Darkfield Microscopy


Darkfield microscopy is a method of analyzing blood from a patient in great detail to glean information about the terrain, the immune system, nutritional status, and oxidation reduction reactions. A darkfield microscope gives a very different image than conventional light field microscopy.

Patients at the Marsden Centre of Naturopathic Excellence receiving a darkfield assessment will be able to see evidence in the blood of terrain changes, nutritional status and the form of the various blood symbionts. There are many individuals who claim to be darkfield technicians, but whose training and ethics are questionable. At MCNE all darkfield slides are viewed by highly experienced and trained Naturopathic Doctors.

More Information on Darkfield Microscopes


The darkfield microscope is unique because of its special optics and light condenser. In figure 1 there is a schematic of a darkfield microscope which shows how the light from the source is redirected by mirrors so that it shines obliquely on the specimen. This is what gives the dark image of shadows seen through the eyepiece. Light field microscopy requires staining of the sample before viewing in order to visualize the slide. This causes cell death. Darkfield microscopy however can provide physicians with live cells for viewing which has significant assessment applications.

The darkfield microscope is considered an experimental device valid for research purposes only. MCNE makes no claims of diagnosis or treatment with this device.
