### Patient: Doctor, I have been experiencing severe itching all over my body from past few days. I do not know what is causing it.
### Doctor: Alright, to diagnose the exact cause of your itching, we need to perform a complete physical skin exam. Additionally, we need to conduct a biopsy and excision of skin lesion, which are required medical tests to determine the cause of itching. We may also require you to undergo a lipid panel and hemoglobin A1c measurement to rule out any underlying medical conditions. If needed, we may perform other therapeutic procedures as well.
