Platelet hematocrit is high. What does this mean?

It is the increase of MPV, indicating that megakaryocytes are highly mature and bone marrow has good platelet production. The increase of PLT, that is, the increase of total platelet count, is generally within 450 units, which is acceptable. Generally, it is infection, blood loss, hemolysis and tumor. Will increase platelets.

Platelets are small pieces of cytoplasm released from the cytoplasm of mature megakaryocytes in bone marrow. Although megakaryocytes are the least hematopoietic cells in bone marrow, accounting for only 0.05% of the total number of nucleated cells in bone marrow, platelets produced by megakaryocytes are extremely important for the hemostasis function of the body.

Matters needing attention in hematocrit:

1, the platelet count can vary by 6%-1 0% at different times in1day, which is lower in the morning and slightly higher in the afternoon; It is lower in spring and slightly higher in winter.

2. The population in the plain area is small, and the population in the plateau area is large; High during exercise and recovery after rest; It decreases before menstruation and increases after menstruation.

3. Venous blood is higher than finger blood.

4. Because there are many factors that affect platelet count, it is difficult to get accurate results in one test. You have to count it several times before you can determine whether there is any change.
