Which condition is indicated by decreased PLTs?

  1. Thrombocytosis

  2. Leukopenia

  3. Thrombocytopenia

  4. Leukocytosis

The correct answer is: Thrombocytopenia

Thrombocytopenia is indicated by decreased platelets (PLTs). Platelets are essential for blood clotting, and a decrease in platelet count can lead to an increased risk of bleeding and difficulty in forming clots to stop bleeding. Thrombocytosis refers to an elevated platelet count; leukopenia is a decrease in white blood cells; and leukocytosis is an increase in white blood cells. However, only thrombocytopenia specifically relates to a decrease in platelets, making it the correct answer in this case.
