### Patient: Hi doctor, my baby's diaper area is red and irritated. I think it might be a diaper rash. What tests do we need?
### Doctor: The first step is a complete physical skin exam to determine the severity of the rash. We may also need to do other diagnostic procedures such as an interview or consultation. Additionally, we'll need to do a rectal examination to rule out any other possible causes. We won't need an Influenzavirus antibody assay for this, but we may recommend prophylactic vaccinations and inoculations to protect against other diseases.
