In hematology, thrombocythemia is a condition of high platelet (thrombocyte) count in the blood. Normal count is in the range of 150 × 10 9 to 450 × 10 9 platelets per liter of blood, [1] but investigation is typically only considered if the upper limit exceeds 750 × 10 9 /L. When the cause is unknown, the term thrombocythemia is used, as ...
Complete blood count and blood smear. Basophilia is the condition of having greater than 200 basophils /μL in the venous blood . [ 1 ] Basophils are the least numerous of the myelogenous cells, and it is rare for their numbers to be abnormally high without changes to other blood components.
Leukocytosis can be subcategorized by the type of white blood cell that is increased in number. Leukocytosis in which neutrophils are elevated is neutrophilia; leukocytosis in which lymphocyte count is elevated is lymphocytosis; leukocytosis in which monocyte count is elevated is monocytosis; and leukocytosis in which eosinophil count is elevated is eosinophilia.
Polycythemia in newborns is defined as hematocrit > 65%. Significant polycythemia can be associated with blood hyperviscosity, or thickening of the blood. Causes of neonatal polycythemia include: Hypoxia: Poor oxygen delivery (hypoxia) in utero resulting in compensatory increased production of red blood cells (erythropoeisis). Hypoxia can be ...
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).
Leukocytes. Symptomatic Hyperleukocytosis (Leukostasis) is defined by a tremendously high blast cell count along with symptoms of decreased tissue perfusion.Leukostasis is associated with people who have bone and blood disorders and is very common among people with acute myeloid leukemia or chronic myeloid leukemia.
Concentrations in healthy individuals are usually under 5 white blood cells per μL. Lymphocytic pleocytosis is an abnormal increase in the amount of lymphocytes in the cerebrospinal fluid (CSF). It is usually considered to be a sign of infection or inflammation within the nervous system , and is encountered in a number of neurological diseases ...
When hemoglobinemia is internally caused, it is a result of recessive genetic defects that cause the red blood cells to lyse, letting the hemoglobin spill out of the cell into the blood plasma. In intravascular hemolysis, hemoglobin is released and binds with haptoglobin. This causes haptoglobin levels to decrease.
