New CEA Roche norms according to age!

[dianetavegia]

The Roche test for CEA now includes a reading for those 40 and older. This is being reported on lab results in other countries but not yet in the U.S.

Test : C.E.A. Method: Electrochemiluminescence - Cobas - Roche Diagnostics For non-smoking patients, the upper normal limit is 3.8 ng/ml (5.0 ng/ml if the patient is over 40 years of age).

For patients who are current smokers, the upper normal limit is 5.5 ng/ml (6.5 ng/ml if the patient is over 40 years of age).

I wrote Labcorp and they said there has been a delay in receiving this information from Roche.

Thanks for the info, Diane. Lois

Interesting info Diane. Thanks for sharing. I wonder what causes the difference with age?

[dianetavegia]

Bumping this.

I wrote Roche and they said the change would have to be approved before it was changed in the U.S. but those are the new numbers for Europe and tests have shown that CEA norms rise after 60 and again at 70 even for those with NO cancer and NO causative factors!

4.9 for 7 months and counting here. Surgeon said he wasn't interested in my cea unless it climbs consistently. Non smoking and under 40. Guess I'm just odd

Interesting. My mum's cea when she has no evidence of disease is a full point higher now she is in her seventies compared to her sixties.
Thanks for info
