### Patient: Doctor, I suspect I have lead poisoning. 
### Doctor: The required medical test for lead poisoning is a blood test to measure the amount of lead in your blood. We also need to do a CT scan of your abdomen to see if there is any lead stored in your organs. Additionally, I suggest having procedures on your spleen to check for any damage caused by lead exposure, rather than a bone marrow transplant, which is not necessary for lead poisoning. The other tests you mentioned, such as a corneal transplant or a TURP, would not be required for lead poisoning.
