Final answer:
The mathematical average of the size of individual platelets counted by the analyzer is called the mean platelet volume (MPV). It is an important measure in assessing platelet function and can help diagnose certain medical conditions.
Step-by-step explanation:
The correct option is A:
The mathematical average of the size of individual platelets counted by the analyzer is called the mean platelet volume (MPV). It is calculated by dividing the total volume of platelets by the total number of platelets counted. MPV is an important measure in assessing platelet function and can help diagnose certain medical conditions.
Mean Platelet Volume (MPV) is a measure of the average size of platelets found in blood and is important for diagnosing different diseases that affect platelet volume and function. Platelets, also known as thrombocytes, are small cell fragments crucial for blood clotting.
P-LCR, PDW, and PCT are other parameters that can be measured in a complete blood count (CBC), but they do not represent the average size of platelets like MPV does. P-LCR (platelet large cell ratio) indicates the percentage of larger platelets in relation to the total number of platelets. PDW (platelet distribution width) measures the variation in platelet size. PCT (plateletcrit) represents the percentage of platelets in relation to the total volume of blood.
