68.1 pmoI/L

[Salis80]

My test results shows active B12 of 68.1 with Normal range 25.1 - 165.0 pmol/L. My GP says it's normal and won't do anything. Can any tell me whether this is low or high?

[Nackapan]

It seems to imply anything below 25.w is low.Yours looks well kntk range.

A result of 68.1 I would consider quite good. As a comparison mine is 27!!!

Getting things tested is only a small part of the equation. If you can't interpret the results, and don't wish to believe your GP, then ask yourself why you spent money on having them done in the first place!

Good luck.

hello Salis80, I personally think 68.1 is a bit low.

But it is really dependent upon your symptoms.

Range are set low to avoid treating us to save money. Ranges for private tests are also set too low.

[FlipperTD in reply to Wheat]

Hi. I'd like to see some evidence for your statements on reference ranges and money saving.

The reference ranges I produced were based on actual test results.

[Wheat in reply to FlipperTD]

Flipper, thank you for your reply. I am pleased to inform you that my posts are based on careful, verifiable, reputable research. I am sure you can appreciate it would be inappropriate and unfeasible to produce it here.

However, perhaps you did not realize your reply to me could be viewed as challenging and potentially undermines my reply to the original post.

Speaking generally, Health is an important matter so helpful and factual responses is important, but not critical and flippant off hand reponses.

Best wishes for your health

I spent my scientific career being challenged, and challenging others, for evidence. It could get tedious but if anyone started wandering off the point they were brought back in line, regardless of who they were. [Yes, there are stories but best not shared on here.]

I have yet to come across anyone publishing a reference range based on cost saving rather than a statistical approach and either Gaussian or Skewed distributions, but I'm not suggesting it doesn't happen. Just that I've never seen evidence for it.

Be healthy, and keep up the research!

[FlipperTD in reply to Wheat]

Further to my earlier email, trust me; I did realize that my reply could be viewed as challenging. That was my point. Otherwise I wouldn't have bothered replying.

If you have evidence from your research that reference ranges are being manipulated to avoid treating us and saving money, and the ranges for private tests are also being manipulated, then this is actually a very serious matter indeed.

Ranges are broad and imprecise and now take the place of symptoms. Go by symptoms.

For comparison, the active b12 test here in Australia says that below 60pmol/L is borderline low. Mine was 56 and my total B12 was 172. And I had symptoms. The whole picture is important too
