A low hematocrit of 0.005 may be the result of a decrease in red blood cell count due to anemia, or it may be a relative decrease due to an increase in circulating blood volume.
Erythrocyte specific volume refers to the total volume of red blood cells in the peripheral blood as a proportion of the circulating blood volume. Patients with various causes of anemia such as hemolytic anemia, iron-deficiency anemia, megaloblastic anemia, and anemia of chronic disease have a decreased red blood cell count, which results in a decrease in total red blood cell volume, leading to a decreased hematocrit.
The increase in circulating blood volume during pregnancy can lead to a relative decrease in hematocrit, which can return to normal by itself after the end of pregnancy and does not require special treatment.
Patients with low hematocrit due to decreased red blood cell counts need to go to the hematology department in time to complete the relevant examinations to determine the cause of the anemia, and then treat the cause of the anemia and actively correct it.
