Although this article is about fecal flotation techniques, combining flotation with antigen testing can minimize some of the disadvantages of flotation alone (BOX 1). Antigen tests can detect infections earlier than fecal flotation because they can detect parasites during the prepatent periods, before parasite eggs are present.
