Levi Jenning Chart

By Dr Mohammad Moharram1/8/2020


  • Levi Jenning chart is one of the most important quality tools in the medical laboratories. It is installed in most automated analyzers. Some analyzers don't have L.J. chart. Sometimes the built in L.J. chart doesn't work if you don't use the analyzer specific control. Some built in L.J. chart use only the assigned company mean and standered Deviation. That is why you must have your own L.J. chart. I tried to make an excel sheet for L.J. chart that will be helpful as a quality tool. I considered the required quality data by most accreditation organizations.
