摘要： A dry-type analytical element suitable for measuring the activity of alanine aminotransferase in a liquid sample, characterized by incorporating a dye capable of absorbing the electromagnetic waves of 400 to 500 nm into at least one water-permeable layer. The coloring sensitivity of the dry-type analytical element does not increase substantially even under a fluorescent light, and thereby, an accurate measured value can easily be obtained.
