Final answer:
The histogram obtained from CDTM indicates that the patient has a higher quantity of CD8 T cells relative to another cell population, as the area under the peak for CD8 is three times greater.
Step-by-step explanation:
From the provided scenario, we can determine the relative quantity of CD8 T cells in the blood sample of an individual patient who is recovering from influenza. Using a flow cytometer and a fluorescent monoclonal antibody (mAb) specific to CD8, the sample yields two peaks in the histogram. Given that the area under the blue peak is three times greater than the red peak, it indicates a higher population of cells expressing CD8. Thus, the data suggests that the CD8 T cells are present in significantly higher quantities compared to another subset of cells detected by the flow cytometer, likely non-CD8 expressing cells.
