How to submit samples for analysis

It is strongly recommended that you contact the Metabolomics Core staff in the early stages of your project to discuss what measurements will be most appropriate to accomplish your goals.  Metabolites are susceptible to a large number of "pre-analytic" sources of variability that should be addressed before samples are collected.

The core staff has expertise in study design, sample collection procedures, storage and analysis. Individual consultations can be arranged by contacting the core director. Contact the lab.

When you are ready to submit samples for analysis, please complete this sample submission form. Email the form to Xuan-Mai (Mai) T. Persson and Ian R. Lanza, Ph.D. prior to sending the samples.

Samples should be packed in dry ice and sent to:

Metabolomics Core
Mayo Clinic Hospital, Saint Marys Campus
Alfred Building, Fifth Floor, Room 417
200 First St. SW
Rochester, MN 55905

If sending from outside of Mayo Clinic, please use an overnight carrier to ensure that samples arrive without thawing. Once we receive your samples, we will notify you by email and confirm whether they arrived frozen.

Your project will be placed in the analysis queue once received. When analyses are completed, you will be notified by email and provided with a link to retrieve the data. If necessary, we will arrange a post-analysis meeting to discuss the results and next steps if applicable.

Nonstandard service requests

The Metabolomics Core has a long history of innovation and novel methodology development. We embrace new analytic challenges and try to accommodate as many requests as we can. If there is a particular analyte or group of chemical compounds that you wish to measure, please contact the core director to discuss the project. Contact the lab.


National Institutes of Health (NIH) Public Access Policy requires that all publication that results from NIH funding be uploaded to PubMed Central. Review the process for uploading publications.
