B12 Signs & Symptoms Assessment
Wed, 02/17/2010 - 23:20 — hugominney
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.


1.the table may change colour from white to grey to yellow to red - this is meant to happen to illustrate changing status

Axxie - thanks very much for this. Interesting. It struck me that so many of the weird symptoms correlate with weird symptoms of celiac disease! Celiacs don't absorb vitamins well, so have all kinds of deficiencies. B12 is very hard to absorb, so sublingual is good - but shots from the dr. are even better. And, of course, the blood test to monitor your level.

Thanks again, this was informative. : )

Oh I've been pernicious deficience since my 20s. My gut just doesn't want to absorbe with the food I eat. It's hard to monitor your level of b12, if you get a bad lactose intollerent, IBS or a celiac attack you can be sure the numbers aren't going to be high you are better off to shoot yourself.

There is no harm done, as B-12 is water solluble.
The worst that can happen is a sleepless night or two then the body has time to elliminate what it doesn't need and you are fine. I know from experience.

Many peope get this B-12 drop because of how they eat or have bad ibs and that will do it and if they would just get a shot they take care of the problems, especially when you get restless leg symptoms if you get it alot, sure sign you got b-12 difficiency, the pills are for the birds, a shot will go further to take away those sign.

Axxie - this is a such a great post, I keep re-reading it.

Does your doctor give you B-12 shots to keep at home, so you can shoot them in yourself - or do you have to keep going into the office?
