What does platelet count mean?
Platelet count is a blood test that measures the amount of platelets present in the body. Platelets are blood cells responsible for blood coagulation, ie they help to stop bleeding in the event of injuries or injuries.
Why is platelet counting?
Platelet count is important to evaluate the body’s ability to properly coag the blood. When platelet count is low, there may be a higher risk of bleeding, while when it is high, it may indicate a risk of clot formation.
How is platelet count?
Platelet count is performed through a blood test called complete blood count. In this exam, it is possible to check the amount of platelets present in the blood, as well as other important information about the blood cells.
Normally, platelet count is expressed in number of platelets per microlyiter of blood. Reference values may vary according to the laboratory, but are usually between 150,000 and 450,000 platelet platelets.
What can cause changes in platelet count?
There are several conditions that can cause changes in platelet count. Some examples include:
- thrombocytopenia: When platelet count is below normal. It can be caused by autoimmune diseases, infections, medications, among other factors.
- Thrombocytosis: When platelet count is above normal. May be caused by inflammation, infections, anemia, among other factors.
- Bone Marrow Diseases: How leukemia or myelophybrosis, which can affect platelet production.
- Use of medicines: Some medications may affect the production or function of platelets.
What are the symptoms of platelet count changes?
Symptoms of platelet count changes may vary according to the cause and severity of the problem. Some common symptoms include:
- Spontaneous bleeding such as nasal bleeding, gingivorragia (gum bleeding), bruises or purple spots on the skin;

- Prolonged bleeding after cuts or injuries.
