BLOOD COLLECTION BSC.Shapol habeeb First stage Second lecture Department of Anesthesia 2023-2024 Blood collection: Blood sampling or blood collection method is an essential procedure in modern medicine. The blood can be taken from a vein where it is called venous blood collection or arteries where it is called arterial blood collection. Blood collection techniques: Three popular methods of blood collection or sampling are: Arterial Sampling. Venipuncture Sampling. Fingerstick Sampling. Arterial blood sampling Venipuncture sampling Fingerstick sampling Complication of blood collection The possible risks associated with blood drawing are pain,bleeding,fainting,bruising,infection and/or hematoma (blood clot under the skin) at the injection site. Capillary blood A capillary sample is a blood sample collected by pricking the skin.capillaries are tiny blood vessels near the surface of the skin. Blood sampling: Capillary blood sampling can be used to test for blood glucose (such as in blood glucose monitoring), hemoglobin, pH and lactate. It is generally performed by creating a small cut using a blood lancet, followed by sampling by capillary action on the cut with a test strip or small pipette. Collect capillary blood samples Hold the finger in an upward position and lance the palm-side surface of the finger with propersize lancet (adult/child). Press firmly on the finger when making the puncture. Doing so will help you to obtain the amount of blood you need. Venous blood Venous blood is deoxygenated blood that flows from tiny capillary blood vessels within the tissues into progressively larger veins to the right side of the heart. Venous blood is the specimen of choice for most routine laboratory tests Serium test Serum is the fluid and solvent component of blood which does not play a role in clotting. It may be defined as blood plasma without the clotting factors, or as blood with all cells and clotting factors removed. A total serum protein test measures the total amount of protein in the blood. It also measures the amounts of two major groups of proteins in the blood: albumin and globulin. Albumin. This is made mainly in the liver. Plasma Plasma , also known as blood plasma, appears light-yellowish or straw-colored. It serves as the liquid base for whole blood. Whole blood minus erythrocytes (RBCs), leukocytes (WBCs), and thrombocytes (platelets) make up the plasma plasma in blood Plasma is the liquid portion of blood. About 55% of our blood is plasma, and the remaining 45% are red blood cells, white blood cells and platelets that are suspended in the plasma. Plasma is about 92% water Thank you
