Ca 19-9 is a cancer marker test specific to the pancreas,liver,gall bladder area. Before hubs last chemo in June his ca 19-9 was 58,Last month at his dr visit it was 110 and this months it's 250. Normal is 0-35. He has another dr appointed 1st of the month and I'm sure his dr will want more chemo sessions. His Ca 19-9 before he had any chemo at all was 4218.
