US researchers in pathology and molecular biology help anatomic pathologists understand the significance of the wealth of molecular biological information that has recently become available and shows signs of continuing to increase. They begin by setting out basic molecular biology concepts and methods in a simple format with many illustrations. Then they survey the spectrum of currently used molecular tests in hematopathology, solid tumors, genetics, infectious diseases and identity testing.
