With Romanovsky stain or acid-fast stain). Special transport media are available for fecal cultures. Freezing will preserve feces for antigen-detection methods. Eggs and oocytes are resistant to degradation, and refrigeration will slow down embryonation, adequately stabilizing feces up to 1 day for flotation or sedimentation procedures. A variety of fixatives are also available to preserve feces for longer periods prior to flotation and/or sedimentation. Historically, formalin and mercuric chloride–based low-viscosity polyvinyl alcohol fixatives have been most widely used by parasitology laboratories for preservation of helminth eggs, protozoan cysts, and trophozoites in fecal specimens.

Faster systems require less exposure, but there is a relative loss of detail (spatial resolution). There is a trade-off between detail and exposure. Higher exposures mean increased exposure time, an increased chance of motion artifact and, potentially, increased personnel exposure. In addition to system speed, film type can significantly affect the latitude of the resulting radiograph. Film designed for human chest imaging has more latitude than generalpurpose orthopedic film. While such latitude radiographs are not as dramatic to look at and appear dull, there is inherently more information relative to a high-contrast radiograph made using general-purpose or orthopedic or mammography film.

In addition, bacterial flora continue to grow, potentially leading to overgrowth of a particular type of bacteria or yeast. Some bacterial species will sporulate. Immediate analysis is more important for some assays than others. For wet preparations used in looking for motile protozoa, accurate results require feces to be absolutely fresh (<5 min old), but appropriate storage methods are available for many other types of fecal tests. , with Romanovsky stain or acid-fast stain).
