Hello and thanks for posting,

You asked about a private blood test for the 19-9 marker. The 19-9 levels blood test result can be elevated in diseases, (non cancer and cancer) of the pancreas, liver, gallbladder, lung, and urology conditions. Therefore, it is not that useful as a stand alone blood test, except when monitoring already diagnosed conditions.

If you are worrying about symptoms, then you do need to discuss this with your GP who can advise you further.

Best wishes,

Vanda
