Rich,
That is definitely true also. I guess I just assumed that the question was in regards to 30 separate and individual patients. My bad if that was not the case. Thanks for the clarification.

Negative Control Sheila, Cap requires a negative with each block of patient tissue being stained for immunos, However they also state that if more than one block from the same patient is being tested that only one of the blocks is required for the run.

Negative Control CAP guidelines clearly state that you must run a negative control for each patient tissue. However, if you are running a large amount of a particular antibody, you may validate your procedure to run only one positive control. However, it is just as easy to run a positive control for each patient if you put the control on the same slide as the patient tissue. I don't see any way around the negatives though. We run a negative control on each and every block.

Negative Control Hi Histonetters, We would like to start to run up to 30 H.Pylori on our Benchmark daily. Do GI labs that run H.P. on ALL stomach biopsies run a negative control for each patient tissue for H.P.? I am just curious, as we have a 24 hour TAT, but the Benchmark only holds 30 slides. What's everyone doing?
