A new JCCLS standard on Molecular Methods, English version, is available and uploaded

An Approved Guideline for the Quality Management of Specimens for Molecular Methods: The Procurement, Transport, and Preparation of Specimens” This document provides guidance for addressing molecular diagnostic methods used in routine medical laboratories worldwide.

An Approved Guideline fo


Reference Standard-JSCC Enzyme, the JCCLS-CRM (JCCLS-Certified Reference Standard for Enzyme of JSCC method), can be purchased from JCCLS

  1. Standardization for enzymes in Japan are successful enough to converge within approximately 3% of CVs between laboratories, which is owing to the establishment of traceability chain with the JCCLS-CRM, a certified reference standard for enzymes, being composed of human recombinant enzymes.
  2. Reference measurement procedures (RMP) of enzymes in Japan (JSCC consensus??? method) are not always the same with IFCC RMP. ?Catalytic activities of 7 kinds of enzymes on the JCCLS CRM were measured by IFCC RMP in an accredited laboratory and compared with those of JSCC method (in detail, see PDF A and PDF B ).
  3. We received Rerence Material Producer Accreditation Certificate on March 29, 2013, and the JCCLS-CRM is produced under this certificate. This certificate is based on ISO guide 34:2009, and ISO 17025 regarding assignment of property values (see PDF C ).
