The TearLab Osmolarity System is intended to measure the osmolarity of
human tears to aid in the diagnosis of Dry Eye Disease in patients
suspected of having Dry Eye Disease, in conjunction with other methods
of clinical evaluation. TearLab requires less than 50 nL (nanoliters)
of tear fluid and displays quantitative osmolarity resultsin seconds.
TearLab is for professional in vitro diagnostic use only.
