What happens if my CBC test shows low platelets?

A low platelet count, also known as thrombocytopenia, can increase your risk of excessive bleeding and bruising. This condition can be caused by a variety of factors, including viral infections (such as dengue or HIV), autoimmune diseases like lupus, or bone marrow disorders such as leukemia. Certain medications, like chemotherapy or blood thinners, can also reduce platelet counts. If your CBC results show low platelets, your doctor may recommend further tests to identify the underlying cause and provide treatment to prevent complications, such as platelet transfusions in severe cases.
