Changes in the Matrix Metalloproteinase 9 Point-of-Care Test Positivity According to MMP-9 Concentration and Loading Volume

Conclusions:
The InflammaDry test had a different detection range depending on MMP-9 formulas; higher concentrations of preform MMP-9 protein were needed to yield positive results. In addition, InflammaDry positivity varied based on the loading volumes. Clinicians should be aware of the possibility of false negatives with low tear volumes despite elevated MMP-9 concentrations.
