Quality guidelines for next-generation sequencing.

The most recent meeting was held in December 2011 in Dubai. The objective of the deliberation was to evaluate the progress of implementation of the prior recommendations. Unfortunately, the goal of reporting the same units worldwide has not been realized. Dual reporting has been adopted by very few countries and has been transitory for the vast majority of these countries. Some countries have elected to report only SI units, while other countries have decided to maintain NGSP/DCCT units. Notwithstanding these developments, the meeting attendees recommended that both SI (IFCC) and NGSP/DCCT units be used for reporting Hb A1c in journals and other printed materials. To facilitate this goal, calculators to convert between millimoles per mole and percentage have been made available (http:// www.hba1c.nu/eng2.html and http://www.ngsp.org/ convert1.asp). Several journals have adopted this policy and all journals are encouraged to do so.
