A woman wearing a white lab coat, blue gloves, and a green lanyard labeled "СМ-Клиника" is working in a laboratory. She is holding two blood sample tubes in her gloved hands, comparing them. The tubes are filled with a dark fluid and have light blue stoppers. There are other blood sample tubes with the same light blue stoppers arranged in a clear plastic rack in front of her. The laboratory appears clean and well-lit, with a white countertop, a window, and a piece of equipment visible in the background.
