“The hematocrit is a basic, inexpensive screening test for anemia.”
“The hematocrit is the proportion of blood that consists of red blood cells; the lower the hematocrit, the more anemic the patient.”
“One consequence of the extra cells is that the percentage of the blood volume taken up by the cells (the "hematocrit") goes up.”
“The lab measurement for red blood cells is called "hematocrit," and 35% to 55% is considered normal.”
“As to your blood, I’m sure that the 41% is your hematocrit, which is basically a measurement of the volume of your red blood cells in a known quantity of serum.”
“The resulting anemia may be severe enough to require replacement transfusions. 1 A baseline hemoglobin/hematocrit and peripheral smear may be warranted to monitor for the occurrence of hemolytic anemia.”
“Riders who are found to have hematocrit levels of 50 or above are provisionally suspended, pending further investigation.”
“Such an increase can also result in a lower overall hematocrit level, despite the presence of a greater number of red blood cells produced by EPO or introduced by blood doping.”
“While more sophisticated methods of detection have evolved over the years, the UCI still conducts regular hematocrit checks both in and out of competition.”
“Translating hemoglobin to hematocrit can be influenced by body weight and other factors but it is typically three times the hemoglobin count.”
