PADs are currently available from the Lieberman research group at a cost of $2 per PAD + mailing costs. They are supplied in packs of 10 or 20 units that are heat-sealed in a metallized zip-top bag. Academic researchers and laboratory staff at drug regulatory agencies can obtain trial samples at lower cost--please contact Dr. Lieberman.
Training packs are available from the Lieberman research group at a cost of $40 per unit + mailing costs. The training packs contain 14 PADs, 14 training and certification samples, and PAD reading guides and logbooks.
PADs sealed in their packaging are stable for at least 12 months if stored in a refrigerator, and stable for at least 4 months under tropical conditions. Once the zip-top bag is opened, the PADs should be stored in the bag and used within 2 weeks.
