Hi Sharlie, Thanks for the detailed specs—happy to price this using the same format/amount you order for your current Methamphetamine Plus control. We need some additional information to submit your request for a quote. If you could please complete the chart below, it will help with the submission of a quote. If you have any questions, please do not hesitate to contact us. Customer Design Details 1. Matrix (i.e. urine, serum, blood, etc.) Defibrinated plasma (please confirm) 2.

Shipping Address (company, attention, street, city, state, ZIP, phone) A couple quick notes based on your questions: • Expiration: Labelled shelf life is primarily driven by form (frozen ≈18 months; freeze-dried ≈30 months). Adding these three analytes typically does not extend expiry on its own; we’ll confirm final dating after formulation/stability review. • Evaluation sample: We can provide a small pilot/evaluation lot before shipping out the full product. Please indicate vial size and how many you’d like for testing. Please let us know if you have any questions, have a wonderful day! Thank you,
