This is what the ABP says in their booklet for AP only:
"36 months of full-time training in an accredited APCP or AP program. Training must include at least 24 months of structured AP training. The remaining 12 months are flexible; and may include AP and/or CP. Training may include up to 6 months of research done during the pathology training program with the approval of the program director.
The truth is that the ABP doesnt define what "Structured AP training" is. Anything that your program decides to construe as AP training and is "structured" technically counts.
Well, I think you are required to do some molecular path (including cytogenetics) and some hemepath (they test both on the AP boards). I believe informatics can also count.
I'm not so sure about that. I had a bone marrow core biopsy as one of my virtual slides on the AP exam. And it was a hemepath diagnosis. Flow I am not so sure about, but on the RISE it is in "special topics" which AP people take.
That would seem like a strange way of doing things, since all three are intricately related. I don't know of any hemepath rotation that doesn't involve counting marrows or going over flow cytometry, and I couldn't see making the diagnosis without all of that information so that doesn't sound right to me. I know my institution doesn't make the AP-only residents do wet heme like coags or hemoglobins, but they certainly do marrows, lymph nodes, and flow.
