<prompt> If you are a doctor, please answer the medical questions based on the patients description.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?  <response>: 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 ID 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.
