Iron Deficiency AnemiaWhat is it and what are its causes?Anemia is an insufficient amount of red blood cells in the bloodstream and iron deficiency anemia is where there is a lack of iron in the blood. You need iron in your blood to make hemoglobin‚ which contributes in distributing oxygen to tissues from the lungs. One of the most common causes of iron deficiency anemia is an inadequate intake of iron in your diet. Another possible cause of iron deficiency anemia is bleeding‚ be this because of

fatigue‚ pale skin‚ protruding abdomen‚ dark urine‚ and abnormal facial bones. The symptoms depend on the type and severity of the disease. These kinds of symptoms typically occur when oxygen is not able to pass in various parts of the body due to low hemoglobin and a shortage of red blood cells in the blood. People with alpha thalassemia trait or beta thalassemia trait usually have no symptoms. But people with alpha or beta thalassemia trait often have mild anemia that may be found by a blood test. Severe

HEMIN TEST Introduction Ludwig Karl Teichmann was a Polish anatomist and physician who made an enduring contribution to forensic science with his discovery of the Hemin test or Teichmann test for hemoglobin. Also called the Teichmann crystal‚ this is a test that is used on dried stains to determine whether or not blood is present. Dr. Teichmann made his forensic discovery in 1853. His microcrystalline test remains in use today as a means of identifying whether or not dried stains at a crime

difficulty. Describe the structure of a molecule of hemoglobin and explain the role played by iron in the transport of oxygen. The structure of hemoglobin is a hemi group. A hemi group consists of an iron (Fe) ion held in a heterocyclic ring. Iron binds with oxygen. Therefore‚ it has a very important role in transporting oxygen in the blood. How is iron stored and transported in the body?1 Approximately two-third of the iron in the body is stored in hemoglobin. The Surplus iron that is not available directly

adult hemoglobin is partially or completely replaced by abnormal sickle hemoglobin(HgbS). Sickle Cell Anemia includes all of those hereditary disorder‚ the clinical‚ hematologic‚ and pathologic features of which are related to the presence of HbgS. Also know as SS and homozygous sickle cell disease. The most common form of SCD are: Sickle Cell Anemia – The homozygous form of the disease (HgbSS) . Sickle Cell –C Disease a heterozygous variant of SCD‚ including both HgbS and hemoglobin C (HgbC)

hematocrits of the Denver residents will be higher than those of the Boston residents. Stop & Think Questions: Why would the hemoglobin levels of an anemic patient be lower than the hemoglobin levels of a normal‚ healthy individual? You correctly answered: c. Because hemoglobin resides in RBCs‚ you would anticipate a low hematocrit level to coincide with a low hemoglobin level.

tagged red blood cell bleeding study was performed in order to localize the bleeding site in case of the necessity of emergency bowel surgery‚ but this proved to show no specific source of the bleeding. The bleeding apparently stopped spontaneously. Hemoglobin and Hematocrit descended to a nadir of 11.9 and 33.7 respectfully the day after admission. The patient’s chronic renal failure worsened steadily‚ with increasing creatinine and BUN and decreasing CO2. At the request of the family no hemodialysis

Understand how the hematocrit (packed red blood cell volume) is determined. 3. Understand the implications of elevated or decreased hematocrit. 4. Understand the importance of proper disposal of laboratory material that comes into contact with blood. Data |Total height of blood column (mm)|Height of red blood cell layer (mm)|Height of buffy

don’t make enough EPO. As a result‚ the bone marrow makes fewer red blood cells. Other common causes of anemia include blood loss from hemodialysis and low levels of iron and folic acid. These nutrients from food help young red blood cells make hemoglobin‚ their main oxygencarrying protein. Healthy kidneys produce a hormone called erythropoietin‚ or EPO‚ which stimulates the bone marrow to make red blood cells needed to carry oxygen throughout the body. Diseased kidneys don’t make enough EPO‚ and
