What is thrombocytosis? In thrombocytosis, the number of platelets is abnormally increased. Normally, their value in adults is between 150,000 and 400,000 per microliter (µl) of blood. If the measured value is higher, thrombocytosis is present. However, only platelet counts above 600,000 per microliter of blood are usually clinically relevant. Sometimes a value of more … Thrombocytosis: What it means
In thrombocytosis, the platelets in human blood are greatly increased for a short time and temporarily. Thrombocytosis occurs, for example, in response to blood loss or inflammation. Treatment is given on a case-by-case basis, depending on the cause, and may include, for example, the administration of ASA. What is thrombocytosis? The platelets in human blood … Thrombocytosis: Causes, Symptoms & Treatment
Blood platelet count too high If the platelets in the blood are elevated (>500. 000/μl), this is called thrombocytosis. These can be either primary (congenital, genetic) or secondary (acquired, caused by another disease). Secondary thrombocytosis is usually caused by infections, chronic inflammatory diseases, tissue injuries or certain forms of anaemia. Infections in which elevated platelet … Blood platelet count too high | Platelets
Therapy of platelet diseases A thrombocyte deficiency of less than 50,000 platelets per microlitre of blood is dangerous in most cases and should be treated. Depending on the cause of the deficiency, a number of treatment methods are available. In cases of pure platelet loss after heavy bleeding, for example after a traffic accident, platelet … Therapy of platelet diseases | Platelets
Platelet donation The donation of blood platelets (thrombocyte donation) is a procedure similar to plasma donation, in which 5 to 6 times more thrombocytes can be obtained than in a normal blood donation. In the donation process, only the platelets are removed from the donor’s blood via a “cell separator” and the remaining blood components … Platelet donation | Platelets
Introduction Blood platelets, or thrombocytes, are cells in the blood that play an important role in blood clotting, i.e. stopping bleeding. Along with red blood cells and immune cells (leukocytes), they are one of the main components of the blood. The technical term thrombocyte for blood platelets is derived from the Greek von thrombos for … Platelets
Definition Thrombocytes are blood platelets, of which each person carries approximately 150,000 to 350,000 per μl of blood. The thrombocytes perform an important function in blood clotting. Platelets therefore ensure that when a patient cuts himself or herself, the wound is closed again as quickly as possible and with as little blood loss as possible … Blood platelets (thrombocytes)
Platelet aggregation When a vessel is injured, the platelets come into contact with the connective tissue, which normally has no contact with the blood. A coagulation factor, the so-called von Willebrand factor (vWF), can now attach itself to this tissue from the blood. The thrombocyte has special receptors for this factor (vWR) and binds to … Platelet aggregation | Blood platelets (thrombocytes)
Blood count In the small blood count the number of thrombocytes is always determined because they have an important function in the coagulation cascade. The thrombocytes can be recognized here as small blood platelets without a cell nucleus. Compared to the white blood cells (leukocytes) and the red blood cells (erythrocytes) they look tiny and … Blood count | Blood platelets (thrombocytes)
Platelet donation In case of injuries or operations where large blood losses occur or in case of people who cannot produce enough platelets due to their disease(s), it may be necessary to administer platelets from other people, as they cannot be produced artificially. Nowadays this is done in the form of platelet concentrates. The donation … Platelet donation | Blood platelets (thrombocytes)
What are excessive platelets? There is a wide range of platelet counts that are safe or normal for humans. Healthy people have a platelet count between 150,000 and 450,000 platelets/μl blood. From a value of 450. 000 thrombocytes μl the platelet count is too high. In medical terms, a too high platelet count is referred … Platelets too high
Possible consequences The possible consequences depend on the cause of the excessive platelets. Even in a range that is too high, thrombocytes initially do not lead directly to consequences. However, the underlying disease can lead to various consequences. However, if the platelets are very high, which is not normally the case when thrombocytosis is secondary … Possible consequences | Platelets too high
