  • Method for producing a quality assured biological sample and composition containing the same
    Patent number: 6649339
    Abstract: A method for producing a pool of biological samples that is quality assured with respect to the load with microorganisms, using a nucleic acid amplification method, in which a screening pool is tested with a high sensitivity nucleic acid amplification method and can be divided into screening subpools, which are tested with a less sensitive nucleic acid amplification method, where individual samples can be picked out and eliminated, is described.
