What Is Easy Bruising? Ecchymosis, or easy bruising, is a feature of impaired secondary hemostasis (blood clotting) characterized by subcutaneous bleeding (under the skin) in response to light trauma. Q: What causes easy bruising? A: Easy bruising is the direct ...

What Is Atherosclerosis? Atherosclerosis is a disease of arteries involving the buildup of fatty material called plaque along the walls of medium and large arteries characterized by patchy subintimal thickening, hardening, and loss of elasticity of blood vessels. The intima is the ...

What Is Transient Erythroblastopenia? Transient erythroblastopenia is a rare disorder of red blood cell formation characterized by brief, reversible disappearance of erythroblasts (red blood cell precursors) in the bone marrow of children. Q: What do the red blood cells look ...

What Is Neutropenia? Neutropenia  is a blood disorder characterized by presence of an abnormally low number of neutrophils. Neutrophils are white blood cells (leukocytes) that serves as the primary defense against infections by destroying bacteria in the blood.  Specfically, neutrophils are ...

What Is Immune Thrombocytopenic Purpura?

What Is Hypoprothrombinemia? Hypoprothrombinemia is a deficiency of prothrombin (clotting factor II) in the blood that is characterized by impaired hemostasis in response to trauma or a laceration. Q: What is hemostasis and how is it altered by a deficiency of prothrombin? A: Hemostasis ...

What Is Hemochromatosis? Hemochromatosis, also called iron overload liver disease, is a common inherited disease in the Caucasian population that is characterized by increased iron deposition within the tissues (overload) associated with injury to them.

What Is Macrocytosis? Macrocytosis is a blood cell disorder characterized by altered blood cell formation that results in abnormally large erythrocytes (red blood cells) circulating in the bloodstream. The mean corpuscular volume (MCV), which is a measure of the size of ...

What Is Macroamylasemia? Macroamylasemia is an acquired enzyme disorder that causes elevated levels of the enzyme amylase (hyperamylasaemia) in the bloodstream. It is characterized by altered amylase molecules that have become abnormally bound with plasma proteins in the bloodstream, commonly ...

What Is Hypophosphatemia? Hypophosphatemia means the level of phosphates in the bloodstream is too low to meet metabolic needs of the body for this mineral. Q: How important is phosphorus in metabolism? A: Phosphorus is crucial to  life, being present ...

What Is Hypoglycemia? Hypoglycemia means the level of glucose within cells is too low to meet metabolic needs of the body for this essential sugar. Q: What are the metabolic needs for glucose? A: Glucose is the most important simple ...

What Is Hypocalcemia? Hypocalcemia, or low plasma calcium, means the level of calcium in blood is too low to meet metabolic needs of the body for calcium. Low blood calcium is characterized by bone and tooth demineralization (loss of calcium ...

What Are Elevated Liver Enzymes? Hypertransaminasemia is a chronic condition of elevated blood liver transaminase enzymes, commonly called “liver enzymes,” that signifies hepatocellular (liver) injury. Q: What are serum transaminases? A: Transaminases are the liver enzymes ALT and AST. ALT is the ...

What Is Hyperprolactinemia? Hyperprolactinemia is an excess secretion of prolactin hormone causing an elevated blood level that is characterized by its effects on reproduction: in females causing  amenorrhea and in males causing reduced sexual potency. Q: What is prolactin? A: ...
