Expression Of Interest in a Urine-based Interlaboratory Comparison
This collection of information contains Paperwork Reduction Act (PRA) requirements approved by the Office of Management and Budget (OMB).
Notwithstanding any other provisions of the law, no person is required to respond to, nor shall any person be subject to a penalty for failure to comply
with, a collection of information subject to the requirements of the PRA unless that collection of information displays a currently valid OMB control
number. Public reporting burden for this collection is estimated to be 10 minutes per response, including the time for reviewing instructions, searching
existing data sources, gathering and maintaining the data needed and completing and reviewing the collection of information. Send comments regarding
this burden estimate or any aspect of this collection of information, including suggestions for reducing this burden, to the National Institute of Standards

Instructions
Thank you for your interest in voluntarily providing information about your interest in and capabilities for a
potential metabolomics intercomparison exercise involving measurements on human urine samples. We are
gathering information regarding participant interest and capabilities so that we can make logistical decisions
about how to proceed. All expressions of interest are welcome; however, we may not be able to include every
laboratory that expresses interest in the exercise because of logistical issues.
At this time, the exercise is still being designed. The primary goal of the exercise is to assess reproducibility
of urine metabolomics analyses based on specific protocols for NMR, GC/MS, and LC/MS based measurements.
It will be important for participants to adhere to the established protocols as closely as possible to ensure
comparability of results. A small number of samples will be analyzed (<10) with participants providing raw
data, processed data and calculation results in standardized formats.
The data (raw and processed) and participant calculations will be used to assess the sample suitability for use
as a reference material, and the measurements will be used to develop consensus data concerning the
characteristics of the samples. All results will be reported anonymously, but participating laboratories will be
identified as exercise participants. We anticipate that the samples will be suitable for wide-spread usage in
urine-based metabolomics studies, and the samples will eventually be available for use by laboratories.
Please let us know if you would be interested in future interlaboratory comparisons with other types of
metabolomics samples.
If you have questions, you can e-mail us at (mailto:qmet@nist.gov)qmet@nist.gov (mailto:qmet@nist.gov).
