Final answer:
The percentage of leukocytes in the blood smear of a healthy adult can vary depending on the individual, but a normal range is typically between 0.4% and 1.1% of the total volume of blood cells.
Step-by-step explanation:
The percentage of leukocytes in the blood smear of a healthy adult can vary depending on the individual. However, a normal range for white blood cells is typically between 4,000 and 11,000 cells per microliter of blood. This represents approximately 0.4% to 1.1% of the total volume of blood cells.
It's important to note that the percentage of leukocytes can be influenced by factors such as age, gender, and overall health. Additionally, different types of leukocytes, such as neutrophils, lymphocytes, monocytes, eosinophils, and basophils, can have varying percentages within the total leukocyte count.
Therefore, in order to determine the exact percentage of leukocytes in a specific blood sample, a complete blood count (CBC) test is typically performed by a medical professional.
