title: [Biochemical-Immunological Examination].
abstract: Abnormal laboratory values are often attributable to errors in pre-test processes, such as those in blood collection or sample treatment. Although these errors occur frequently, only a small percentage of them are detected, possibly resulting in misdiagnoses. In addition, when performing blood collection or sample treatment, not only doctors and nurses, but also medical technologists, who are conversant with laboratory tests, may generate abnormal values due to incorrect recognition or carelessness. On the other hand, although it is impossible to identify all abnormal values caused by pre-test errors in laboratories, the nonidentification of these errors will lead to iatrogenically abnormal values. Therefore, staff members conducting analyses are required to be familiar with many cases of abnormal values associated with blood collection, and to have skills to consider errors that may be responsible for the abnormal values identified. In this report, I present pre-test errors causing abnormal values, and measures against these errors.
