Live blood analysis (LBA), live cell analysis, Hemaview or nutritional blood analysis is the use of high-resolution dark field microscopy to observe live blood cells. Live blood analysis is promoted by some alternative medicine practitioners, who assert that it can diagnose a range of diseases. There is no scientific evidence that live blood ...
Dark-field microscopy produces an image with a dark background Operating principles of dark-field and phase-contrast microscopies Dark-field microscopy is a very simple yet effective technique and well suited for uses involving live and unstained biological samples, such as a smear from a tissue culture or individual, water-borne, single-celled ...
Dark-field X-ray microscopy (DFXM [1] or DFXRM [2]) is an imaging technique used for multiscale structural characterisation. It is capable of mapping deeply embedded structural elements with nm-resolution using synchrotron X-ray diffraction -based imaging.
These lesions can be healed without treatment within one to two months of exposure. The diagnosis can include dark-field or fluorescent microscopy of lesion; however, fifty percent of patients will be negative by nonspecific serology. If the infected individual does not treat the infection properly, the syphilis can progress to the secondary stage.

Blood smears showing various developmental stages of the malaria parasite Plasmodium falciparum, stained with Wright stain and Giemsa stain. The preferred and most reliable diagnosis of malaria is microscopic examination of blood smears, because each of the four major parasite species has distinguishing characteristics.
Bright-field microscopy (BF) is the simplest of all the optical microscopy illumination techniques. Sample illumination is transmitted (i.e., illuminated from below and observed from above) white light , and contrast in the sample is caused by attenuation of the transmitted light in dense areas of the sample.
Setting up weak-beam dark-field imaging in transmission electron microscopy involves several steps, which may vary depending on the specific TEM instrument and the sample being analyzed. This may require further optimization and adjustment to achieve the desired image quality and contrast.
