Platelet Numbers is spelled using the International Phonetic Alphabet as [ˈpleɪtlɪt ˈnʌmbərz]. The word begins with the vowel sound 'ay' as in 'play', followed by the consonant cluster 't-l' pronounced as a syllabic 'l'. The second syllable features the short 'u' sound as in 'cup'. The final syllable has the stressed vowel 'er' as in 'her' and the 'z' sound as in 'buzz'. This phrase pertains to the quantity of platelets found in a person's blood, often used in medical settings for diagnostics and treatment decisions.
Platelet numbers refer to the quantity of platelets, also known as thrombocytes, found in the blood of an individual. Platelets are small, disc-shaped blood cells that play a crucial role in the clotting process, helping to stop bleeding by forming blood clots.
The normal platelet count in a healthy person usually ranges from 150,000 to 450,000 platelets per microliter of blood. This count can vary slightly depending on the laboratory or healthcare facility conducting the analysis, as methods and reference ranges may differ.
Evaluation of platelet numbers is typically performed through a blood test called a complete blood count (CBC). In this test, a sample of blood is analyzed to determine the number of platelets present. Platelet numbers are measured and reported as part of the CBC, along with other blood cell counts such as red and white blood cells.
Abnormal platelet numbers can indicate various health conditions. A low platelet count (thrombocytopenia) may result from factors such as viral infections, autoimmune disorders, certain medications, or bone marrow disorders. Conversely, a high platelet count (thrombocytosis) can be caused by inflammation, infection, recent surgery, iron deficiency, or other underlying health issues.
Regular monitoring of platelet numbers is crucial for diagnosing and managing blood disorders, as well as for assessing the risks associated with clotting or bleeding. Healthcare professionals use platelet numbers as an important parameter in evaluating overall health and determining appropriate treatment options for patients.
The word "platelet" is derived from the French word "plaque" meaning "plate" and the suffix "-let", indicating something small. It was first used in the 19th century to describe the small blood cells involved in clotting.
The word "numbers" is derived from the Latin word "numerus" meaning "number" or "count". In the context of "platelet numbers", it refers to the count or quantity of platelets in the blood.
Therefore, the etymology of the term "platelet numbers" is a combination of the French word "platelet" and the Latin word "numbers", referring to the count or quantity of the small blood cells involved in clotting.
