Oligoscan (also called cell check or Zell Check) is the name of a pseudo-medical device of the Luxembourg manufacturer Luxometrix. Important trading partner is the French company Physioquanta. According to Oligoscan information, it is possible to measure the so-called "mineral status" of a customer / patient and his/her exposure to heavy metals. These measurements are completed in a very short time (20 seconds), and no blood test or any other invasive test is required. In Germany, the device is also marketed as a Zell Check.
In reality, the device has been developed for the printing industry. It is a colorimeter of the company X-Rite (model i1Photo pro2). The cooperation between Lucometrix and X-Rite has not been made public by either company. There is no evidence of the suitability of the device for the specified medical purpose. In the German-language advertising for Oligoscan, a note is published, specifically for customers: "Note: The Oligoscan® analysis can / must not be used for medical diagnosis."
CEO of the company Physioquanta is Guillaume Moreau (born 1972). As early as March 2010, Physioquanta was banned in France from promoting its pseudo-medical devices (including Physiodétox, Physioscan (see Physiospect), Physioalcali, Quantarelax, Quantapulse), because the claimed efficacy for medical use is lacking for these devices.
Because there is no evidence that Oligoscan tests represent a recognized procedure, the tests cannot be billed as “lab exams”. The customer / patient must pay the bill him/herself and health insurances do not cover the costs. Customers have to provide their name and other personal information for each Oligoscan measurement, and this information is provided via internet to a remote server. How data protection is guaranteed, remains unclear.
principle of photometry
In general, a photometer is an instrument that measures light intensity or the optical properties of solutions or surfaces. A monochromatic light source radiates through the sample. Part of the light is absorbed by the analyte and a detector allows the determination of the analyte’s concentration in the sample. (Source: Wikipedia) According to the National Physical Laboratory, “Photometry is the measurement of electromagnetic radiation weighted by the human eye's response. This response changes with wavelength” “In photometry, the word 'luminous' is used to indicate that measurements have been made using a detection system (called a photometer) that has a spectral response similar to that of a human eye. The two principal photometric scales maintained at NPL are of luminous intensity and luminous flux. Setting up appropriate geometries permits calibrations of other quantities, such as luminance from luminous intensity standards. NPL has extensive facilities available for the photometric measurement of both sources and detectors, including photometers, luxmeters, luminance meters and colour temperature meters.”
The British National Physical Laboratory provide training courses in photometric techniques and offer their expertise in consultancy services. www.npl.co.uk/principles-of-photometry
Oligoscan buyers and users are only trained in how the device is placed on the hand and in utilizing the provided software. All this takes little time, less than an hour.
principle of spectroscopy
Spectroscopy is the study of the interaction of electromagnetic radiation in all its forms with matter. In Optical Emission Spectroscopy (OES) the sample to be tested for metal and trace elements is vaporized. Atoms and ions contained in the atomic vapor are excited into emission of radiation. The radiation is passed to the spectrometer optics where it is dispersed into its spectral components. From the range of wavelengths emitted by each element (or metal), measurements take place. The radiation intensity, which is proportional to the concentration of the element (or metal) is recalculated, based on calibration curves and is shown as percent concentration.
