The present invention relates to a kind of diagnostic tool casees, and DNA chip method, for diagnosing or monitoring treatment carcinoma of testis, these are of great importance, and particularly, are giving protection against cancer and are post-processing. The present invention be substantially it is characterized in that in testicular tumor marker mRNA detect blood sample, thus tumor markers describe tumor-related gene expression. For this purpose, especially β-hCG, AFP, PLAP or GCAP are discussed. Detection mRNA amplifies in cDNA and then the cDNA of selected segment by reverse transcription, passes through polymerase chain reaction.
