Additional details about the stuff that Mørkebjerg wonders about.
Apart from the hematocrit/haemoglobin spike, the
reticulocyte values also puzzle Mørkebjerg.
Brief summary of Mørkebjergs comments:
He points out that off season, the values lie around 1%, which quite normal. But come Tour time, the reticulocyte values have fallen to half that - 0,5%. Firstly, Mørkebjerg notes that this is borderline for a normal, healthy person. Secondly, he observes that this indicates that Armstrong's body has halved its own production of red blood cells, which is a significant drop off.
This usually only happens at times when the body has an excess of red blood cells and is often seen with EPO usage or blood transfusions, though he of course points out that this is not proof that this has occured in this instance.
He notes that Armstrong's values are more or less as one would expect that they should be during the Giro. His Hct and Hgb values fall as they would be expected to, and his Reticulocyte vary from 1,3% over 0,7% to 0,9%.
It is the TdF results which he finds unusual, both in their own rights, as well as in comparison to the Giro numbers:
1. No decrease in Hgb/Hct by the end of the race (the earlier reports also noted the variations coinciding with the rest days).
2. Extremely low reticulocyte results. They were down to 0,5 by the start of the race, rose to 0,7% after the first week of the race and then went down to 0,5% again after the first rest day. At the end of the race, they had once again risen to 0,7%.
