Claim 3:
4. The method of claim 1 wherein identifying the presence of a specific disease in the test patient's biological sample further comprises:
obtaining the test patient's biological sample using an invasive procedure, wherein the types of biological samples comprise blood or tissues;
extracting the test patient's gene expression profile data from the test patient's biological sample using microarray technology in a laboratory, and normalizing the test patient's gene expression profile data;
generating a new matrix of gene expression profile data of disease specific fingerprint genes by disease specific true positive patient biological samples from the fingerprint gene data matrix to also include the test patient's gene expression profile data in the new matrix, to identify using the fourth PCA layer, presence of the specific disease in the test patient's biological sample;
generating, using the fourth PCA laver, principal component vectors by performing linear transformation on the new matrix of gene expression profile data wherein two largest variance principal component vectors are selected to create graphical plots on a computer display screen that classifies the test patient's biological sample as disease or healthy;
identifying presence of a specific disease if any, from the location of the test patient's biological sample in the graphical plot on the computer display screen, wherein the location of the test patient's biological sample amongst the disease specific true positive samples in the graphical display plot indicates the presence of the same disease as that of the disease specific true positive samples, while the location of the test patient's biological sample distanced from the disease specific true positive samples in the graphical display plot determines that the test patient's biological sample does not have the same disease as the disease specific true positive samples.
