How long does it take for MMA blood test results

Posted , 6 users are following.

For the past 18 months I haven't felt right to start with it was tiredness, occasionally feeling sick and lightheaded but back in July while eating my dinner my chin and one side of my face went numb. Since then i have suffered every day with all of the symptoms connected to b12 deficiency. I have has several serum b12 tests which always come back in the normal reference range but at the low end. 263 pg/ml, 320 pg/ml and 268 pg/ml my GP has said that as my levels are in the normal range deficiency is impossible. i also suffer with my stomach which has led to weight loss. ive had MRI scans, countless blood tests, 24 hour ECG and various other tests which have all come back clear or normal. The only thing that was picked up was a vit D deficiency which my GP said was causing all of my symptoms, this has now been corrected and my levels are back to normal but i am still very unwell and none of the symptoms have gone. I collapsed while in with my GP and she reluctantly agreed to test my b12 again along side MMA after i practically begged her to carry out the test.

i am really struggling have been signed off work for the last 6weeks and my period makes everything worse.

i had the MMA blood test over 2 weeks ago and wanted to know if anyone knows how ling this test takes to come back as i am struggling to cope now.

    A normal B12 serum test might be in normal range but that does not been your not deficient. Check out the NICE guidelines in relation to B12

      Thank you for your reply. I have tried telling them about other countries and i've done hours of research which i have shown them but they still say its not b12 and must be something else. Really don't know what else to do as i cant cope worth this much longer its taken over my life.

      Have you noticed a difference since having the injections ?

    are you based in the UK? If so contact the Pernicious Anemia Society. They are great source of information and will give you information to take to your doctor. This is often misdiagnosed and treatment not given when it should be.

    Are you vegetarian or vegan as this can lead to having low b12 levels

    And have they recommended you to have an endoscopy due to your stomach issues? I'm currently on b12 shots every 3 months and started having stomach issues, went for an endoscopy and they found inflammation and erosions.

    I have an appointment in January to get results.

    If your b12 is low but its not diet related it could also be linked to gastritis?

    Maybe worth asking for a second opinion if your not happy with what your current doctor has said

    I hope you get sorted soon

      Thanks for your reply.

      I dont follow any particular diet and i'm not veggie. I have a colonoscopy and an endoscopy booked in for late December to see whats happening with my stomach.

      I went back to the doctor for a second opinion yesterday as i'm now suffering one sided facial and limb numbness on and off every day along with all of the other main symptoms of b12, weakness, tiredness, lightheaded and dizzy the list goes on. I was told yesterday that its all in my head and its impossible to be deficient if the b12 blood test comes back normal.

      No idea what to do now! my MMA blood test still is not back and that was taken over 3 weeks ago.

    It's good you have the tests booked in as this could shed some more light into what is happening.

    It's must be frustrating as your levels are in normal range just at the low end, have you had your iron levels tested? This can also cause fatigue and dizzyness etc

    I haven't suffered with facial numbess before, but I did in hands and feet, annoyingly I still slightly suffer with all symptoms despite b12 now being in the 900 range.

    Would it be worth taking over counter b12 tablets? Think you can get them from a chemist for around £1.

    Sorry your results arnt back, unfortunately I haven't had them done before but would have thought they should have been back by a week... Did they not give you any indication of how long they should take?

      Thanks for responding and sorry to hear you are still suffering the symptoms.

      My iron levels have been checked and they are normal. I am worried about taking any b12 tablets until they have finished testing as I've read that it can affect them.

      Just have to hope the MMA blood test come back soon and wait for the colonoscopy and endoscopy in a few weeks time. Just seems to take forever to get any results. I hope it all goes okay for you in January.

    I dont think B12 tablet work in the same way as injections. If the issue is with absorbtion then tablets wont work.
