METHOD AND APPARATUS FOR MEASURING ANTIBODY LEVELS |
摘要 |
A diagnostic device is described employing a solid, rigid diagnostic substrate (having as a part thereof an exposed layer of first immunologically reactive biological particles) in combination with means spaced therefrom for containing a solution of second immunologically reactive biological particles specific to the first particles. Preferably these elements are arranged with the layer of first immunologically reactive biological particles on a glass slide having a metallized surface and facing the containing means with spacing therebetween. This spacing defines a wedge-shaped volume for containing test fluid. With a test fluid in place, after allowing diffusion to occur for a predetermined period of time, the extent of formation of a layer of the second particles (i.e., a second layer) on the first layer is determined. If such a second layer develops, this determination can be related to the concentration of first particles in the test fluid. Presence of the second layer is visible with good contrast to the unaided eye. |
