Abstract: A method for detecting and counting particles suspended in fluids, such as bacteria suspended in urine, utilizing dynamic features of the suspended particles and employing light scattering measurements. The disclosed method is suitable for determining the susceptibility of bacteria to antibiotics. A cuvette for detecting bacteria in fluids, which is especially suited for the light scattering measurements, is provided.

Abstract: The present invention is an optical measurement system for measuring a liquid sample within a well. The system comprises a light source configured to transmit light though the well, a detector configured to measure optical signals derived from the transmitted light, and a tunable optical element. The tunable optical element is positioned between the light source and the well. The tunable optical element is operable to shape the light to compensate for distortions induced by a surface of the liquid sample. The detector is preferably located below the well for receiving a forward scatter signal indicative of at least one characteristic of the particles within the liquid sample.
