Patent ID: 6933109

Claim:
A method for detecting particles in a sample comprising; placing a fluid sample into a sedimentation container containing a first slanted solid phase, wherein the fluid sample is placed at a location above the first slanted solid phase, sedimenting particles in a sample across the first slanted solid phase to concentrate the particles; sedimenting the concentrated particles to a second solid phase; sedimenting the particles across the second slanted solid phase where the second slanted solid phase contains on a distinct part of its surface at least one immobilized binding agent capable of binding to at least one particle in the sample, allowing the particles to bind to the immobilized binding agent, and detecting particles bound to the immobilized binding agent on the second slanted solid phase, wherein the first and the second slanted solid phase are slanted with respect to a sedimentation path and wherein the sedimentation container is filled with fluid covering both slanted solid phases before sedimenting.
