General Questions
Medallion Labs is anISO/IEC 17025accredited testing laboratory. Our accredited status means that our Quality Management System and in-scope analytical methods meet the stringent requirements of an internationally recognized standard of quality for testing laboratories in the Food and Pharmaceutical industry. Our full scope and certificate of accreditation can be accessed in the About Us section of our website. You can also obtain the information from our accrediting agency’s website:a2la.org– certificate numbers 2769.01 and 2769.02.
Our standard turnaround time is 10 business days for most assays. There are some assays that require a longer turnaround time. We also offer a RUSH service that is half the time of the standard turnaround time of the assay at double the cost of the assay. A few assays that we provide cannot be rushed due to the nature of the test. Please check the specific assay you are interested in regarding the ability to RUSH the turnaround time.
At Medallion, we try to offer the most sophisticated and current testing capabilities, and strive to keep our website up to date with our recent test offerings. If you do not see the analysis you require, please contact our Customer Service team at 1-800-245-5615. If we cannot run the assay you need, we will do our best to recommend you to another lab that can fulfill your request.
We make every effort to keep our methods and detection limits up to date according to the latest standards and qualifications. If you have any questions regarding the limit of detection/quantification or method references, please contact our Customer Service team at 1-800-245-5615.

Most of ourSpecialized Assaystesting services require varying levels of consultation prior to testing.
Most of ourPhysical Propertiestesting 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.
OurFlavor Characterizationtest 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 usfor a consultation to identify the nature, scope, and timeline of your project and include a completedFlavor Characterization Questionnairealong with your submission.
OurShelf Lifetesting services require that ourShelf Life Questionnairebe 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.

Analysis/Results Questions
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.
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’ 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.
