Does a single test cover everything?


Unfortunately not. There are different methods for different types of parasites. Our ParaQuest test is specifically a Roundworm faecal egg count floatation test using a centrifuge and the McMaster technique.

The McMaster technique uses a counting chamber which enables a known volume of faecal suspension (2 x 0.15 ml) to be examined microscopically, thus, if a known weight of faeces and a known volume of flotation fluid are used to prepare the suspension, then the number of eggs per gram of faeces (e.p.g.) can be calculated.

The quantities are chosen so that the faecal egg-count can be easily derived by multiplying the number of eggs under the marked areas by a simple conversion factor.
