High hematocrit

summary

Last week was the company's routine annual physical examination, in which my blood physical examination report showed that my hematocrit value was too high, the value was 375, and the doctor also asked me to pay attention. So, what's the matter with the high hematocrit?

High hematocrit

First, the increase of hematocrit indicates that the megakaryocytes are highly mature and the bone marrow has good platelet production. LT rise, that is, the increase in the total number of platelets, the general test within 450 units, acceptable, general infection, blood loss, hemolysis, tumor will make platelets rise.

Second, vasoconstriction can also cause the increase of PCT, which is because platelets adhere to the vascular endothelium. When the blood vessels are damaged and contracted, the glycoprotein on the surface of platelets adheres to the collagen substance under the endothelium, and platelets aggregate with each other, so that platelets accumulate and the natural hematocrit will also increase.

Third: thrombocytosis is the proportion of platelets, which is meaningless. High platelets may lead to thrombosis and increased blood viscosity. If you are too worried, you should monitor at any time and pay close attention to all aspects of your child.

Fourth: hematocrit is a calculated value, which is the result of the average volume of platelets multiplied by the number of platelets. If the number of platelets is normal, then the increase of hematocrit indicates that there are more large platelets. Hematocrit is the proportion of platelets in the blood, only this item beyond the reference value is meaningless, do not care.

Fifth: if the platelet is slightly higher than the normal value, if other values are normal and no symptoms, there will be no problem. It can be observed temporarily; if the pure platelet is very high and the test error factor is excluded, it is necessary to determine whether it is secondary or primary, that is, whether there is the cause of thrombocytosis, such as infection, tumor, iron deficiency, etc,

Sixth: the common causes of thrombocytopenia are physiological, such as blood concentration, after strenuous exercise, slightly higher in the afternoon, increased after menstruation, and pathological, such as acute infection, acute hemolysis, polycythemia, primary thrombocytopenia, and some tumor patients.

matters needing attention

Simple high platelet has no clinical significance. If there are no other symptoms, there is no need to check the treatment. Because of the great individual difference, the treatment is carried out after observation.
