ATD TearScan™ 300 (Deposit Only)


This compact, inexpensive lab testing device can fit easily into any working clinical practice, with a footprint about the size of a toaster.

The TearScan™ uses cartridge-mounted test strips to process very small samples of collected tear fluid (0.5 L) and tests for the concentration of Lactoferrin and Immunoglobulin E (IgE). Lactoferrin can confirm, or rule out, Aqueous Deficient Dry Eye Disease and the IgE test can confirm, or rule out, the presence of an ocular allergen.
