Dear seven7:  The normal for any test will vary according to the laboratory performing the test.  One source I have lists the normal as <37 and states that "this value is arbitrary an statistically derived."  Another source lists the normal as 0-33.  The value of this test in breast cancer is not confirmed.

Sorry,  I forgot that this is the breast cancer forum.  My question was about a test for the pancreas.
