A method for assessing lung maturity in a fetus or an infant comprises adding a fluorescent dye to a pulmonary effluent, causing the dye to fluoresce by illumination with an excitation wavelength of monochromatic light, and measuring the intensity of the fluorescence at two different wavelengths. Alternatively, the method comprises sequential illumination with two different excitation wavelengths and measurement of the intensity of fluorescence caused by each excitation wavelength at a single emission wavelength.
