RNA expression reagents intended to aid in the determination of cancer diagnosis, prognosis, or treatment efficacy. These molecular assay reagents determine the level at which certain genes are expressed (i.e., the gene activity) in various sample types (e.g., cancer tumor tissue sample; biopsy sample from a lesion of unknown or indeterminate pathology; blood/urine sample, lymph node specimen). These tests typically use predetermined analytic algorithms to assess the RNA expression profile for patterns consistent with specific diagnoses, prognoses, or treatment effects.
