Final answer:
The correct formula to figure out the absolute leukocyte count is Absolute Count = (% of WBC type * Total WBC count) / 100, which calculates the number of specific WBCs in blood. This method assists in medical diagnosis by indicating potential infections or diseases.
Step-by-step explanation:
To figure out the absolute leukocyte count, one must multiply the percentage of a specific type of white blood cell (WBC) by the total WBC count, and then divide by 100. Therefore, the correct formula is:
Absolute Count = (% of WBC type * Total WBC count) / 100
This calculation provides the number of a specific type of leukocyte present in a given volume of blood. The percentage of each WBC type is determined by counting and classifying the cells in a systematic manner, which often involves scanning a blood smear and using a pattern that prevents double-counting. After classifying at least 50 to 100 cells, the observer can calculate the proportion of each cell type. These values are important for medical diagnostics as they can indicate the presence of infections or diseases by showing deviations from normal leukocyte ranges.
