Abstract
The present invention relates to a method for measuring a biological value Vb in a liver wherein said method comprises the steps of: a/ applying an infrared radiation having at least a first wave number range between 2800 cm−1 and 3000 cm−1 to one or more portions, pi, of a sample of said liver, b/ detecting the intensity of the radiation after it has passed through each of one or more portions, p;, and generating a signal related to the detected intensity, c/ processing the generated signal(s) to calculate an average value va; d/ comparing said average value Va to a standard to obtain the biological value Vb.
Claims15
A method for measuring a biological value Vb in a liver wherein said method comprises the steps of:
- a/ applying an infrared radiation having at least a first wave number range between 2800 cm-1 and 3000 cm-1 to one or more portions, pi, of a sample of said liver,
- b/ detecting the intensity of the radiation after it has passed through each of one or more portions, pi, and generating a signal related to the detected intensity,
- c/ processing the generated signal(s) to calculate an average value Va;
- by:
- calculating, for each of the one or more portions, pi, a first value Vw1pi related to the first wave number range,
- or
- calculating the mean of the generated signal(s) for each portion pi to generate an average signal,
- calculating a first average value Vw1a related to the average signal at the first wave number range,
- and calculating an average value Va,
- and
- d/ comparing said average value Va to a standard to obtain the biological value Vb.
An apparatus for measuring a biological value Vb in a sample comprising:
- a site for submitting a sample to an infrared radiation,
- an infrared radiation source for providing a beam of infrared radiation having a wave number range between 1450 cm-1 and 3000 cm-1,
- a detector for detecting the intensities of the radiation at a first specific wave number range between 2800 cm-1 and 3000 cm-1 and at a second specific wave number range between 1450 cm-1 and 1710 cm-1 after it is passed through the sample and
- means for generating a signal related to the detected intensities.
