Final answer:
A platelet histogram is created on a Coulter counter by using the forward-scatter and side-scatter detectors to collect data from the platelets. This process is used to analyze platelet populations and identify any abnormalities or variations.
Step-by-step explanation:
A platelet histogram is created on a Coulter counter by using the forward-scatter and side-scatter detectors to collect data from the platelets.
The forward scatter represents the number of platelets, while the side scatter represents the fluorescence of each platelet.
These data are then plotted on a histogram, with the forward scatter on the y-axis and the side scatter on the x-axis, to visualize the distribution of platelets based on their characteristics.
This process is used to analyze platelet populations and identify any abnormalities or variations in size or granularity.
