or put another way the number or mass of red cells relative to the fluid in the blood that is not Red Cell related. It has recently been used for inpatients to make a noninvasive diagnosis (without floating a catheter in the blood vessel) of Congestive Heart Failure or when fluid is building up in the lungs. That is the simplistic answer as there is a ton of science here to assume with the measurement. One way to use it with Epo would be looking at hemoglobin or Hematocrit measurements as a way of detecting excessive Red Cells that may be brought on by Epo use with Iron. Very Shaky science at best!!! Opinion of mine in next sentence: After you reach a certain red cell number say a hemoglobin of 10 grams that more hemoglobin or a higher number does not translate into ability to run faster or longer.

the TBV test is to eliminate the lower 20 % of horses at sale. Those with below avg blood vol. But if meds are administered to raise the below avg to avg then the tbv test seems pointless.
horse racing is stuck in a serious drug problem, leading to fatalities. i believe all sports have vast amnt of cheaters, just my opinion. regardless, my yearling will be drug free and healthy at the time I part company with him. Last edited by sumitas : 05-14-2008 at 11:49 AM.

Chuck EPO is not the answer to cheating of consequence. It takes way too long to take effect to a level that would actually influence oxygen delivery leading to performance enhancement. While the effect is not titratable....The avoidance of anaerobic metabolism or threshold is how they do it with designer meds that have markers that are unique to them by testing methods.
All they would have to do is change the molecule with one different chemical moiety (eg an extra carbon or hydroxyl group) and the authorities couldn't test for the drug. These are old concepts and why we love ya cause you don't mess with this garbage for your horses.

Didn't the Ledford duo ( Meadowlands harness trainer/driver) get caught with E.P.O. and Morphine? They went away for a while. Maybe Eric is around a little bit now. I heard Vladimir Cerin (in an interview at Santa Anita) say he took blood out, and then put it back in (a few days before a horse raced.) That was like in the early or mid 90's.

Do you think the two are related? And how do you define "healthy"? If he/she is sick, will you not medicate or are you referring only to "performance enhancing" drugs. I would hope you aren't equating how you raise a yearly to those families that heal through prayer, refuse medication and their child dies.

but I dont know how it translates to horses. People with good endurance can have an unexpected low hematocrit. It happens because they have a high blood volume specifically the serum, not RBC's which are also high, but get diluted by the liquid. The high blood volume is probably from extensive capillary volume associated with a very good mechanism for getting blood to and from muscles. In other words, your muscles are so loaded with capillaries, your blood volume is high. There is more tubing to hold more blood. I had this happen to me when I was in very good shape from running. The doc's were scared at first, but I went to a Doc who was a runner and he said he had seen it before. Then I find out about half the people I run with that are really in shape have got the same readings; Low hematocrit, because the liquid portion of the blood is so high, even though they actually have more RBC's than they would out of shape with a normal hematocrit. So it MAY point to horses that have a more extensive circulatory system. This is all conjucture. I agree with the poster about EPO being a big unknown. In fact I can see it being a hindrance(my opinion based on a number of factors)
