gel dif·fu·sion pre·cip·i·tin tests in one di·men·sion

precipitin tests in which antigen solution and antibody incorporated in agar are layered in tubes, permitting effective diffusion in the vertical dimension; the antibody-containing agar may be overlaid directly with antigen solution (single [gel] diffusion in one dimension).
