test

I was wondering if a 42.5 was high for a ca 19-9 test.  Is 42.5 high?   The norm was below 35

Hi,
Any laboratory test must be interpreted in the appropriate clinical context. Please provide the important clinical details.
A "tumor marker" blood level may be increased by cancer as well as non-cancer causes.
All the best, and God Bless!

Hi,
Your medical history complicates the interpretation of the Ca19 9 in your case. This tumor marker is seen to be elevated in a number of conditions, including colon cancer, pancreatic cancer, other cancers, and many non-cancerous diseases. Also, this test is known to sometimes give "false positive" or "false negative" results. Another point is that any one report of Ca 19 9 is of limited clinical significance, rather it is the trend (increasing, stable, decreasing) of many serial levels that can yeild some information.
Hence this result of a slightly elevated Ca 19 9 should be interpreted with caution in your case. It must be compared with previous reports, imaging results, results of CEA trends, current stage of your colon cancer, and clinical condition.
Also, it may be worthwhile repeating this test after 4 to 6 weeks.
All the best, and God Bless!
