In dark-field illumination special optics are used in which incoming light rays bypass the lens. Only when a preparation is brought into the path of the rays does the light, bent by the preparation, reach the lens and contribute to the image. The structures appear illuminated against a dark background. In this diagnostic process a blood is taken from a drop of blood from the ear and viewed under the dark-field microscope.
In the examination in addition to evaluating the acid base ratio, verification of differentiation of symbiotes is of particular importance. Symbiotes are the smallest life forms that get into the blood through the food we eat, and which are found in all bodily fluids. According to Professor Enderlein these symbiotes can develop abnormally and are an indication of how healthy a person is. Good diagnosticians believe with this microscope that they are able to determine the quality of the blood platelets (thrombocytes) and the white blood cells (leucocytes). In addition, the consistency and the bioaccumulation level of the blood, allergic and inflammatory reactions, a secondary oxygen deficiency etc. are also determined.
Many doctors are happy to equate dark-field microscopy with charlatanism, and I must say with good reason. Not because it is not a sufficiently meaningful technology, but because many hobby diagnosticians who have been to a one-day course in dark-field microscopy believe that they can make the most precise diagnoses with it. I have encountered this phenomenon many times and I also protect myself from this type of diagnosis. That being said, I have become acquainted with many practitioners who have been using dark-field microscopy daily for many years, and who are quite capable of using it draw exact conclusions.
