Hematocrit
Hematocrit is a measure of the proportion of red blood cells (erythrocytes) in the blood, expressed as a percentage. It is an essential parameter evaluated in a complete blood count (CBC) test and helps in determining various conditions related to the blood, such as anemia, polycythemia, and dehydration.\n\nHematocrit is determined by the ratio of the volume of red blood cells to the total volume of blood, which includes red blood cells, white blood cells, platelets, and plasma. Normal hematocrit values vary depending on age and gender. In general, the average normal hematocrit range is:\n\n- For adult men: 40% to 54%\n- For adult women: 36% to 48%\n- For children: 35% to 49% (ranges vary depending on age)\n\nLow hematocrit values may indicate anemia, blood loss, vitamin or mineral deficiencies, or bone marrow dysfunction. In contrast, high hematocrit values may suggest polycythemia (an increase in red blood cell production), dehydration, or other medical conditions that may cause an increased red blood cell volume.\n\nIt is essential to interpret hematocrit values in conjunction with other blood tests and patient clinical history to diagnose and manage blood-related conditions accurately.
