I appreciate the invitation to provide further discussion on measurement uncertainty to follow the recent article by James Westgard on the recent CLSI MU guideline. A hitch-hiker likes to keep things simple, have an easily understood map and reach the destination with minimal discomfort. This hitch-hiker’s destination is to briefly demonstrate to routine laboratorians, using minimal jargon and statistics, that MU is logical, easy to understand, useful and appropriate to implement in clinical laboratories [1,2].
