This test is selected for determining a quantitative estimation of the number of viable microorganisms associated with medical products, raw materials or tissue samples. Validation of the processing methods should be validated (see MG063 and MG121). Bioburden testing is typically conducted to help select a material for a device or to help establish a sterilization method.  We employ both membrane and plate methods.
