- Platelet: An irregular, disc-shaped element in the blood that assists in blood clotting. During normal blood clotting, the platelets clump together (aggregate). Although platelets are often classed as blood cells, they are actually fragments of large bone marrow cells called megakaryocytes. Search MedTerms:

How to Increase a Low Platelet Count A low platelet count, medically known as thrombocytopenia, is a health disorder in which your blood has a lower than normal number of platelets. Platelets are the smallest of the blood cells that aid in blood clotting by forming plugs in blood vessel holes.The platelets circulate in the blood with an average lifespan of 5 to 9 days. A normal platelet count in a healthy person ranges from 150,000 to 450,000 platelets per microlitre of blood.latelets are the smallest of the blood cells that aid in blood clotting by forming plugs in blood vessel holes.

What is the medical term meaning giant multinucleate cell from which fragments to form platelets? Platelets (aka thrombocytes) are small cell fragments that are involved in hemostasis (a complex process which causes the bleeding process to stop) leading to the formaton of … blood clots. Thrombocytopenia refers to the bleeding disorder caused by platelet deficiency or dysfunction.

Normal Platelet Count Platelets are minute cells that circulate in the blood of mammals, and play an important role in clotting. This write-up provides a brief overview about the normal platelet count in humans. Advertisement. Platelets are formed by fragmentation of bone marrow cells called megakaryocytes.

What are Platelets and Why are They Important? A normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis; having less than 150,000 is known as thrombocytopenia. You get your platelet number from a routine blood test called a complete blood count (CBC). normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood.

Thrombocytopenia (Low Platelet Count) Platelets are important elements in the blood that are important for blood coagulation (clotting and prevention of bleeding). The normal platelet count ranges between 150,000 and 450,000 per microliter (one-millionth of a liter).Although the number of platelets is decreased, their function may remain intact in most cases of thrombocytopenia. All blood cells (white cells, red cells, and platelets) are made in the bone marrow.hrombocyte is the medical term for platelet. Thrombocytopenia means a lower platelet count in the blood compared to the normal range.

What Are Platelets? Platelets are made in your bone marrow along with your white and red blood cells. Your bone marrow is the spongy center inside your bones. Another name for platelets is thrombocytes, and health care providers usually call a clot a thrombus.our health care provider may do a blood test called a complete blood count to find out if your bone marrow is making the right number of platelets: A normal platelet count is 150,000 to 450,000 platelets per microliter of blood. Risk for bleeding develops if a platelet count falls below 10,000 to 20,000.

- 78 Followers. A. Platelets are the tiny blood cells that help stop bleeding by binding together to form a clump or plug at sites of injury inside blood vessels. A normal platelet count is between 150,000 and 450,000 platelets per microliter (one-millionth of a liter, abbreviated mcL).The average platelet count is 237,000 per mcL in men and 266,000 per mcL in women. platelet count below 150,000 per mcL is called thrombocytopenia, while a platelet count over 450,000 is called thrombocytosis. Platelets seem to have a large backup capacity: blood typically still clots normally as long as the platelet count is above 50,000 per mcL (assuming no other problems are present).

- true STANDARD HEMATOLOGY: Platelets, or thrombocytes, are small, colorless, enucleated bodies. They are produced in the bone marrow by fragmentation of megakaryocytes. Megakar…yocytes are large cells found in bone marrow that produce platelets by fragmenting their cytoplasm.

Complete Blood Count (CBC) Medical Definition of Platelet count. Platelet count: The calculated number of platelets in a volume of blood, usually expressed as platelets per cubic millimeter (cmm) of whole blood. Platelets are the smallest cell-like structures in the blood and are important for blood clotting and plugging damaged blood vessels.

CONNECTIVE TISSUE - BLOOD & BLOOD FORMING TISSUES Platelets are fragments of cytoplasm detached from Megakaryocytes in the bone marrow. They aggregate together during the process of blood coagulation and clotting. Platelets are small (2-5 um), have no nucleus and are ovoid shaped.

Platelet Count The platelet count is a test that determines the number of platelets in a person's sample of blood. When there is an injury to a blood vessel or tissue and bleeding begins, platelets help stop bleeding in three ways. They: 1  Adhere to the injury site. 2  Clump together (aggregate) with other platelets.n excess of platelets can cause excessive clotting or sometimes bleeding if the platelets are not functioning properly. However, people with too many platelets often have no signs or symptoms, so the condition may be found only when a platelet count is done as part of a health check or for other reasons.

Platelet Count A platelet count is used to detect the number of platelets in the blood. The test is included in a complete blood count (CBC) , a panel of tests often performed as part of a general health examination. Platelets are tiny fragments of cells that are essential for normal blood clotting. platelet count may be performed in conjunction with one or more platelet function tests, which assess the function of platelets, and other tests that evaluate coagulation such as PT and PTT. If results are not within the normal interval, a number of other tests may be performed to help give clues as to the cause.

What Are Platelets? What Are Platelets? Platelets are tiny blood cells that help your body form clots to stop bleeding. If one of your blood vessels gets damaged, it sends out signals that are picked up by platelets. The platelets then rush to the site of damage and form a plug, or clot, to repair the damage.

Those with a low platelet count benefit from a healthy diet How 1823 app has made complaining to Hong Kong government easier. Thrombocytes or platelets are colourless blood cells that assist in blood clotting by forming plugs in blood vessel holes. A healthy person has between 150,000 to 400,000 platelets per microlitre of blood. However, chemotherapy, radiotherapy, dengue fever, chronic hepatitis, viral infection or imbalances in the immune system can cause a sub-normal platelet count.
