A variety of procedures are available to detect parasite eggs or oocysts in feces. This study compared the efficacy of simple flotation, a commercial assay, and various centrifugation techniques and three common flotation solutions. Results indicate that centrifugation consistently recovered more eggs than other methods. Proper technique is critical, including ensuring that the specific gravity of the flotation solution is correct and allowing the sample to stand for a sufficient amount of time before examining the coverslip. Because of the zoonotic health risks of many companion animal parasites, veterinarian and their staff should better utilize fecal examinations in their routine diagnostic plan.
有多种方法可用于检测粪便中的寄生虫卵或卵囊。本研究比较了简单浮选法、一种商业检测法、各种离心技术以及三种常见浮选溶液的效果。结果表明，离心法始终比其他方法能回收更多的虫卵。正确的技术至关重要，包括确保浮选溶液的比重正确，并在检查盖玻片之前让样本静置足够长的时间。由于许多伴侣动物寄生虫存在人畜共患病的健康风险，兽医及其工作人员应在日常诊断计划中更好地利用粪便检查。
