Interference-eliminating membranes, test strips, kits and methods for use in uric acid assay

摘要

The present invention relates to an interference-eliminating membrane for use in detecting uric acid in a sample comprising: (a) a compound for inhibiting or shading uric acid interfering substances or a derivative thereof; and (b) a carrier having an absorption property and permeability of the sample, wherein the said compound for inhibiting uric acid interfering substances can selectively oxidize a substance having a reducing ability higher than that of the uric acid in a sample and the said compound for shading uric acid interfering substances carries one or more mercapto groups. The present invention also provides a test strip for use in detecting uric acid in a sample and a kit comprising the test strip of the invention.
