Intrinsic factor antibody test results

[ClaireFa]

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

That's come back as 'normal' Do remember it only picks up about 50% of those with PA

Have you had a vitamin B12 test ? although you can have a normal B12,and still be deficient .

[ClaireFa in reply to wedgewood]

Had b12 and folic acid tests and everything is showing anaemia

[wedgewood in reply to ClaireFa]

Yes , but which sort of anaemia ? Iron anaemia or B12 anaemia , or both ?

[ClaireFa in reply to wedgewood]

Both unfortunately

get the Parietal Antibody Test If positive you have Pernicious Anemia

[Jeep13 in reply to Jeep13]

I agree. Get the Parietal Antibody Test

It can take multiple IFAB tests to return a positive result as it only picks up 50 percent of PA cases. Think of it as those antibodies rising and falling and the test catching it just at the time they rise to be positive.

It is specific for PA, but the anti-parietal cell test is not. My first IFAB test was negative but returned a positive result 7 years later. My antiparietal test returned a negative result.

Hope this helps!

I was negative at first then this year I was positive. I had symptoms for 6 1/2 years and bottom of reference range last year. I hope this helps

Scientist, not medic. It's purely someone being clever, and substituting a chart when a word would have been enough! It's negative. But as Nackapan says, it's only found in half of the PA population anyway.
