Our antibody-ID section in our procedure manual has gotten a bit bloated, but only because it is reasonably comprehensive. While we, like many, use the "3x3" rule, it becomes more involved when you start looking at individual antigens and antibody characteristics. (For example, a patient that is only producing anti-E is likely to start producing anti-c after they are transfused a few times. For this reason, most labs will screen units for anti-c for c-antigen negative patients producing anti-E.)
Also, there are other considerations for certain situations, (such as a patient with a previously identified antibody need not have 3 positive cells to rule it in).
In general, we have a procedure that details the 3x3 step by step. Then there are individual charts, tips, and notes for common specifics regarding certain situations, such as how to get around cold agglutinins, or the use of enzymes.
You should be able to figure out what to put in your procedure from looking at the AABB manual. If your current procedure for antibody ID seems totally inadequate, you may want to start from scratch.
Hope this helps. Antibody ID is the most robust procedure we have in our BB manual.
