  • Test piece for albumin measurement
    Patent number: 12117451
    Abstract: A dry test piece for albumin measurement is based on the improved BCP method as a principle, and enables the measurement of albumin at a high sensitivity. The test piece includes a support; and a reagent holding layer provided on the support and on which a sample is spotted. The reagent holding layer contains a protein denaturation agent (component A), an SH reagent (component B), bromcresol purple (component C), and a nonionic surfactant (component D). In the reagent holding layer, a weight ratio (D/C) of the component D to the component C is 0.3 to 13, a content of the component C relative to an amount of the spotted sample is 0.4 ?g/?L to 5.4 ?g/?L, a content of the component D relative to the amount of the spotted sample is 25 ?g/?L or less.
