Hi I am asking a question on behalf of my daughter who has a diagnosis of pernicious anemia .  She had been having regular injections for past couple of years. She asked for print out if latest blood tests and b12 was 1916 .....thus seems very high ..should we be concerned ..results says no action but noted high levels may be seen in haematological and other malignancy . My daughter is 33 and has mild learning problems which is why I am asking on her behalf ..she is also deaf and doesn't always pick up what is being said ...any advice would be much appreciated thanks

    Be assured that you cannot overdose on Vitamin B12 because any excess to requirements is excreted via the urine.

    That your daughter has P.A. and is on regular injections really makes the testing of her B12 levels unnecessary and next to useless unless the result comes back LOW so please don't worry at her high level.

    It is also important that your Folate level is monitored as this is essential to process the B12.

    There is a complex interaction between folic acid, vitamin B12 and iron. A deficiency of one may be "masked" by excess of another so the three must always be in balance.

    Folic acid works closely with vitamin B12 in making red blood cells and helps iron function properly in the body.

    I ma not a medically trained person but have had P.A. myself for 46 years and I'm still "clivealive" and over 75.

    I wish you and your daughter well

      Are you in the UK?

      Serum B12 levels vary depending on which laboratory has done the testing

      However, as you say you have just been diagnosed with P.A your B12 level is likely to be below the "Normal" range and you should be scheduled to have a course of B12 injections.

      Please ask you doctor to check your Folate (Vitamin B9) level as this and the B12 you will be having injected help your iron to function properly and to make red blood cells.

      Come back and let us know how you are getting on or if you have other questions.

      I am not a medically trained person but have had P.A. for more than 45 years.
