[Team Medical Care Involving Biomedical Laboratory Scientists].

As medical care becomes'more advanced and complex, increasing importance is being attached to the im- plementation of team medical care that provides appropriate care while making use of the advances, mutually cooperating, and supplementing the high-level specializations of various branches of medicine in order to provide safe care with peace of mind. Planned team medical care is demanded in this era, and the Japanese Association of Medical Technologists is developing various projects as well as promoting the participation of biomedical laboratory scientists in team medical care.

Multianalyte Conventional Reference Material (MacRM): A Useful Tool for Nationwide Standardization of Laboratory Measurements for Medical Care-A Model Study in Japan.

Background: The Japanese Committee for Clinical Laboratory Standards (JCCLS) has developed a multianalyte conventional reference material (MacRM) for nationwide standardization of laboratory measurements.

Methods: To prepare the MacRM, pooled sera were obtained from healthy Japanese individuals. Target values of the pooled sera for 30 analytes were assigned on the basis of the measurement results of 45 certified clinical laboratories whose calibration was verified by measuring certified reference materials (CRMs) provided by the National Institute of Standards and Technology, the Institute for Reference Materials and Measurements, and JCCLS.

[Histological detection of dried tiny thyroid tissue in health foods].

Two patients were diagnosed as having hyperthyroidism, and both had taken the same health food. We compared three kinds of histological methods to detect thyroid gland in this health food. The first method used cytology; the second applied the cell-block method; and the last is a modification of the cell particle (CPCB) method proposed by Ushijima.
