Darkfield Microscope Exam for Spirochetes

Alaska rates for HCPCS 87166

Examination of fluid or scrapings under a microscope arranged so that light strikes the sample from the side, making extremely thin corkscrew-shaped bacteria stand out bright against a dark background. It is used mainly to look for the organism that causes syphilis in fluid taken from a sore, and it can give an answer straight away.
