Document Summary

Lecture 2: lab tests and their interpretation. The testing process: pre- analytical, patient preparation. Sample processing (separation, aliquoting: analytical. Sample analysis: review and acceptability of result, post- analytical, communication of result. Precision: how well repeated measurements on the same sample agree with one another how reproducible. Can you keep telling the same lies? . Accuracy: how close a measurement is to the true value. The best informed physicians are cognizant of the analytical performance of the laboratories that they use. Physicians well informed of lab tests, have a good idea of what an acceptable variation would be. Guassian curve on a guassian curve, this is what a distribution of results would look like. Within the - 1 and +1 sd limits, 68% of the time, results should fall within there. Within - 2 and +2 sd, 95% (or 19/20) of the time, results should fall within there.
