Hi Sarah, We no longer retain samples from other manufacturing jobs so we don’t have that type of material available any longer. This has been quoted at our minimum order size to have some made up for you. It would be helpful to connect briefly so we can better understand your priorities and ensure we offer the best possible solution. Could we set up a quick call to discuss: • Your target price point for this order • The factors driving price sensitivity (e.g., internal budget, approval thresholds, purchasing policies) This conversation will help us evaluate options and make sure we’re aligned with your requirements. We’re always happy to work with you where we can.

In the past we have been able to purchase left over from other customs. Do you have anything like that?

Likely this could move faster but we would need to get the details to quote it in order to confirm. There is no obligation to purchase and this will get us lead time and pricing to help you evaluate options. If you want a quote we need to know: 1. What Matrix do you want it in? Urine 2. What fill size per vial do you want? 5mL 3. How many total vials do you want made? 10 4. List of the analytes with your target concentrations.
