Magnetic-field-dependent fluctuation conductivity in the {ital a}-{ital b} plane of single-crystal YBa{sub 2}Cu{sub 3}O{sub {ital y}} is evaluated using recent theories for layered superconductors considering both Aslamozov-Larkin and Maki-Thompson terms. The normal resistivity, without fluctuation conductivity effects, is also estimated in the temperature region above {ital T}{sub {ital c}} using the parameters obtained from the analysis of the field-dependent fluctuation conductivity. The result is substantially different from previously estimated values that are linearly extrapolated from high-temperature data.
