What is the normal platelet count in children?

Children are the treasures of every family, so the health of each child concerns the whole family. A healthy, lively and cute baby is what every parent wants, so the baby's health becomes a crucial concern. In daily life, the baby's health is always the most important concern of parents. Let me tell you about the normal platelet values ​​in children.

Platelets

platelet), referred to as PLT. It is one of the formed elements in mammalian blood and is a small piece of cytoplasm with biological activity that falls off from the cytoplasm of mature megakaryocytes in the bone marrow. They are small in size, without nucleus, and are in the shape of a slightly convex disc on both sides, with a population of (100~300)×10^9 per L and a diameter of 2-3 microns. Platelets have long been viewed as non-functional cell fragments in the blood. Platelets have a specific morphological structure and biochemical composition. Their number in normal blood is relatively constant (for example, the human platelet count is 100,000 to 300,000 per cubic millimeter). They play an important role in physiological and pathological processes such as hemostasis, wound healing, inflammatory response, thrombosis, and organ transplant rejection. Platelets are only found in mammalian blood. There is no nuclear structure, that is, no chromosomes.

Function

Platelets are small pieces of cytoplasm that fall off from megakaryocytes in the bone marrow, so they have no nucleus and have a complete cell membrane on the surface. Platelets are small in size, with a diameter of 2 to 4 microns, and are biconvex disc-shaped. They are easily affected by mechanical and chemical stimulation, at which time they extend protrusions and become irregular in shape. Under an electron microscope, the surface of the platelet membrane is coated with sugar, which can adsorb plasma proteins and coagulation factors. Platelets play an important role in the bleeding and coagulation process.

The reference range of platelets in children is 100-300. The platelet count in newborns is low and reaches the adult level after 3 months.

Platelets are very important to the body. All elements in the human body have a normal value, which is the value that keeps our body in a normal balance. Once this value is not within the normal level, it means that there is something wrong with our body, which requires us to pay more attention. It’s best to go to the hospital for a check-up.
