Method for diagnosing malignancy diseases

摘要

The method for diagnosing malignancy diseases involving analysis of blood plasma by laser correlational spectroscopy (LSC) techniques includes the steps of: preparing a weak diluted solution of native blood plasma, determining a spectral density of light scattering intensity fluctuations within the frequency range between 1 and 1000 Hz, distinguishing a spectrum core and making a diagnosis from a frequency of a maximum and an intensity-to-half-width ratio of a spectrum core envelope, a malignancy disease being detected when the diagnostic parameters are less than the appropriate rates. The apparatus for diagnosing malignancy diseases includes a nephelometer and a series-connected correlation spectrum analyzer. The nephelometer further includes a second scattered light detector disposed symmetrically about a first scattered light detector, a signal multiplier whose inputs are coupled to outputs of the first and second scattered light detectors, a low pass filter whose input is coupled to an output of the signal multiplier, and an output is coupled to a correlator of the spectrum analyzer, a conventional ampoule for a solvent being used as a measuring cuvette in the nephelometer.
