It means she almost certainly has Pernicious Anaemia.
How can you an Intrinsic Factor test please NJPoet ?
I had mines done via medichecks private blood tests but you could try asking your gp to test for p.a if you’re worried.best of luck.

Thank you Hidden
You can get an Intrinsic Factor Antibody Test to do at home from Medichecks.com. The cost is £100.00 plus £30.00 to have blood sample taken at a clinic ( its not a finger prick test ) or £55.00 to have a nurse come to your home to do it. Free if you know a professional who can do it for you . I was disappointed that Medichecks don’t point out that one can have Pernicious Anaemia, but not have I.F. antibodies show up .
They also offer what they call a “Pernicious Anaemia blood Test “ for £280.00 , plus costs of having blood taken as above . Also not pointing out that the lack of I.F. antibodies does not rule out P.A.
I’ve always thought that there is no conclusive test for P.A. Doctors mostly assume that you haven’t got P.A. if the I.F. antibody test comes up negative .
Sorry I’m not sure if I’m interpreting the picture correctly but does that result indicate she is in the green zone? Usual with medichecks results they colour the zone you are in so if it was high for instance there would be a red block in that section Kind regards
That’s not a Medicheck test result , which are really easy to interpret. NJPoet is in USA .

PA tests
Intrinsic Factor Antibody (IFA) test

Parietal Cell Antibody (PCA) test
labtestsonline.org/tests/pa...
PCA is not recommended as a diagnostic test for PA in UK.
It is still possible to have PA with a negative result in IFA or PCA test.
About 50% of people with PA test negative on IFA test.
About 10% of people with PA test negative on PCA test.

B12 article from Mayo Clinic in US.
ncbi.nlm.nih.gov/pmc/articl...
Table 1 in above article is about frequent misconceptions about B12 deficiency.
Article suggests ....
1) No proof that oral b12 is a good at treating B12 deficiency as B12 injections
2) Many current tests eg serum b12, active B12, MMA, Homocysteine, are not totally effective as diagnostic tests for B12 deficiency.
3) Successful treatment should not be stopped
