Present Status and Problems of Laboratory Test in a Community and at Home: "Sample Measurement Room", Self-Test and Mail-in Test

In this review, the present status and problems of laboratory tests outside traditional healthcare were dis- cussed. The test group includes the "sample measurement room", self-test, and mail-in test. They will be classified by 2 X 2 viewpoints, sampling/measurement X place/person. As for the "sample measurement room", consultation based on the results cannot be recommended, even if the results are abnormal, although this is often misunderstood. The problems of the "sample measurement room", self-test, and mail-in test can be considered from the viewpoints mentioned above. A sample extraction defect, infection between persons, the data instability by preservation, measurement error, and insufficient quality control are thought to be examples.
