Matrix samples allow you to screen the starting material, prior to manufacturing, for interference with your test method or analytes of interest that are not tested in our in house ELISA screen. Adding a matrix sample to the order typically adds 1-2 weeks to the manufacturing lead time and can increase the per vial price of the material. Matrix samples are required when the analytes of interest are endogenous to the human body, to determine a baseline reading prior to manufacturing.

We manufacture and spike products gravimetrically; we do not test in-house to confirm concentration. We have been making products this way for over 40 years and are confident in our manufacturing accuracy. However, if you select this option, we will send this product to a 3rd party lab and provide a single run reference point confirming the concentration of the material. This process will extend the manufacturing lead time by 3-4 weeks. The actual cost each test will be included on your quote. We guarantee our products whether you select this service or not. If you have any issues with your material please contact us for support.

If you select this option we will send you 1 vial of each level of this product after manufacturing completes, to test for approval prior to shipping the full order. Once you have completed the approval process, there will be an approximate lead time of 1-3 business days to receive your full order. There is no charge for this service. We guarantee our products and we will support you with any issues regardless of whether you request a validation sample or not.
