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.
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.
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.
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.
