Maico-Diagnostics, Eden Prairie, Minn, features the EroScan, a versatile, portable diagnostic otoacoustic emissions test device that measures OAEs in 10 to 30 seconds. Testing can be performed by nurses or trained volunteers and no interpretation is needed, nor is any response necessary from the patient. Users can customize the testing parameters and the data quickly transfers to a printer or an optional EroScan database program for very low, disposable costs. Maico provides a free demonstration video, as well as the Guide to OAEs for Newborn Screening. (888) 941-4201; www.maico-diagnostics.com.
