Question 1

is a 9 level normal on a ca 19-9 test?

Accepted Answer

Yes, it seems to be : It is in the normal range. Why did you have it done?

Question 2

if ca19-9 within normal levels or negative, are you cancer free? is there a test to show that you are in the %  group that can't produce the antigen?

Accepted Answer

Misconception: Only a handful of cancers produce ca19-9, and even then it's won't be detectable at a significant level unless there's enough mass of the cancer to produce it. This is not a screening test. If levels drop to undetectable after surgery, it's no guarantee of a cure. It's most useful to follow and watch for recurrences of a known ca19-9 producing cancer.

Question 3

beta 2 microglobulin level- 1.58. creatine kinase-170. ca 19-9 level - 10. are these normal values ? ca 19-9 was 0 a few years ago?

Accepted Answer

: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, your results are within normal limits.    Wish you good health!

Question 4

my ca 19-9 test came back a 9 is that normal? thank u:-)

Accepted Answer

Yes: Any value less than 37 u/ml is considered normal.

Question 5

is there a test that tells if your body is able to produce ca19-9 even if cancer has been diagnosed and shows the level 32 and 33 tested 2x same day?

Accepted Answer

Yes possible: Ca 19-9 production is related to chromosome 19 , when lewis antigen system is  absent that is related to a b o blood groups will not see ca 19-9 , this tumor marker may not  get elevated even in presence of large GI related tumor ( false negative ) , or elevated with out tumor 9 false positive ).

Question 6

diagnosed with stage 4 pan can. treated w/gemcitabine/abraxane combo. pretreatment ca19-9 was 486. now ca19-9 is in normal range.  what does this mean?

Accepted Answer

Temporary control: Stage 4 pancreas cancer only be managed with chemo, that is Folfieri (FOLFOX+ Irinotecan). Following this Gemzar (gemcitabine) + Abraxane gives best control   as noted by normal Ca19.9  used for monitoring  Follow up with serum markers and PET/CAT essential since increase in Ca19.9 suggests need for experimental trial with immunotherapy.

Question 7

Accepted Answer

Nondiagnostic: I don't believe that it's diagnostic of pancreatic cancer in the absence of other supporting findings. Your gastroenterologist is best qualified to advise you,however.

Question 8

can you have pancreatic cancer if the ca19-9 is within normal value 32-33?

Accepted Answer

Diagnosis is: Not based just on tumor marker 19-9 only , require other tests ,  including biopsy is required for definitive diagnosis of pancreatic cancer  0 - 37/ units/ ml  is considered normal , speak to you doctor who has more information on you.

Question 9

Accepted Answer

Not useful: CEA and CA19-9 are tumor markers that can be useful in following the progression or response of a known tumor. Neither is useful as a diagnostic test or to rule out a cancer.
