AMT project for the derivation of reference intervals in Japan
Journal Title: Journal of Analytical Bio-Science - Year 2011, Vol 34, Issue 3
Abstract
To obtain reliable laboratory test results anytime or anywhere, the JAMT (Japanese Association of Medical Technologists) and the JCCLS (Japanese Committee for Clinical Laboratory Standards) have been proceeding with a revised standardization of clinical laboratory tests. Therefore it has been considerably achieved in Japan. However, the reference intervals of laboratories often differ. This study aimed to establish reliable reference intervals in Japan. A total of 105 laboratories, in which the traceability was assured by carefully measuring certified reference materials took part in this project. A total of 3371 reference individuals (male 1348, female 2023) was used for a derivation of the reference intervals based on the parametrical method. The ANOVA clarified that there were obvious inter-gender differences in 12 items and between-age differences in 16. The most important finding of this study showed that no existence of regional distribution examinedany where in Japan.

Development of assays for measuring HBV- and HCV-related markers
Several decades have passed since HBV and HCV were identified, and many assays for measuring HBV/HCV-related markers have annually developed. These assays have contributed to the development of kinetic analysis, diagnosi...
Lipophorin: lipid-transfer protein in insect blood
Lipophorin is one of the major lipoproteins in insect blood. It contributes to the transportation of several lipid classes. Its particle weight is about 600 k with two apolipoproteins, apoLp-Ⅰ and -Ⅱ (MW=250 k and 80 k,...
