Medallion Labs does offer discounts. The discounts we provide are reviewed on a yearly basis for sustaining work, or are given to projects that have a minimum of 40 samples submitted. Please contact us if you have questions regarding discounts and we can assist you further.

Medallion Labs tests and reports all samples on an “as-is” basis. Results can be emailed, faxed and/or mailed to you. Email is the primary format for sending results. If you would like them faxed or mailed please specify on the submission form.

Our Laboratory Information Management System (LIMS) will report your results in units for the assays you request. All of your results will be reported on one Final Report unless you indicate otherwise on your submission paperwork.

Not all products are applicable to the methods we run, so please contact our Customer Service team for more information after reading the sample submission guidelines below.

Most of our Specialized Assays testing services require varying levels of consultation prior to testing.

Most of our Physical Properties testing services require some level of consultation prior to sending in samples. It’s important for our scientists to know your testing goals to ensure that the test is run correctly and reported in a useful format for you.

Our Flavor Characterization test requires a consultation prior to sending in samples to ensure we can test for the compound you require prior to accepting the sample. Most projects require testing of a minimum of two samples (a control sample and an off-flavor sample).   Contact us for a consultation to identify the nature, scope, and timeline of your project and include a completed Flavor Characterization Questionnaire along with your submission.

Our Shelf Life testing services require that our Shelf Life Questionnaire be filled out so that a protocol can be designed prior to receiving your samples. Challenge studies or micro-based shelf-life studies require additional consultation with our microbiologist in order to design and appropriately time the study as needed—however, please note that we require a filled-out questionnaire before your consultation can be scheduled.

If results are looking unexpected, we can discuss results or you can request rerun testing by reaching out to our Customer Service in form on this page.

Medallion Labs’ Rerun Policy:

If you notice a discrepancy in your testing results, you are encouraged to request a rerun. Our policy is to perform reruns in duplicate for testing run in our labs. If the rerun results are within our analytical method variability, you will be billed for rerun in addition to the initial run. If the rerun results are outside of our analytical method variability, you will only be billed for the initial run. If you believe that you need a rerun of your sample, please call our Customer Service team at 1-800-245-5615 for assistance. Reruns are dependent on the type of testing requested, and the amount of sample that is remaining after the initial analysis. In certain situations, a rerun may not be possible. Any reruns being performed by a partner lab will follow the partner lab’s rerun policies.

After results have been sent, all remaining sample, will be retained based on the amount of storage space available. Generally, samples are kept up to two months, but if our storage space does not allow, the samples may be discarded sooner. Paper copies of your testing results will be kept in an offsite storage facility up to 7 years after they have been completed.

Medallion Labs tests and reports all samples on an “as-is” basis. Results can be emailed, faxed and/or mailed to you. Email is the primary format for sending results. If you would like them faxed or mailed please specify on the submission form.
