B12 Blood Test Results

[mbb323]

Hi

I am currently on 3-monthly maintenance injections after having 3 x 1 weekly loading doses when diagnosed with low B12 levels 18months ago. Neurological symptoms have continued, including constant dizziness and blurred vision. Then during the first lockdown period I was not contacted by the GP for my injection in August and stupidly

didn't chase this up so did not have next injection until November! By this time I was having quite severe symptons with ocular migraines, "jelly legs", breathlessness, dizziness, nerve pains in arms and legs etc etc. I started taking oral B12 supplements in August and have only felt able to function by taking 3 or 4 1000ug timed release tablets daily., which is a lot! After several recent conversations with my GP I had further blood tests to establish if I had pernicious anaemia. My GP advised continuing the oral tablets and as expected the B12 levels are now over 2000. I am awaiting a phone call to discuss the results (I dont know the result of the IFA test )but I am wondering if anyone can advise if I should be asking for more frequent injections?

Thank you.

PS Basically I am asking if the high blood test results after taking the oral tablets means that my body is absorbing the B12? Thank you

You had an injection in November?

When did you have the blood test that showed high B12?

If your current treatment is not keeping your symptoms away then you need more frequent injections.

Hi

Thank you for the reply. I had my last injection on 9th November (three months late). Was already supplementing with 1 daily oral B12 tablet - the reading then was 408. Due to increase in symptoms I started taking up 4 tablets daily prior to the last blood test on 10th December - results have just come back with reading of 2000+.

Thank you.

One month after an injection I'm not surprised that your levels were sky high.

I’m new to B12 matters. Had initial 6 injections 3 months ago and due booster in 5 days. Last week test showed levels at 500 plus, but from before that test i’m feeling non muscular aches and pains in arms and legs. How long does it take after a B12 booster for the symptoms to fade away, a day or two, days, weeks or more than a month?
