Several manufacturers now have available single-vial stool collection systems, similar to the SAF or modified PVA methods. Some of these formulations are advertised as “ecologically friendly” and do not contain either mercury or formalin. From the single vial, both the concentration and permanent stained smear can be prepared. It is also possible to perform fecal immunoassays (EIA, FA, or the rapid-flow assay) with samples from some of these vials. Make sure to ask the manufacturer about all three assays (concentrate, permanent stained smear, and immunoassay procedures) and for specific information indicating that there are no formula components that would interfere with any of the three methods. Like the zinc substitutes, these formulas are proprietary.
