The mean corpuscular hemoglobin concentration (MCHC) is a measure of the concentration of hemoglobin in a given volume of packed red blood cell. It is calculated by dividing the hemoglobin by the hematocrit. Reference ranges for blood tests are 32 to 36 g/dL (320 to 360g/L), [1] or between 4.81 and 5.58 mmol/L. It is thus a mass or molar ...
Each hemoglobin molecule carries four heme groups; hemoglobin constitutes about a third of the total cell volume. Hemoglobin is responsible for the transport of more than 98% of the oxygen in the body (the remaining oxygen is carried dissolved in the blood plasma). The red blood cells of an average adult human male store collectively about 2.5 ...
If he has microcytosis (mean cell hemoglobin < 27 pg or mean red cell volume < 80 fl), the woman is tested. When both are microcytic, their hemoglobin A2 concentrations are measured. If both have a concentration above 3.5% (diagnostic of thalassemia trait) they are referred to the local designated health post for genetic counseling. [106]
Long-term transfusion therapy (in those with transfusion dependent beta thalassemia) is a treatment used to maintain hemoglobin levels at a target pre-transfusion hemoglobin level of 9–10.5 g/dL (11–12 g/dL in those with concomitant heart disease). [8] To ensure quality blood transfusions, the packed red blood cells should be leucoreduced.
Rather, the advances in cognitive psychology established a groundwork for understanding well calibrated confidence levels in decision making. [ 2 ] Early accounts of explaining analytic confidence focused on certainty forecasts , as opposed to the overall confidence the analyst had in the analysis itself.
