The spelling of the word "Platelet Number" can be explained using the International Phonetic Alphabet (IPA). The first syllable "plāt" is pronounced as /pleɪt/, with a long 'a' sound followed by the 't' sound. The second syllable "let" is pronounced as /lɛt/, with a short 'e' sound followed by the 't' sound. The final syllable "numb-er" is pronounced as /ˈnʌm.bər/, with stress on the first syllable and a schwa sound in the second syllable. Overall, the word "Platelet Number" is pronounced as /ˈpleɪt.lɛt ˈnʌm.bər/.
Platelet Number refers to the quantitative count of platelets in the blood. Platelets, also known as thrombocytes, are small, irregularly-shaped fragments of cells that circulate in the bloodstream. They are essential components of the blood clotting process, which helps to control bleeding and promote wound healing.
The platelet number is measured to assess the adequacy of a person's platelet production and function. This count is typically determined through a blood test known as a complete blood count (CBC) or a platelet count. During this test, a small sample of blood is collected and analyzed to determine the number of platelets present.
The normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Deviations from this range can indicate certain medical conditions or diseases. If the platelet count is too low (thrombocytopenia), it may result in excessive bleeding or difficulty in clot formation. Conversely, an abnormally high platelet count (thrombocytosis) can increase the risk of abnormal blood clotting.
Platelet number is crucial in assessing various hematological disorders, such as immune thrombocytopenia, leukemia, bone marrow disorders, or as a side effect of certain medications. Monitoring platelet number is also essential during surgeries or when prescribing anticoagulant medications.
In summary, platelet number refers to the quantitative measurement of platelets in the blood, indicating their level in the body and helping to diagnose and monitor various bleeding and clotting disorders.
The word "platelet" originated from the French word "plaque" meaning "plate" and the suffix "-let" denoting "small" or "diminutive". In the context of biology, platelets are small, disk-shaped blood cells that play a crucial role in blood clotting.
The term "platelet number" is formed by combining "platelet" with "number". The word "number" originated from the Latin word "numerus", which means "count" or "quantity". Therefore, "platelet number" refers to the count or quantity of platelets present in the blood.
