Physician wants to do another in three months. sherwoodughes Wed, 24 Oct 2007 00:00:00 GMT my dad did have the fish test and did have cancer.  we were told that depending on which gene was affected it carried a more signifant result.  i believe that abbott labs makes the test so i suggest calling them to see the false positive rate.  if i remember correctly it wasnt very high but im not sure so you need to find out.  our doc in chicago dr gary steinberg knew a lot about this test and sits on the board so perhpas you can consult with him.  good luck and keep being agressive in your research!
