The invention relates to a method for determining a presence of microorganisms in an agar component (10) comprising an agar, the agar having nutrients conducive to the growth of microorganisms, the method comprising: - a) obtaining the agar component, extending between a first end (11) and a second end (12), and being at least partially transparent to an illumination wavelength; - b) arranging the agar component obtained in a), in contact with an ambient medium (2, 10, 14, 15), the ambient medium having a refractive index lower than the refractive index of the agar, so that the agar is capable of confining light, at said wavelength; - c) illuminating the first end by a light source (21), and detecting, by the photodetector (22), light emanating from the second end after it has propagated between the first end and the second end; - d) repeating step c) at different times; - e) from a variation of the light detected at different times, determining a presence of microorganisms in the agar component.
