On a very hot day hiro has been outside doing heavy work and just colapsed. if you took blood sample right now his hamatocrit would be higher or lower than his usual hematocrit value?

Which sex has a higher hematocrit generally?
Hematocrit will be present generally in everybody body,but adult female as higher hematocrit. Range of 42% to 52%.
What is Hemoconcetration?
Depletion of the fluid component of blood, making the hematocrit percentage higher.
How does an individuals hematocrit correlate to the erythrocyte count?
The hematocrit is also called the erythrocyte volume fraction, which is the percentage by volume of red blood cells in the blood. Erythrocyte is another name for the red blood cell in humans, so the higher the count, the larger the hematocrit.
What is the difference between men and women having hematocrit?
Definition: Hematocrit is the percentage of blood that consists of red blood cells.HematocritReflects oxygen carrying capacity. It is the percentage of blood that is RBCsMen - 43% to 49%Women - 37% to 43%Men have a higher hematocrit because they have a greater muscle mass
Is there a connection between hematocrit and peripheral edema?
usually peripheral edema is cause by right sided heart failure . people with COPD have polycythemia , means high level of RBCs , means high level of hemoglobin . when hemoglobin is high , hematocrit is high also . People who have a high hematocrit count may be at higher risk for heart problems
Is hematocrit test used for clotting?
Not precisely. It is a means for testing vascular leakage. It is a measure of packed cell volume in the blood. Upon hemorrhage or edema, fluid leaks from the blood vessels (capillaries) and hence creates a scenario of higher cellular content in the blood which is read out using a centrifugal blood packing assay. The higher the hematocrit, the higher the fluid loss into surrounding tissues. The classical clotting time assay is usually a fibrin/fibrinogen activation and/or measure.
Is there any different between blood circulation in male and blood circulation in female?
No. Males tend to have a higher blood volume and hematocrit though.
How does dehydration effect hematocrit?
Hematocrit is the concentration of cells in the blood, measured by the relationship between the cells in the blood (red and white) and the liquid part of the blood called plasma. Normally the less amount of liquid in the body the fewer amounts there will be in the blood itself, therefore the cell/plasma ratio will decrease making the blood more concentrated. That's why the bigger the dehydration, the higher the hematocrit.
How much blood loss required for transfusion?
Current transfusion medicine guidelines do not recommend transfusion of red cells in patients with a hemoglobin of 7 g/dl or higher or a hematocrit of 21% or higher IF their underlying medical status is stable (adequate cardiovascular/pulmonary reserves) and they are not not actively bleeding. Each 500 ml loss of whole blood is expected to decrease the partients hemoglobin by 1.0 g/dl and the hematocrit by 1-3%.
What test would hemoconcentration affect?
Hemoconcentration typically affects blood tests that measure the concentration of various components in the blood, such as hemoglobin, hematocrit, and electrolytes. It may lead to falsely elevated results due to a decrease in the plasma volume, causing the concentration of these components to appear higher than they actually are.
When the concentration is higher on the outside of the cell it is?
Hypertonic solution.
What are the causes of high hematocrit count?
Hematocrit is a measure of the percent of red blood cells in the blood (plasma + RBC). So the more red blood cells the higher the hemoglobin content. It is a linear relationship not a cause and effect.
