Abstract

SE PROPORCIONA UN TIRA DE PRUEBA PARA DETERMINAR LA PRESENCIA O LA CANTIDAD DE UN ANALITO EN UN LIQUIDO POR MEDIO DE INSERTAR LA TIRA EN UN APARATO DE LECTURA OPTICA. LA CINTA DE PRUEBA CUENTA CON UNA ZONA CON UNA GRADUACION DE ORIENTACION QUE TIENE UN FACTOR DE REFLEXION QUE CONTRASTA CON EL FACTOR DE REFLEXION DE LAS AREAS CONTIGUAS, Y, PARA ELLO, SE UTILIZA ESTA ZONA CON UNA GRADUACION DE ORIENTACION PARA ASEGURAR QUE LA CINTA DE PRUEBA NO HA SIDO INTRODUCIDA AL REVES CON RESPECTO AL APARATO.
