Patent ID: 8552383

Claim:
A method for in-vitro determination of origin of biological cells, comprising: (a) projecting infrared radiation on a sample of biological cells from different donor individuals, said radiation including a selected number of wavelengths; (b) recording spectral characteristics of said sample; (c) deriving a Fourier transform infrared spectrum (FT-IR) from the recorded spectral characteristics; (d) generating a derivative transformation of the FT-IR spectrum; (e) comparing said derivative transformation of the FT-IR spectrum with a reference FT-IR spectrum determined earlier of each donor individual; (f) identifying deviations of said derivative transformation of the FT-IR spectrum from said derivative of a reference FT-IR spectrum; and (g) confirming or denying that the biological cells in the sample originated from each donor individual based on the presence of said deviations.
