ABSTRACT:
Apparatus for performing determinations of immune reactants (e.g., antigens, antibodies) in bodily fluids includes multiple test units having respective elongated rods with transversely-expanded tips at their distal ends. The tips are each coated with respective immune reactants (e.g., allergens of the type which react in a known manner with respective allergen-specific or allergen-binding antibodies in human serum. The test units are color-coded. By correlating the color code to a chart, the specific immune reactant (e.g., allergen) coating can be easily identified. The supporting strip for the test unit has through-holes which frictionally engage the proximal ends of the test unit rods with a spacing that permits all of the supported test units to be simultaneously inserted into an assembly of reaction containers arranged in a linear array. The through-hole spacing in the strip permits alternate test units to be simultaneously placed in an array of test tubes that are transversely larger than the reaction containers and supported in a linear array in a test tube rack. The tip of each test unit may take the form of two frusto-conical joined by a short cylindrical section extending longitudinally beween their larger ends. The frusto-conical sections may be multi-faceted to minimize scraping of the allergen coating from the tip during insertion and removal of the test units into the reaction containers/test tubes.
