Faecal egg counts are performed using the industry standard modified mcmaster counting method, and presented as an EPG (eggs per gram) value.
The sample of dung is weighed into a test tube and Magnesium Sulfate (MgSO4) solution added to a specified level. After preparation, the sample is then spun in a centrifuge at 3000 rpm for a set amount of time. This allows the worm eggs to float to the top of the mixture and the debris to settle to the bottom, giving better egg recovery. The top layer of liquid is then syphoned off into a double chambered mcmaster slide. After 2 minutes time to allow any eggs to float to the surface, the slide is then counted underneath a 100x magnification microscope. The eggs counted are then calculated using the modified mcmaster calculation which then gives an "eggs per gram" value.
All of the lab equipment used for testing is high quality lab ware which is reusable, rather than using disposable plastics which are bad for the environment. Every item is sterilised between tests.
Before testing all samples are stored in a refrigerator to slow down egg development allowing more time for an accurate result. All samples are processed the day they arrive here and results reported, giving you a speedy and accurate service.
