It is recommended to run a negative AFB control to rule out false positives. Some sources of water have acid fast organisms, not TB, and if the water is used in the water baths or for staining you could pick up those organisms. The recommendation is to cut a section of tissue, known NOT to contain AFB organisms, and run it through with the positive control and patient. You would pick it up on the same water bath that you used for the patient.

If so is there a regulation that states negative controls should be run for AFB stains. I seem to recall seeing such a regulation but cannot find it. Thanks for your help!
