Low levels indicate bleeding or increased destruction of RBCs. • hemoglobin test (H, Hg, HGB)- Low levels effect the bodies ability to carry oxygen to the tissues. • partial thromboplastin time (PTT) – ability of blood to clot 58 Laboratory Blood Tests (cont’d.) • platelet count • prothrombin time (PT) • red blood cell count (RBC) • red blood cell morphology • white blood cell count (WBC) • white blood cell differential 59 Clinical Procedures p. 524 apheresis: Separation of blood into component parts and removal of a select part from the blood. blood transfusion: Whole blood or cells are taken from a donor and infused into a patient. 60 61 Clinical Procedures bone marrow biopsy: Microscopic examination of a core of bone marrow removed with a needle. hematopoietic stem cell transplant: Peripheral stem cells from a compatible donor are administered into a recipient’s vein. (Bone Marrow Transplant) 62 Stem Cell Research • Stem Cells are crucial to develop organisms. They are nonspecialized cells which have the potential to create other types of specific cells, such as blood-, brain-, tissue- or muscle-cells. • Some types of stem cells may be able to create all other cells in the body. Others have the potential to repair or replace damaged tissue or cells. 63 • 64 Stem Cell Transplant 65 Abbreviations – See page 525-526 66 REVIEW SHEET COMBINING FORMS Combining Form • • • • • • bas/o chrom/o coagul/o cyt/o eosin/o erythr/o Meaning base color clotting cell red, dawn, rosy red 67 REVIEW SHEET COMBINING FORMS Combining Form • • • • • • Meaning granul/o hem/o hemat/o hemoglobin/o is/o kary/o granules blood blood hemoglobin same, equal nucleus 68 REVIEW SHEET COMBINING FORMS Combining Form • • • • • • leuk/o mon/o morph/o myel/o neutr/o nucle/o Meaning white one, single shape, form bone marrow neutral nucleus 69 REVIEW SHEET COMBINING FORMS Combining Form Meaning • • • • • phag/o poikil/o sider/o spher/o thromb/o eat, swallow varied, irregular iron globe, round clot 70
