The state of quality control: a critique.

Quality control of clinical laboratory testing must ultimately assure that test results consist of medically reliable information that is received where needed, when needed. This review shows that, despite the sophistication and complexity of current quality control procedures, numerous problems continue to prevent the achievement of this ideal. Solutions to some of these problems are suggested.

Analytical biases with liquid quality control material.

Biases were compared for eight analytes determined using common chemistry instruments. Data for three levels of liquid control sera were obtained from over 350 laboratories participating in a quality control program. These data were contrasted with comparable results for lyophilized material and reported in a CAP proficiency survey. In general, biases appeared to be proportional to analyte level. For some analytes, biases with liquid material were less than with lyophilized material, but for most analytes, biases were greater with liquid than lyophilized material. However, when liquid material is used for monitoring interlaboratory precision, the consequences of analytic biases are minimized because of large pool sizes.

The "stat" problem.

"Stat" testing is a major asset and a major liability of the hospital laboratory. The ability to perform critically important tests in large numbers with great speed and with reliable precision and accuracy has developed to a remarkable degree. Nonetheless, the demand for "stat" service so outstrips the supply in most hospitals that delivery of this service often falls short of the expectations of the physicians who order the tests with disturbing frequency.
