of eggs per gram can be calculated as follows:
- Count the number of eggs within the grid of each chamber, ignoring
those outside the squares
- Multiply the total by 50 – this gives the eggs per gram
of faeces (e.p.g.)
12 eggs seen in chamber 1 and 15 eggs seen in chamber 2
= (12 +15) x 50 = 1350 e.p.g.
Do not delay reading the count beyond the recommended
the flotation fluid
may distort or destroy delicate eggs.
Therefore it is advisable to only process
a few samples at a time.
