Armstrong to publish anti-doping test results
[SIZE=-1]Mail & Guardian Online, South Africa [/SIZE]
[SIZE=-1]Armstrong said he fears the misreading of his haematocrit (red blood cell count) level -- a biological parameter than can indicate, but not necessarily prove, blood doping -- could be misinterpreted.[/SIZE]

[SIZE=-1]Haematocrit levels are generally in a bracket of 40 to 45, although the legal haematocrit level in cycling is 50.[/SIZE]

[SIZE=-1]The use of banned blood products that enhance performance usually raises the haematocrit level towards that permitted threshold, thus prompting suspicion of cheating. However, haematocrit levels are also known to fluctuate naturally.[/SIZE]

[SIZE=-1]Armstrong said: "Say, for example, hypothetically, it [haematocrit] is 43, 42, 41 and you then go to altitude for a month and it goes to 46.[/SIZE]

[SIZE=-1]"Not everyone in this room is going to say that that means I must have cheated. But a few of you would say it was suspicious." [/SIZE]

[SIZE=-1]He added: "I sat down with one magazine journalist and this guy says, 'our physiologist says it's absolutely impossible for your haematocrit to rise during the season.[/SIZE]

[SIZE=-1]"[But] if you go to altitude training for four weeks or six weeks, you get sick, you get dehydrated. And he's telling me it can't go up? That's ridiculous.[/SIZE]

[SIZE=-1]"When you publish [information like] that ... then you open yourself up to all this other criticism." ...[/SIZE]
