Our in-dwelling group of PhD-stage details experts harness statistical electrical power— reworking volumes of predictive data factors into actionable insights to assist determine the best models on your program and aid decision-making.
Typical processing protocols consist of a host of variables and selecting wherever and the way to start to make protocol adjustments is hard when this understanding and direction isn't built accessible. Dread of constructing changes that may result in worse processing and even most likely non-diagnosable tissue may well rightly reduce laboratories from acting. These perceived challenges, coupled Along with the time and Electricity to perform the validation of the potentially suspect protocol, may well show also intimidating for laboratories.
When the specimen is orientated, the margins need to be taken and labeled with respect to your orientation plus the margins ought to be marked just before grossing with indelible ink.
