Abstract
The invention, in one aspect, provides a strip for tear collection. The strip has a first end and an opposite second end and preferably has substantially uniform cross-sections from the first end to the second end. The strip is made of a hydrogel material in substantially dry state. The strip is characterized by having a substantially uniform swelling along the hydrogel strip from the first end to the second end when fully wicked by a tear fluid and by having a correlation between the volume of tear uptake by said strip and the length of the wicked end portion of said strip. A strip of the invention is useful for assay of an analyte of interest in a tear fluid. The invention also provides a method and kits for assaying an analyte of interest (e.g., lactoferrin, glucose, herpes simplex virus, hormones, etc.).
