flotation method

flo·ta·tion meth·od

any of several procedures for concentrating helminth eggs for more reliable results when eggs are difficult to find in direct examination; the flotation methods depend on flotation of helminth eggs on the surface of a liquid of sufficiently high specific gravity, approximately 1.180; one part feces mixed in about 10 parts saturated saline will float most protozoan cysts and nonoperculated helminth eggs.
