over 3 million people in the United States. It is a medical condition where the red blood cell count or the hemoglobin count is below normal and there are no enough healthy red blood cells to carry adequate oxygen to the tissues. The normal level of hemoglobin in male and females are different. In men a hemoglobin level of less than 13.5 gram/100 ml is considered as anemia and in women hemoglobin of less than 12.0 gram/100 ml is considered as anemia. In the case study provided Ms. A appears to have Iron

common tests we do are CBC (Complete Blood Count)‚ Hemoglobin Electrophoresis‚ and Sickle Cell Test. In CBC‚ we can count the number of red and white blood cells‚ as well as the amount of hemoglobin in the blood. We would need to draw two samples of blood. In your case‚ a sharp tool called a lancet would need to be used because your child would be young. The Hemoglobin Electrophoresis also measures the different types of oxygen-carrying hemoglobin in the blood. We would use the same technique as

Sickle cell anemia (SCA) is a genetic disorder that is hereditary. It affects the blood‚ and is caused when the hemoglobin in blood cells are deprived in oxygen from the proteins. These cause normal round blood cells‚ to have are rigid sickle shape. People affected by SCA have a higher risk of death‚ stroke‚ severe attacks‚ and severe rushes of pain. James Herrick discovered an anemia‚ and found bizarre sickle-shaped cells in 1910. A treatment for the disease was discovered in the 1920s by E. Vernon

a sign that the body has some sort of problem with its red blood cells (RBCs). If a person’s blood does not have the right amount of red blood cells or hemoglobin‚ anemia can develop. Anemia is defined as a decrease in the circulating red blood cell mass and an equal decrease in the oxygen carrying capacity of the blood (also known as hemoglobin). There are many types of anemia that are grouped by their underlying cause. To determine which type‚ doctors describe color‚ size‚ and shape of red blood

African Americans have sickle cell trait; that is‚ they are heterozygotes‚ usually symptomless carriers who have inherited a normal hemoglobin gene from one parent and hemoglobin-S from the other. There are also intermediate forms of the disease that result when a gene for hemoglobin-S is inherited from one parent and a gene for any of several other abnormal kinds of hemoglobin is inherited from the other. Genetic screening is recommended for prospective parents at risk of passing on the disease. If both

characterized by a hemoglobin variant called Hb S. Normal red blood cells are round like doughnuts‚ and they move through small blood tubes in the body to deliver oxygen. Sickle red blood cells become hard‚ sticky and shaped like sickles used to cut wheat. When these hard and pointed red cells go through the small blood tube‚ they clog the flow and break apart. This can cause pain‚ damage and a low blood count‚ or anemia. There is a substance in the red cell called hemoglobin that carries oxygen

HAYMOND‚ PHD uman life depends on the oxygen transport by hemoglobin. In healthy patients‚ the majority of molecular oxygen (O2) is bound to hemoglobin and only a small fraction is dissolved in blood. But in patients with respiratory problems or certain metabolic and genetic disorders‚ the fraction of oxygenated hemoglobin can fall to dangerously low values. Therefore‚ laboratory assessment of oxygen saturation (SO2)—the percentage of hemoglobin saturated with oxygen—provides an important indicator of

sickle cell gene makes abnormal hemoglobin called Hemoglobin-S. The sickle cell gene is a trait due to a change in ONE nucleotide in the DNA sequence that leads to a change in ONE amino acid that changes how the hemoglobin protein folds. This change in the structure of the hemoglobin protein leads to a change in the shape of the red blood cell to a sickle shape. Sickle-cell anemia is caused by a point mutation in the B-globin chain of hemoglobin‚ replacing the amino acid glutamic

Sickle cell anemia is a blood disorder that affects hemoglobin‚ a protein found in red blood cells that helps carry oxygen throughout the body. Red blood cells with normal hemoglobin (HbA) move easily through the bloodstream‚ delivering oxygen to all of the cells of the body. Normal red blood cells are shaped like doughnuts with the centers partially scooped out and are soft and flexible. Sickle cell anemia occurs when an abnormal form of hemoglobin (HbS) is produced. HbS molecules tend to clump together

As a result‚ formation of the corresponding globin chains is trimmed down and an abnormal hemoglobin ratio is enhanced. This abnormal ratio leads to a decreased synthesis of hemoglobin and expression of thalassemia.
