Some studies, but not all, will have auto resupply. In order to trigger this service, sites need to notify Covance when you have an expired or damaged kit. It is important to keep your kit inventory updated in order to have auto resupply orders trigger properly. You can notify us about your kit inventory via the kit order website: http://www.covance.com/kitordering. Please fill out the required fields and write the kit name and inventory number under the comments section.
