Giving You Back YOUR Life

B12 Signs Symptoms Assessment

The table below allows you to enter your signs and symptoms and immediately read off your B12 deficiency status (in the boxes at the start and end).

It was developed by Dr Chandy over decades of caring for patients, and has been found to be extremely reliable. We recommend that you follow up with a blood serum B12 test; this means that you can document your B12 deficiency status (threshold 200ng/L); on the occasions when the table below indicates B12 deficiency and yet total blood serum B12 test returns a reading above 200ng/L, we have observed that the blood serum B12 levels will fall soon after.  Total blood serum B12 is known to be a poor indicator of B12 deficiency status, and we are investigating a test for active-B12.  See also the Symptoms pages

NOTES:

  1. the table may change colour from white to grey to yellow to red - this is meant to happen to illustrate changing status
  2. the table is written in JavaScript.  if you have disabled JavaScript then you should download the document in Adobe Acrobat format
  3. this page does not save your score. If you wish for a permanent record, please print off the form

Donna, like so many women, wants to live a normal life. Vitamin B12 could give her that chance.
The local MP (Grahame Morris MP for Easington - who was a BMS (BioMedical Scientist) in the labs at Sunderland Royal Infirmary) interviews people with B12 deficiency to hear their story (August 27 2010). Here Jane describes the symptoms, and how she can't wait for her next B12 injection (in fact, she knows that she needs injections every 2 weeks because she's keeping a diary of the symptoms). We're restricted how often the GP can give injections, which is why we want to raise awareness.
The Scottish Parliament discusses Pernicious Anaemia and vitamin B12 deficiency on Wednesday 7 March 2012.
This video is over 1 hour long and represents real political change - we are at last on our way.
Just the way it works for humans, oral B12 can make a world of a difference for your pet. My old cat Smudge chases the young cat again, climbs ladders (and climbs down herself), and is generally as fit as she was many years ago.

Dr Chandy was nominated for the North East Local Heroes award. The interviewer was at first surprised - people don't get awards for doing what they are paid to do - but she persisted.
Frankie tells of how she suffered, the tests she had to endure until doctors worked out what was wrong, and what a difference it has made.
Susan gets very tired, which isn't much fun especially as she has so much to do. Here she tells her story.
