the order, otherwise only the AFB is done.
