Abstract: Methods and devices implementing, for detecting a recirculation, at the side of a dialysis solution, by a blood-sided administration of a bolus are disclosed. Recirculation may be detected by: measuring a first light absorbance value (ad) of a dialysis solution (d) draining off a dialyzer using a spectrometer, prior to the administration of the bolus; venous administration of the bolus having a predefined volume (QBven) at the venous access; measuring a second light absorbance value (bd) of the draining dialysis solution using a spectrometer, after the administration of the bolus; and determining a change in the absorbance value between the first (ad) and second (bd) measured absorbance values due to the presence of a bolus in the dialysis solution during recirculation as a basis for the recirculation quantification.
