Frequently Asked Questions


General questions
A sedimentation technique concentrates the potential intestinal parasites in a fecal sample by allowing gravity to settle them at the bottom of the sample.
A fecal floatation method concentrates the potential intestinal parasites of a certain weight range in a fecal sample based on the density of the solution used, allowing the organisms to float to the top of the sample if they are lighter than the solution.
A fecal sample can be stored up to 15 days (upright) at room temperature following homogenization. When ready, start from the beginning of the sample processing step and follow through to the end of the instructions.
Two grams (equal to two cones of solid stool or six spoons of loose stool).
PARATEST®, as supplied, does not contain any hazardous materials. Once you introduce a fecal sample, please follow your local and state regulations regarding disposal and recycling.
PARATEST® has shown great efficacy as a sedimentation technique in the fixing of common helminths, protozoa, and flukes. See comparison during in clinic use here.
After the 15 minute inversion, dispense and discard one drop then dispense a second drop on the slide to view.
Both video and written instructions are available on the PARATEST® home page (www.theparatest.com). Instructions for use are also provided with each purchase.
No, it is a self-contained single-use device.

The PARATEST® system requires less technician hands-on time than centrifugal or standard floatation methods. Additionally, there’s no risk of slide crystallization as can commonly occur when preparing a flotation read. The freedom PARATEST® affords the technician (both in terms of timing and the ability to prepare and read multiple samples consecutively) can be quite beneficial!
Unlike flotation methods, which require solutions of a particular specific gravity to accurately float cysts and ova, sedimentation concentrates all parasites and then filters them. Additionally, the properties of many flotation solutions can cause distortion and/or obfuscation of delicate cysts.
Everything from hookworms, tapeworms, roundworms, whipworms, and stomach worms, to coccidias, giardia, flukes and larvae can be identified using PARATEST®!
The filter is designed hold back debris and allow the parasites to flow through.
Yes, PARATEST® ECO Greenfix fixative can identify and maintain the morphology of all life cycle stages of giardia.
No, PARATEST® ECO Greenfix fixative can identify and maintain the morphology of all life cycle stages of giardia. Whereas in fecal floatations, a secondary test is required due to the distortion and degradation of the delicate trophozoites and cysts.
The recommended window is between 15-30 minutes.
The PARATEST® tray is the ideal mode for inversion and can hold up to 10 bottles at a time. Click here to be directed to the tray in our store.
PARATEST® should be stored protected from light as much as possible. To prevent unnecessary light exposure, do not remove sample cup from bag until sample preparation is required. If you have any questions on the ability of performance due to storage outside of the label claims, please contact technical support at 978-862-1801.
PARATEST® should be stored within these temperature ranges as much as possible. If you have any questions on the ability of performance due to storage outside of the label claims, please contact technical support at 978-862-1801.
PARATEST® should never be ingested or handled outside of its intended use. Please refer to the MSDS and seek a physician.
