TV, don't worry, the post was really just to try to explain the relevance, or rather the lack of it, in the link given in the previous post and the fact that neonates have a different form of Hb from older babies and children. This is not mentioned in that link. I assume that article was written for people with some medical knowledge. My own feeling is that it is a prime example of how those without appropriate knowledge can be seriously misled by information on the internet and in turn can mislead others with perhaps fatal consequences. I should, perhaps have explained myself a bit better.
