during the 1st year of life (Lenfant, 2002). The first is the splenic sequestration crisis, an unpredictable pooling of large numbers of RBCs in the spleen, which leads to a rapid decrease in hematocrit and, in the most severe cases,cardiovascular collapseand death. The second is overwhelming...
The inheritance of a single mutant gene results in the carrier state, characterized by a mild microcytic, hypochromic anemia and a slightly elevated concentration of hemoglobin A2. Coinheritance of thalassemia mutations with hemoglobin S will produce sickle cell disease, whereas coinheritance of ...

The ferritin blood test can detect elevated or low levels of ferritin in the body, which may indicate disease such as hemochromatosis, rheumatoid arthritis, certain cancers, anemia, or iron deficiency. Hematocrit Ranges (Normal, High, Low) Hematocrit in the blood is the proportion of the blood ...
The blood samples were transferred to the laboratory and through the colorimetric method, the mindray BC 20 was used to estimate the total hemoglobin concentration of the sampled blood. The value of the hemoglobin level was compared to the value of the hematocrit level (which is approximately 3...
cells), or macrocytic (large sized red blood cells). The hemoglobin is the typical test used forblood donation. A comparison with the hematocrit can be made by multiplying the hemoglobin by three. For example, if the hemoglobin is measured at 17, that compares with a hematocrit of .51.[...
Here, a simple and rapid point-of-care device is developed for the measurement of plasma free hemoglobin (PFHb) and hematocrit (Hct), based on colorimetry. The device consists of camera module, minimized centrifuge system, and the custom software that includes the motor control algorithm for ...
Hemoglobin variants with reduced oxygen affinity often go hand-in-hand with mild anemia due to a decreased erythropoietin response, and are characterized by an increased p50 value and decreased oxygen saturation. Many variants also exhibit minor instability and slightly elevated methemoglobin levels. Cli...
37 reported that a rapid decrease in 10% of hematocrit can raise the blood pressure of 8.6 mmHg and long-term hematocrit change can have the same tendency as acute change has. Hematocrit can affect blood pressure as it determines blood viscosity and regulates peripheral vascular resistance38. ...
