Abstract:
1. A method for noninvasive analysis of at least one blood component in venous blood comprising the steps of: placing a probe in contact with a surface of a tissue directly under a big vein associated with an underside of a patient's tongue, where the probe includes a tip having a radiation outlet and a response inlet so that both the radiation outlet and the response inlet are simultaneously in contact with the surface and where the outlet is connected to a light source via a light source conduit and the inlet is connected to a detector via a response conduit; irradiating venous blood in the big vein with radiation having at least one frequency or wavelength; detecting a response from the venous blood irradiated in the irradiating step; and calculating a concentration of a blood component, a value of a blood parameter or a mixture or combination thereof in the venous blood from the response.
