Abstract
A process for the sampling of extracellular fluid across the skin of an animal involves establishing an ultrasonic standing wave across the skin and collecting fluid transudate. Sampling can be enhanced by combining the use of ultrasound with the application of a partial vacuum to the surface of the skin. An apparatus includes an ultrasonic transducer, a reflector and an absorbent material for collecting transudate. The apparatus can further include a pressure component for reducing hydrostatic pressure on the skin surface.
