Final answer:
The evidence that suggests an impact on the immune system includes decreased white blood cell count, elevated C-reactive protein, antibody deficiency, and increased platelet count.
Step-by-step explanation:
The evidence that suggests an impact on his immune system includes:
- Decreased white blood cell count: Fewer white blood cells may result in a compromised immune system.
- Elevated C-reactive protein: High levels of C-reactive protein indicate inflammation, which can be a sign of an immune system response.
- Antibody deficiency: Antibodies are an important part of the immune system, so a deficiency can weaken the immune response.
- Increased platelet count: While platelets are not directly related to the immune system, their increase in count can be a result of an immune system response to infection or inflammation.
