Abstract

La invencion describe un metodo y aparato para determinar el volumen de celulas de sangre roja sencilla u otras particulas que estan suspendidas en liquidos. La muestra se dispone en una cubeta optica apropiada para analisis microscopico. Se anade un tinte fluorescente que no se fuga hacia las celulas, y que es capaz de absorber luz de excitacion y emitir luz de fluorescencia a longitudes de onda que son absorbidas solamente de manera debil por las celulas. El volumen de celula se determina utilizando los valores de intensidad de fluorescencia medios (i) en una primera area que comprende una sola celula, y (iii) en la segunda area, despues de cambiar el espesor de cubeta en una cantidad conocida.
