FIELD: medicine.
SUBSTANCE: proposed is a computer-implemented method for removing lipid traits with a weak signal. Technical samples without a biological signal and biological samples with a biological signal are obtained. The above samples are compared using a computing apparatus, wherein a threshold of 0.5 is set in a logarithmic scale with a base of two, between the mean values in the technical and biological samples. If at least one lipid trait has a less than 0.5 difference between the mean value in the biological samples and in the technical samples, said lipid trait is removed from the data.
EFFECT: invention reduces the influence of technical factors in the data of liquid chromatography with mass spectrometry by removing lipid traits with a weak signal.
