Thrombozytenzahlen

Thrombozytenzahlen, also known as platelet counts, refer to the number of platelets circulating in a person's blood. Platelets are tiny, irregular-shaped cell fragments produced in the bone marrow that play a crucial role in hemostasis, the process of stopping bleeding. When a blood vessel is injured, platelets aggregate at the site of damage and form a plug, which is then reinforced by fibrin to prevent excessive blood loss.

A normal platelet count typically ranges from 150,000 to 450,000 platelets per microliter of blood. Deviations from this range can indicate underlying health issues. A low platelet count, known as thrombocytopenia, can result from various causes, including autoimmune disorders, infections, certain medications, or bone marrow problems. Symptoms of thrombocytopenia can include easy bruising, prolonged bleeding from cuts, nosebleeds, and bleeding gums. In severe cases, it can lead to life-threatening internal bleeding.

Conversely, a high platelet count, called thrombocytosis or thrombocythemia, can be either reactive or essential. Reactive thrombocytosis often occurs in response to inflammation, infection, or iron deficiency. Essential thrombocythemia is a rare myeloproliferative disorder where the bone marrow produces too many platelets. Elevated platelet counts can increase the risk of blood clots forming in arteries or veins, potentially leading to stroke, heart attack, or deep vein thrombosis.

Determining thrombozytenzahlen is a standard part of a complete blood count (CBC) test, which is frequently performed during routine medical check-ups or when investigating symptoms suggestive of bleeding or clotting disorders. The interpretation of platelet counts should always be done in conjunction with other clinical findings and laboratory results by a qualified healthcare professional.
