Answer
Based on the data in the table, allergic responses are typically indicated by an increased number of mast cells. In this case, Patient Z has a higher count of mast cells (1500 cells/mm³) compared to others. Therefore, I will assign allergic response to Patient Z.

Answer
For HIV, a lower count of lymphocytes can be indicative. Patient X has a significantly reduced count of lymphocytes at 2000 cells/mm³. Hence, I will assign HIV to Patient X.

Answer
An infected wound is often characterized by a higher count of phagocytes, as these are involved in fighting infections. Patient Y demonstrates a higher phagocyte count at 8000 cells/mm³ relative to the others. Thus, I will assign the infected wound to Patient Y.
