Abstract:
1. A method comprising: providing a group of known renal samples, each known renal sample having an associated known renal disease state, said known renal disease state including a renal oncocytoma disease state or a chromophobe renal cell carcinoma disease state; obtaining a Raman data set from each known renal sample; analyzing each Raman data set to identify a renal oncocytoma reference Raman data set or chromophobe renal cell carcinoma reference Raman data set depending on whether respective known renal sample is said renal oncocytoma sample or said chromophobe renal carcinoma sample; generating a first database containing all renal oncocytoma reference Raman data sets generating a second database containing all chromophobe renal cell carcinoma reference Raman data sets; obtaining a test Raman data set of a test renal sample having an unknown renal disease state; and providing a diagnostic of whether said test renal sample has a renal oncocytoma disease state or a chromophobe renal carcinoma disease state by comparing said test Raman data set against reference Raman data sets in said first reference Raman and said second reference Raman databases using a chemometric technique.
