If relative polycythemia is deemed unlikely because the patient has no other signs of hemoconcentration, and has sustained polycythemia without clear loss of body fluids, the patient likely has absolute or true polycythemia. Absolute polycythemia can be split into two categories:
There are other names for the hematocrit, such as packed cell volume (PCV), volume of packed red cells (VPRC), or erythrocyte volume fraction (EVF). The term hematocrit (or haematocrit in British English) comes from the Ancient Greek words haima (αἷμα, "blood") and kritēs (κριτής, "judge"), and hematocrit means "to separate blood".
Absolute terms describe properties that are ideal in a Platonic sense, but that are not present in any concrete, real-world object. For example, while we say of many surfaces of physical things that they are flat, a rather reasonable interpretation of what we presumably observe makes it quite doubtful that these surfaces actually are flat.
Hypovolemia, also known as volume depletion or volume contraction, is a state of abnormally low extracellular fluid in the body. [1] This may be due to either a loss of both salt and water or a decrease in blood volume.
Lymphocytosis is an increase in the number or proportion of lymphocytes in the blood.Absolute lymphocytosis is the condition where there is an increase in the lymphocyte count beyond the normal range while relative lymphocytosis refers to the condition where the proportion of lymphocytes relative to white blood cell count is above the normal range.
A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).
This is often measured by quantifying the "AUC". In order to determine the respective AUCs, the serum concentration vs. time plots are typically gathered using C-14 labelled drugs and AMS (accelerated mass spectrometry). [5] Bioavailability can be measured in terms of "absolute bioavailability" or "relative bioavailability".
However, with a reduction in plasma volume, hematocrit and hemoglobin can be increased due to hemoconcentration. [4] Low urinary sodium is commonly found in hypovolemic patients as the kidneys attempt to conserve sodium and water to expand the extracellular volume.
