Genetic testing covers tests that need to be evaluated to uncover genetic variations, mutations, traits and predispositions. This testing can also be used to predict an individual’s response to a therapy or other treatment. Gene expression tests look for activation of genes—specifically measuring the amount of messenger RNA (mRNA) resulting from its corresponding gene. Because activation levels differ depending on the point in time, gene expression tests can be used multiple times. Each time the AlloMap test is performed, the gene expression of 20 genes (11 informative, 9 control) is measured.
