Pernicious Anemia BMLT DMLT notes

 Pernicious Anemia A decrease in red blood cells when the body can't absorb enough vitamin B12. It is an organ specific auto immune diseases in which the body's immune system attacks the lining of the stomach.It was considered as a deadly disease due to the lack of available treatment. Pernicious anemia is most common in caucasian persons of north European ancestry than in other racial groups. Vitamin B12 Vitamin B12 is a water-solu ble vitamin that keeps your nerves and red blood cells healthy. It is responsible for the smooth functioning of several critical body processes. It helps to form red blood cells. It is found in animal foods including meat, fish, eggs, milk and other dairy products. Causes Intrinsic factor(IF) is a glycoprotein made in the stomach that is necessary for the absorption of vit812. When the stomach does not make enough IF, the intestine cannot properly absorb vitamin B12. As a result it can cause permanent damage to nerves and other organs. Also parietal...

CROSS MATCHING IN BLOOD BANKS BMLT DMLT notes

Image
 Introduction: Cross Matching is a procedure performed prior to a blood transfusion to determine whether donor blood is compatible (or incompatible) with recipient blood. Compatibility is determined through matching of different blood group systems, the most important of which are the ABO and Rh system, and/or by directly testing for the presence of antibodies against a sample of donor tissues or blood. Purpose of Cross Matching The crossmatch is routinely used as the final step of pretransfusion compatibility testing. The purposes of compatibility testing are to detect: irregular antibodies; errors in ABO grouping, and clerical errors in patient identification and result recording. The crossmatch will detect the following: 1. Most recipient antibodies directed against antigens on the donor red blood cells. 2. Major errors in ABO grouping, labeling, and identification of donors and recipients. Principle Cross-matching will detect incompatibilities between the donor and recipient th...

Contents [ hide ]  Objective 1. Describe the basis of blood typing. 2. Know about ABO and Rh system of blood typing and their clinical Significance. 3. Describe incompatibilities ABO and Rh Systems. 4. Know the different types of blood transfusions and their complications ( transfusions reaction ). 5. Describe the basis of the blood typing and crossmatching tests for a safe blood transfusion. Basis of Blood grouping or Typing (Multiplicity of Antigens in the blood cells) At least 30 commonly occurring antigens have been found on the cell membrane of RBCs. These can cause Ag-Ab (antibody) reaction if mixed with plasma that contain Ab against these Ag. According to presence or absence of these antigens blood is classified into several groups or types. Two groups of Ag can cause transfusion reactions more than others: ABO and Rh systems of Ag. ABO System for Blood Typing A and B Antigens Agglutinogens ABO blood types Relative frequency of different blood types: O.    4...

What is the RBC Test?

Image
 This test measures the amount of red blood cells, or erythrocytes, in your blood. Red blood cells play a vital role in transporting oxygen from your lungs to your entire body and returning carbon dioxide to your lungs for excretion. Red blood cell count (RBC) counts are usually performed as part of a complete blood count. This is a diagnostic test for various health conditions. Why You Need Blood RBC Test Done by Specialist? The RBC figure is almost always part of the complete blood count (CBC) test. Tests can help diagnose different types of anemia (low number of RBCs) and other conditions affecting red blood cells. Other situations that may require RBC counts are: Diseases that damage the blood vessels of the kidneys (Alport syndrome) Cancer of white blood cells (Waldenstrom macroglobulinemia) Disorders when red blood cells drop faster than normal (paroxysmal nocturnal hemoglobinuria) Bone marrow disorders in which the bone marrow is restored to red tissue (myelofibrosis) Normal...

Contents [ hide ] Introduction - Causes of High Blood Pressure: The Problem and What You Should Know What is Blood pressure? Blood pressure is a blood pressure that presses against the walls of your blood vessels. Blood vessels carry blood from your heart to other parts of your body. Your blood pressure often rises and falls throughout the day. What do blood pressure numbers mean? Blood pressure is measured using two numbers: The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats. The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart is asleep in the middle of a heartbeat. If the ratio reads 120 systolic and 80 diastolic, you can say, “120 over 80,” or write, “120/80 mmHg.” Normal level of blood pressure Normal blood pressure is below 120/80 mmHg¹.  No matter how old you are, you can take steps each day to keep your blood pressure in check.

Step one The Donation You get to the point where you are nominated for a blood donation. Health history with a slim body is complete. With a complete blood donation, about a liter of blood is collected; Several small blood test tubes are also collected for testing. Your donation, test tubes and donor record are marked with the same bar code label. Your donation is stored on ice before being taken to a Red Cross facility for processing; test tubes go to the laboratory. Step two The Donation Most blood donations are twisted centrifuge to separate components that can be dispensed: red cells, platelets, and plasma. Plasma can be processed into components such as cryoprecipitate, which helps control the risk of bleeding by helping the blood to coagulate. Red cells and platelets are redu...
