Final answer:
The correct answer is serum protein quantification. A blood smear is primarily used for visualizing cellular morphology, estimating blood cell numbers, and identifying hematogenous infectious agents.
Step-by-step explanation:
The correct answer is b. Serum protein quantification. Serum protein quantification cannot be completed on a properly prepared blood smear, as it requires a different testing method. A blood smear is primarily used for visualizing cellular morphology, estimating blood cell numbers, and identifying hematogenous infectious agents.
For example, with a properly prepared blood smear, you can use a microscope to observe and analyze the shapes and sizes of different blood cells to determine their characteristics. You can also count the number of red blood cells, white blood cells, and platelets to estimate their quantities in the blood sample. Additionally, you can identify any infectious agents present in the blood, such as bacteria or parasites.
