 ANEMIA Overview  Anemia is a condition in which you lack enough healthy red blood cells to carry adequate oxygen to your body's tissues. Having anemia can make you feel tired and weak. There are many forms of anemia, each with its own cause. Anemia can be temporary or long term, and it can range from mild to severe. See your doctor if you suspect that you have anemia. It can be a warning sign of serious illness. Treatments for anemia range from taking supplements to undergoing medical procedures. You might be able to prevent some types of anemia by eating a healthy, varied diet. Types Aplastic anemia Iron deficiency anemia Sickle cell anemia Thalassemia Vitamin deficiency anemia Symptoms Anemia signs and symptoms vary depending on the cause. If the anemia is caused by a chronic disease, the disease can mask them, so that the anemia might be detected by tests for another condition. Depending on the causes of your anemia, you might have no symptoms. Signs and symptoms, if they ...

  What Is Esr Test? An erythrocyte sedimentation rate (ESR) is a type of blood test that measures how quickly erythrocytes (red blood cells) settle at the bottom of a test tube that contains a blood sample. Normally, red blood cells settle relatively slowly. A faster-than-normal rate may indicate inflammation in the body. Inflammation is part of your immune response system. It can be a reaction to an infection or injury. Inflammation may also be a sign of chronic disease, an immune disorder, or other medical condition. Other names: ESR, SED rate sedimentation rate; Westergren sedimentation rate. Why Esr Test Is Done? ESR test verifies the presence of one or more types of conditions, including infections, tumours, inflammation, and those leading to the breakdown or decreased the function of tissue or organs (degenerative), and/or to asses the progress of disease or effect of therapy. ESR helps in identifying two specific inflammatory diseases, temporal arteritis and polymyalgia...

  What is Gram Staining? Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents. The Gram stain procedure distinguishes between Gram positive and Gram negative groups by coloring these cells red or violet. Gram positive bacteria stain violet due to the presence of a thick layer of peptidoglycan in their cell walls, which retains the crystal violet these cells are stained with. Alternatively, Gram negative bacteria stain red, which is attributed to a thinner peptidoglycan wall, which does not retain the crystal violet during the decoloring process. How Does Gram Staining Work? Gram staining involves three processes: staining with a water-soluble dye called crystal violet, decolorization, and counterstaining, usually with safanin. Due to differences in the thickness of a peptidoglycan layer in the cell membrane between Gram positive and Gram negative bacteria, Gram positive bacteria (with a thicker peptid...
