The Platelet count test is the measurement of number of platelets a person has, on average, per microliter and the test gives a platelet count per microliter (mcL) of blood. Generally Platelet count test includes in CBC test.
The ideal platelet range is 150,000 to 400,000 per mcL in most healthy people.
High platelet count is called as thrombocytosis. Low platelet count is called as thrombocytopenia.
A doctor will order a platelet count test if they suspect a person has a disorder that affects platelet count.
When platelet count is high and for some reason the bone marrow is creating too many platelets, it is called primary, or essential, thrombocytosis. When excess platelets are due to an infection or other condition it is called secondary thrombocytosis.
Having high platelet count increase the risk of blood clots, a person can blood clots more easily when they have too many platelets
Some common reasons that platelets are temporarily got high include:
More serious and chronic conditions
If a person’s platelet count remains high, there may be other conditions which can be responsible such as:
A low platelet count can create problem for the blood to clot, putting a person at risk of excessive bleeding.
Higher risk of spontaneous bleeding
A person can begin bleeding spontaneously if the blood platelet count falls below 20,000 per mcL, those people may require a blood transfusion
A platelet test is a very safe, common test. All tests carry some risk, however, these may include:
Changes in platelet count may mean that a person has a chronic illness or that there is an issue with the bone marrow. There are various other factors which can affect the results. Talk to your doctor to know the actual issue
