Automatic System for Differential Blood Counting

Differential Blood Count (DBC) provides haematologist with valuable information about health of the patient. DBC determines the percentage of types of WBC this is important because it give exact count of five types of WBC such as neutrophil, lymphocyte, monocyte, eosinophil and basophile. Increase or decrease of DBC than the ideal count indicated that our body is not healthy. Precise counting of type of WBC is very important. Manual counting of White blood cells is time consuming and can lead to human error with increase in number of samples. Automatic cell counter sometimes misclassifies the cells having different morphology. Even they are very expensive and unaffordable by remote area health centres and hospitals. These problems are overcome by developing a system which is image based, cost effective, fast and accurate which has the capability to identify, classify the different type of white blood cell and perform DBC. Implementation is done using MATLABR2014b. KEYWORDS: MATLAB, peripheral blood smear, RBC, Thresholding, WBC, DBC. I.INTRODUCTION Total volume of blood in human is 5-6 litres i.e 8% of body weight or 80 mL/kg body weight. -
Understanding the CBC
Understanding the CBC What is Hematology? Hematology is the science of blood and blood-forming tissues. Blood is made up of plasma and blood cells. Blood formation (hematopoesis) is a continuous process that occurs in the bone marrow. Within the bone marrow there is a pluripotent stem cell, the Mother Cell, the originator of all types of blood cells. The stem cell produces blood cells that exit the bone marrow and circulate in the blood system. Red cells circulate about four months, platelets last an average of ten days, and white cells range from only hours to a week or so. Stem cells that are found outside the bone marrow are called “peripheral stem cells” and are collected and frozen for stem cell transplants. What is a CBC? The CBC- the complete blood count, or the counts- is a lab test that will be ordered frequently on your child. This test determines the number, type, percentage, concentration and quality of the various types of blood cells that make up the blood. This test can be completed on blood that is collected by a finger stick, a lab draw from a central vein access and/or a straight draw from a peripheral vein, (usually from an arm, hand or foot). The CBC is commonly performed on an automated analyzer. However when abnormalities are noted in the blood, parts of the test can be completed manually. That is when the blood sample is viewed under the microscope. Some institutions commonly perform an extensively complete CBC and others may perform just specific aspects of the CBC. -

Azathioprine and Mercaptopurine Therapy
Patient & Family Guide 2021 Azathioprine and Mercaptopurine Therapy www.nshealth.ca Azathioprine and Mercaptopurine Therapy Your health care provider feels that treatment with azathioprine (a-za-THY-o-preen) (Imuran®) or mercaptopurine (mur-CAP-toe-pure-een) (6-MP) may help you manage an over-active immune response. This pamphlet will help you decide if this medication is right for you. It describes what azathioprine is, how it works, and possible side effects. What are azathioprine (AZA) and mercaptopurine (6-MP)? • The cells in your immune system fight infection and inflammation (swelling). • If your immune system is over-active, it can can cause inflammation and damage to body tissues and organs. • Diseases that cause an over-active immune response are: › Rheumatoid arthritis › Inflammatory bowel disease (IBD), such as Crohn’s disease and ulcerative colitis › Certain forms of liver disease • AZA is an immunosuppressive medication. It suppresses (weakens) the immune response, which lowers inflammation. 1 • 6-MP is very similar to AZA. It works much the same way, but your body breaks it down in a different way. This makes it less likely to cause nausea (feeling sick to your stomach) and vomiting (throwing up). 6-MP costs more than azathioprine. If you have nausea or vomiting when taking AZA, talk to your health care provider. How well does AZA work? Will it work for me? • AZA, when used alone, helps to control diseases that cause an over-active immune response in many people, including IBD. • Take this medication as told by your doctor. This increases the chance that it will work well. -

Bone Marrow Suppression (Myelosuppression) and Leukopenia/Neutropenia
Effects on the Hematopoietic System: Bone Marrow Suppression (Myelosuppression) and Leukopenia/Neutropenia Effects on the Hematopoietic System: Bone Marrow Suppression (Myelosuppression) and Leukopenia/Neutropenia Author: Ayda G. Nambayan, DSN, RN, St. Jude Children’s Research Hospital Erin Gafford, Pediatric Oncology Education Student, St. Jude Children’s Research Hospital; Nursing Student, School of Nursing, Union University Content Reviewed by: Monika Metzger, MD, St. Jude Children’s Research Hospital Cure4Kids Release Date: 6 June 2006 Leukopenia is a decrease in the absolute number of white blood cells, whereas neutropenia is the condition in which the absolute neutrophil count (ANC) is either < 500/mm3 or <1000/mm3 with a predictable decline to <500/mm3 in 24 to 48 hours. Leukopenia and neutropenia can be caused by cancer or by myelosuppression secondary to therapy (chemotherapy and radiation therapy). Infection is the most common complication associated with neutropenia and the major cause of morbidity and mortality in neutropenic patients with cancer. Important determinants of the risk of infection include the number of circulating neutrophils and the duration of the neutropenia. The lower the number of circulating neutrophils is and the longer the neutropenia lasts, the higher the incidence and the more severe the infections are. Children and adolescents with severe neutropenia (ANC< 500/mm3) are at risk of life- threatening bacterial, fungal and viral infections. If the patient has febrile neutropenia (A – 1), surveillance cultures and more blood tests should be conducted to determine whether infection is present and, if it is, where it is located. Assessment Patient assessment must include a careful history and physical examination. -

Mutations in the thiopurine S-methyltransferase (TPMT) gene causing excessive myelosuppression during 6-mercaptopurine (MP) therapy may cause excessive bone marrow toxicity. We report the case of a 15-year-old girl with T-ALL who developed severe pancytopenia during consolidation and maintenance therapy despite reduction of the dose of MP to 5% of the standard dose. Prednisolone therapy produced a remarkable but transient bone marrow recovery. Analysis of common TPMT polymorphisms revealed TPMT *3A/*3C.

Laboratory Approach to Anemia Laboratory Approach to Anemia
DOI: 10.5772/intechopen.70359 Provisional chapter Chapter 12 Laboratory Approach to Anemia Laboratory Approach to Anemia Ebru Dündar Yenilmez and Abdullah Tuli Ebru Dündar Yenilmez and Abdullah Tuli Additional information is available at the end of the chapter Additional information is available at the end of the chapter http://dx.doi.org/10.5772/intechopen.70359 Abstract Anemia is a major cause of morbidity and mortality worldwide and can be defined as a decreased quantity of circulating red blood cells (RBCs). The epidemiological studies suggested that one-third of the world’s population is affected with anemia. Anemia is not a disease, but it is instead the sign of an underlying basic pathological process. However, the sign may function as a compass in the search for the cause. Therefore, the prediag- nosis revealed by thorough investigation of this sign should be supported by laboratory parameters according to the underlying pathological process. We expect that this review will provide guidance to clinicians with findings and laboratory tests that can be followed from the initial stage in the anemia search. Keywords: anemia, complete blood count, red blood cell indices, reticulocyte 1. Introduction Anemia, the meaning of which in Greek is “without blood,” is a relatively common sign and symptom of various medical conditions. Anemia is defined as a significant decrease in the count of total erythrocyte [red blood cell (RBC)] mass, although this definition is rarely used in clinical settings. According to the World Health Organization, anemia is a condition in which the number of red blood cells (RBCs, and consequently their oxygen-carrying capacity) is insufficient to meet the body’s physiologic needs [1, 2].
