Westgard. Which improvements should be made first? Unfortunately, we seem to be arguing that http://www.medscape.com/viewarticle/758467_4 some errors are more important (i.e. worse) than others. But rather than make a Chicken-or-Egg choice, David Plaut, Dr. Westgard, and Sten Westgard urge an analysis of these types of errors. The answer to the question of which improvements come first need not be "pre" or "post" or "analytical" https://www.westgard.com/guest20.htm - it should be "all three at once." Whose errors are more "obvious?" A Half-Baked Analogy Which errors are worse? Which improvements come first? A final thought Making sense of conflicting priorities in the laboratory We've often heard the opinion that the Quality Control of laboratory testing isn't the biggest problem we're facing. Sometime people quote a statistic that 40% of the errors in the laboratory are pre-analytical, 40% are post-analytical, and "only" 20% are analytical. There are more "P-errors" than "A-errors", therefore, many laboratories believe they should put a higher priority on pre- and post-analytical errors than on analytical errors. First of all, you may find it depressing when we admit we've got problems everywhere and we only argue over which problems are worse, which problems will be fixed next, and which problems will be ignored for the time being. Ignoring problems is not a

Possible causes of analytical errors includes: incorrect measuring of the sample or reagents; usually these are dilution or pipetting errors; using reagents that have been improperly stored, or after their expiration date.
