Three to Five days is usually expected lab time. Ten days and ya need to think. How many days does the lab need to verify that they will be reimbursed for the work. And how long does the Dermatologist have to wait before the insurance company will allow him to bill for another visit.
Having worked around a Histo Lab in the 70's the diagnosis is really easy. Back in the day you ran a slice, stained it, then took a glance under the microscope. After ya did that ya called over the Pathologist and they took a second look and signed off. Certainly it must be even easier now days.
I am a Melanoma survivor. Every time the Derm guy lops off some little gumba I cringe. Now comes the wait... RATS!
