Find more eggs!! Recent studies have proven that centrifugation of fecal samples is for more effective than traditional standing passive flotation. Furthermore, a flotation media must have a higher specific gravity than 1.20 to float many of the common parasite ova. Sheather’s sugar solution has a specific gravity of 1.27 which is high enough to float any ova.
Basic Physics: If an ova has a higher specific gravity than the flotation solution, it will not float nor will it be detected.
