We have made more than 8,000 PADs in the last two years--an amazing feat for our faithful spotting robot Dot the Bot and all the students who have participated in making the test cards.   

Where are all the test cards going? Many are used for test development, internal validation studies, and demonstrations or lab experiments at conferences or in classes.  Nearly a thousand have gone to Kenya for field trials, a hundred were used at the FDA, and 900 saltPADs were shipped to South Africa for an external validation study.
