Abstract
Un objeto de la presente invención es proporcionar medios de ensayo para la determinación del contenido de urea de los fluidos, en los que se consiga la estabilidad de los reactivos utilizados para la preparación de los medios de ensayo. Otro objeto de la presente invención es reducir a un mínimo las interferencia debidas a la turbidez del suero y a la presencia de bilirrubina, cuando se determina el contenido de urea del suero en sangre Todavía otro objeto de la presente invención es proporcionar medios den ensayo que tengan una especificidad y sensibilidad altas, para la determinación de urea en los fluidos, a lo largo de un margen de concentraciones. Aún otro objeto de la presente invención es proporcionar medios de ensayo colorimétricos, capaces de detectar urea, cuando la cantidad de fluido a someter a la determinación, es limitada. Un objeto adicional de la presente invención es proporcionar una determinación una determinación NUS, que pueda ser efectuada rápidamente, sin necesidad deun equipo altamente especializado De acuerdo con la presente invención, el medio de ensayo para detectar la ura presenta en un fluido de ensayo, comprende un miembro portador modificado con ácido, que incorpora reactivos separados entre si. Un reactivo es aldehido orto-ftálico, y el otro reactivos es 3- hidroxi-1,2,3,4-tetrahidrobenzo [h] quinoleina, 3-acetoxi-1,2,3,4- tetrahidrobenzo[h]quinoleína. o sus sales diclorhidrato. Ventajosamente, los reactivos están separados entre si, mediante un material polímero. El medio de ensayo puede ser utilizado mediante una inmersión momentánea del mismo en una muestra de ensayo, o introduciendo de otra manera la muestra de ensayo en la matriz portadora, y observando cualquier variación de color detectable que resulte.
