Your question concerning the new CAP question about intrinsic/extrinsic is quite relevant to me as we have been discussing this very question in our laboratory just this week. According to the CAP Supplement to Flow Cytometry version 19970, this question relates to the nonspecific binding of serum immunoglobulin by cells via Fc receptors. As you should know a number of leukemia/lymphoma samples have a high propensity for non-specific binding if run "neat". It would seem that if your laboratory is taking the proper steps to reduce this nonspecific binding (e.g. by blocking techniques or by coating with protein) that your CAP inspector should be satsfied.
