Document Summary
**1 blood test does not equal a diagnosis! Complete blood count (cbc): total cell count in a person"s blood: wbc: 4,000-10,000/ mm3, rbc: 4. 2- 5. 9 million/ mm3. This value represents the total rbc count. Values expected with: hemorrhage, anemia (which also indicates low 02 perfusion to cells) **when rbc, hemoglobin, hematocrit are low = hemorrhage: hemoglobin: males 14-18g/ dl; females 12-16 g/dl. Will never see elevated levels, but is of concern when low. Be careful with low values b/c this could be misleading. Values expected with dehydration and high altitudes: rdw: red cell distribution width- 11. 5- 14. 5, platelet count: 150,000-400,000 mm3. Platelets are located in the bone marrow and the liver. If you have a major trauma to the liver/cirrhosis you will see platelets. Platelets = clotting, dvt, autoimmune: wbc differential: value = infection/ blood cancer; value= chemo/ hiv (isolate pt) Are the first responders to infection (bacterial, some viral, inflammation)
