Measuring errors in surgical pathology in real-life practice: defining what does and does not matter.

abstract：:The cases of 20 patients, each of whom has a positive lupus erythematosus cell preparation and a negative antinuclear factor test, are presented. The concept of a false-positive lupus erythematosus preparation is suggested. Five common mechanisms causing a false-negative antinuclear factor test are discussed and evalu...
