Although the above mentioned findings are the most common use of this test, this test also allows us to gain information on the measurements of the average red blood …show more content…

If there is a increased red blood cell count or high hematocrit should point in the direction of dehydration, most commonly from severe diarrhea. It can also be a marker for increased erythropoietin production, which points to kidney malfunction.

These abnormalities may suggest bone marrow problems as the potential

Bp may be defined as a force of blood against vessel walls in the body, consisting of systolic and diastolic pressure measured in millimeters of mercury. (Waugh and Grant, 2016) Systolic pressure occurs when the hearts left ventricle contracts and forces blood into the aorta causing a heightened atrial pressure, while diastolic pressure refers to complete cardiac diastole, this is when the aortic valve closes and pressure is at its lowest between beats, blood moves into smaller corresponding vessels and the heart rests.

  • Thalassemia Case Study

    Based on this fact, the primary screening method for all forms of thalassemia relies on red blood cell parameters index cut-offs, which involves an accurate blood count using an electronic blood cell counter. A commonly used approach consisted of a complete blood count to assess the MCV and the MCH (Metcalfe, 2007). The finding of a normal MCV (80fL) in combination with a normal MCH (27pg) would rule out most cases of thalassemia and would require no additional thalassemia testing. Individuals with MCV of less than 80fl and MCH of less than 27pg should be examined further to confirm or exclude the diagnosis of both alpha and beta-thalassemia (The Thalassemia Working Party of the BCSH General Haematology Task Force, 1994; A Working Party of the General Haematology Task Force of the British Committee for Standards in Haematology, 1998). Some screening programs rely on the identification of low MCV alone in the absence of iron deficiency (Ronald, 2006; Ashraf, 2004).
