Hi Aylin, Thank you for the updates. We have submitted this to our team for quoting. We will reach out if there is any additional questions, otherwise we should be sending the quote to you within the next 2-3 days. We would not need a baseline test for tis material as we are able to ensure it is negative for these in house.

We have a few questions to clarify the design before we quote this. Can you please reply to each of the following: 1. What fill size do you want for this? 10mL? (yes, it will be better) 2. How many total vials do you want to be quote for? (what's the minimum amount for the quotation) 3. Do you prefer frozen or freeze dried form? (preferring freeze dried to reduce the transport cost) 4. For Benzodiazapine, Barbiturates and Opiates, these are each listed 2x on the attached drug list. Can you clarify the specific analytes you are looking for each of these? (For Benzo and Barbiturate , 300 Cut off is suitable. For Opiate, 2000 Cut off is Ok, you can produce like this.) 5. For concentration, we are quoting 2 levels, the low control mean and high control mean, correct? (Yes, correct) Thank You,
