        # for each ORC, look up a lab request, create if necessary
        # and update it.
        for lr in self.ORC:
            try:
                req = cr.get_lab_request(req_id=lr.filler_order_number,
                                         lab=test_org_pk)
            except ValueError:
                req = None
            if not req:
                req = cr.add_lab_request(lab=test_org_pk,
                                         req_id=lr.filler_order_number,
                                         encounter_id=enc_pk,
                                         episode_id=ep_pk)

 note that that's ORC 003 - filler_order_number.

 ORC 004 - placer group number - is in fact entirely ignored.
*double-checks*.... yep, it's not even stored anywhere, let alone
checked.  likewise ORC 002 - placer order number - is also ignored.

 if however you're telling me that ORC003 can be None then we're
slightly stuffed (that's an understatement, btw), as the whole thing
grinds to a halt because you'll be unlikely to ever successfully
identify a lab request.
