Experiences with

Intrinsic factor test

I have recently had the result of an Intrinsic Factor test. The normal range is listed as between 0 - 6 u/mL Mine was 480 u/mL Is anyone able to advise the relevance of this please as it appears quite extreme. Thanks

hi all, I have been experiencing a number of health issues recently and have had an Intrinsic factor antibody test. Please see photo for result, is this a positive or negative result? I am so poorly and just looking for answers. Any words of wisdom would be appreciated

Hi, I've had one Intrinsic factor test before which came in under range. I know its a test that can take a few times to show up.pisitive & kick myself for not trying it again before this loading dose.

I know this isn't uncommon from what I've read on here i just don't understand the doctors logic, I think it's because I had a negative intrinsic factor test ages ago, can absorbtion issues still be a problem even if I don't have PA?

I had a blood test and got the result today - I haven't a clue what this means?? Any ideas? Intrinsic factor antibody level Intrinsic factor antibody level < 0.5 U/mL [0.0 - 6.9]; Negative <7 Equivocal 7 - 10 Positive >10 I can't even work out which part of the above is the result? I receive B12

My GP agreed to do an intrinsic factor antibody test. The test he did was IgA and the results came back as within normal range.1.10gl normal range 0.8 to 4.0 . Was this the correct test for pernicious anemia? Thank you

Apparently my b12 is normal (359) still waiting on intrinsic factor test to come back. Thanks

recently had the Intrinsic Factor Antibody test and Paretal antibody test. IF antibody was unequivocal and the Paretal AB test was positive. Ii was immediately diagnosed with Pernicious Anemia. It took 3 years to get diagnosed.

Hi, In May 2021 I had the intrinsic factor blood test and my results were as follows. 89 u/ml. With a normal range of 0-24 u/ml. And the following notes.

How long does it take for NHS to run this test? I had the test done last Tuesday, but the results are still not showing on my records.

I seem to be at a sticking point with the findings of the intrinsic factor test. This is due to the way they now interpret the test results. My test result was Au/ml 1.63 ... Which I jumped with joy over as I thought "at last, this proves I have been telling the truth". How wrong I was.

Very low B12, below limits of the test, but no antigens to intrinsic factor and negative on caeleac disease. Cant fault the GP but feels very limited what they will provide, essentially case closed 3-monthly b12.

Hi Everyone, Im a bit out of my depth here and wondered if you could help please. Ive taken B Complex for nearly 25 years, I do wonder whether serum levels have always been scuppered, as I read again that to do a credible PA , MMA test I needed to be off B12 for minimum 4- 6 moths , possibly longer

A vitamin b12 blood test said bad intrinsic factor and this must mean pernicious anaemia with a regular injection of b12. Ive had these three or four times and still dont feel right. Can anyone tell me the answer to my question?

Hi, my GP recently stopped my B12 injections which I have been having every 3 months for the past year as my intrinsic factor test was negative.

How do you know if your intrinsic factor antibody blood test is good or bad?

I was diagnosed back in Feb this year after my Intrinsic Factor blood test came back positive and I was diagnosed with Pernicious anaemia. I went to the drs with symptoms of exhaustion, pins and needles, heart palpitations and nausea as well as brain fog.

Hi,good day all,I am confused whether I have P.A.or not.My intrinsic factor test came back as negative but reading other people's post I am not sure is that the test that determines whether you have P.A.or not...In a nutshell what is the test that determines whether you have P.A or not..thanks

So I was eventually given an intrinsic factor test. But all this only surfaced when I’d suffered a minor stroke late August this year, and was admitted to hospital for 4days.

I am still awaiting the Intrinsic Factor Antibody blood test results from my GP, which is now over four weeks.
