### Patient: Doctor, I have been experiencing extreme itching on my scalp and noticed some small insects moving around. I think I have lice. What medical tests do I need to undergo?
### Doctor: A complete physical skin exam needs to be performed on your scalp to confirm the presence of lice. Also, a culture wound will be taken to determine the exact type of lice infestation. If necessary, an incision and drainage (I&D) procedure could be done. Excision of skin lesions also helps in assessing the severity of infestation which altogether helps in determining the urgency of the treatment.
