Abstract
A method of assaying a sample of whole blood for one member of a specific binding pair, the method involving treating the sample with salt to alter the red blood cells in the sample to decrease their ability to pass through filter media, exposing the resulting sample to a filter which retains the red blood cells but allows the passage therethrough of filtrate of the sample containing the member of the specific binding pair, and measuring the member of the filtrate.
Claims14
A kit for assaying a sample of whole blood for one member of a specific binding pair, said kit comprising a first container holding a hypertonic solution, a second container suitable for containing a mixture of said hypertonic solution from said first container with the sample, a filter having a porosity to permit said mixture of said sample and said hypertonic solution to pass from said second container through said filter, said filter being capable of retaining the red blood cells in said sample, means for collecting the filtrate containing the first member of the binding pair, and means for detecting said one member of a specific binding pair with the second member of the binding pair.
