presence of hemoglobin or its derivatives by the formation of specific crystals. For example‚ the Takayama or hemochromogen test‚ in which ferrous iron from hemoglobin reacts with pyridine to produce red feathery crystals of pyridine ferroprotoporphyrin. Another confirmatory test uses the Teichman reagent‚ consisting of a solution of potassium bromide‚ potassium chloride and potassium iodide in glacial acetic acid‚ and is heated to react with hemoglobin. The reaction first converts the hemoglobin to hemin

Hereditary methemoglobinemia is most commonly referred to as "the blue people disease" or "met-h". It is believed that this disease started in Kentucky with the blue Fugates of troublesome creek. It was started about six generations ago with a man named Martin Fugate. He was a French orphan. Martin came here with his red-headed American bride (Elizabeth Smith). Her skin was as pale as pale could get. They had seven children‚ four of them are believed to have blue colored skin. The clan of them kept

by chronic anemia and periodic episodes of pain. It is one form of sickle cell disease‚ a category of blood disorders caused by defective hemoglobin. Hemoglobin is a substance in all red blood cells that enables them to carry oxygen from the lungs‚ through the bloodstream‚ to all parts of the body (systemic circulation). With Sickle Cell Anemia‚ the hemoglobin in the red blood cells is defective‚ instead of being smooth and donut or disc-shaped‚ the red blood cells become stiff and sickle-shaped

Anemia Anemia is usually defined as a decrease in amount of red blood cells (RBCs) or the amount of hemoglobin in the blood. It can also be defined as a lowered ability of the blood to carry oxygen. When anemia comes on slowly the symptoms are often vague and may include: feeling tired‚ weakness‚ shortness of breath or a poor ability to exercise. Anemia that comes on quickly often has greater symptoms which may include: confusion‚ feeling like one is going to pass out‚ and an increased desire to

then sent to a laboratory‚ where it is screened for hemoglobin S. If the screening test is negative‚ there is no sickle cell gene present. If the screening test is positive‚ further tests will be done to determine whether one or two sickle cell genes are present. People who have one gene sickle cell trait have a small percentage of hemoglobin S. People with two genes sickle cell disease have a much larger percentage of the defective hemoglobin. Sickle cell anemia can be diagnosed in an unborn baby

Physio-EX Blood Analysis: Computer Simulation Introduction In this lab five blood tests will be performed: hematocrit determination‚ erythrocyte sedimentation rate‚ hemoglobin determination‚ blood typing‚ and total cholesterol determination. A “hematocrit refers to the percentage of red blood cells (RBC’s) in a sample of whole blood. Since the function of red blood cells is the transport of oxygen to the cells of the body‚ the higher the hematocrit‚ the more red blood cells are available to carry
