dc.description.abstract | Purpose: To measure changes in the matrix metalloproteinase 9 (MMP-9) point-of-care test, InflammaDry (Rapid Pathogen Screening, Inc, Sarasota, FL) positivity, based on ocular surface MMP-9 concentrations and loading volume. Methods: Two different MMP-9 products, preform and active, were analyzed using the InflammaDry test, detecting MMP-9 levels of more than 40 ng/mL of both preform and active MMP-9. Preform MMP-9 (Natural human MMP-9 protein; Abcam, Cambridge, UK) was analyzed at different concentrations (50, 100, 500, 1000, and 1500 ng/mL) and loading volumes (5, 10, and 20 mu L). Active MMP-9 (Human MMP-9 protein; Novus Biologicals, Littleton, CO) was also analyzed using the InflammaDry test at different concentrations (50 and 100 ng/mL) and loading volumes (10, 20, and 40 mu L). Results: Natural human MMP-9 protein (preform) of 50, 100, and 500 ng/mL exhibited negative results for every loading volume. At 1000 ng/mL, the 20 mu L volume was positive, whereas the 5 and 10 mu L volumes were negative. At 1500 ng/mL, all loading volumes were positive, but the density of positive bands varied depending on the loading volume; larger loading volumes had higher band density. Human MMP-9 protein (active) of 50 ng/mL was negative for every loading volume. In 100 ng/mL, the 20 and 40 mu L volumes showed positive results with similar positive band densities. 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. | - |
