Complete Blood Count with Differential is one of the most commonly ordered tests for routine check-ups and/or physicals. A complete blood count with differential measures the levels of red blood cells, white blood cells, platelet levels, hemoglobin and hematocrit. Most of the time it is ordered as a screening test to check for anemia or infection. The Complete Blood Count with Differential is used to aid in diagnosing and treating a large number of conditions (Lockwood, 2013). The Complete Blood Count (CBC) with Differential test involves a blood draw by a qualified lab technician.
This test measure the number of red blood cells, white blood cells and platelets as well as the amount of hemoglobin, a protein in red blood cells. Results may indicate anemia, which commonly occurs in lupus. Erythrocyte sedimentation rate. This test determines the rate at which red blood cells settle to the bottom of a tube in an hour. A faster than normal rate may indicate a systemic disease such as lupus.
When a person’s body produces red blood cell below normal, or less hemoglobin, a condition called anemia develops. NIH (2013) further states that, people with gene disorder of Thalassemia can present with mild, moderate, or severe anemia. Causes Thalassemia occurs when genes that controls the way the body produce hemoglobin are absent or altered (NIH, 2013). The human body makes red blood cells, white blood cell, and platelets. As earlier mentioned, red blood cell contain hemoglobin.
White blood cells fights any infections and diseases in and out the body 3. Platelets which clots the blood to help a person from bleeding to death The formed element travels the body by floating in the plasma. Plasma which is the liquid form of blood that travels through the body. It is like a transport that carries blood Nutrients, proteins and hormones to the cells 3. List the properties of the blood: Volume (male & female), pH, temperature.
Also, lymphocytes can tell when when cells are cancerous or infectious. Lymphocytes are agranulocytes. Eosinophils release toxic substances, and can cause asthma and allergies when they over act and are mass produced in the body. Eosinophils make up 1-6% of white blood cells. Eosinophils are granulocytes.
One method of diagnosis is through a blood test. Blood tests are capable of sorting through the material found in blood, and if heart cell contents are found in the specimen, a heart attack can be diagnosed. If the levels of the cell contents are higher, this signifies that the heart attack is more severe. Another method of diagnosis is an electrocardiogram (ECG). An ECG measures the rhythm of the heart in order to detect defects.
Leukemia Leukemia is a group of blood diseases characterized by cancer of the blood forming tissues. It was discovered in Europe during the XIX century when a group of doctors directed by John Hughes Bennett tested their patients and discovered their elevated number of white blood cells. It was then called “white blood” and later was named leukemia from the words greek words “leukos” (white) and “hemia” (blood). Leukemia is a disfunction of the bone marrow stem that over produces white blood cells which generally infiltrate into other organs spreading the disease to the liver, nervous system, spleen and other organ tissues. The production of white blood cells affect the blood clotting process which means patients who suffer leukemia may present abnormal bleeding or brusing.
A small sample is also saved for further reference if needed. For the bags of red blood cells they must be refrigerated and kept between 4°C and 8°C if the temperature fall out of this range the cell will lose their integrity. How the product/s are prepared Platelets like the plasma and red blood cells are collected from whole blood by centrifuging. But the major way that platelets are collected is by apheresis where as the blood is being drawn it is centrifuged and the platelets are collected into bags and the rest of the blood is then transfused back to the donor. The process may take up to an hour but these donations can be performed at 2-4 week intervals because the red blood cells are returned to the donor.
Table 2 Sample 1 Sample 3 Sample 4 Sample 5 Blood type A+ B+ B- AB+ Overall blood typing techniques were studied during this lab and students became familiar with blood types and the way to identify them. All members of study group followed the procedure in order to avoid cross contamination so the results are considered to be accurate. This lab provided great visualization of agglutination and improved understanding of this process. Overall blood typing has wide application in healthcare setting. Examples can be blood typing done before blood transfusion, during pregnancies or blood typing for research and better understanding of blood related disorders.
