The world of laboratory medicine is rapidly evolving from a limited set of assays that probe individual analytes by basic biochemical and immunologic methods, to a complex high-tech realm in which hundreds and thousands of analytes are simultaneously evaluated. These newer methodologies share both the advantage of a wealth of detailed information and the issues of quality control, data manipulation, and interpretation. This chapter provides a primer on the various technologies behind gene expression profiling, array comparative genomic hybridization, array single nucleotide polymorphism assays, methylation profiling, and proteomics. Special attention is also given to some of the interpretation methodologies; examples of the application of these techniques to hematologic disorders are given.
