What is the smallest sample I can send?

We routinely test animals weighing only a few grams, and in most cases very small faecal samples are sufficient for comprehensive parasite screening.

For small reptile samples, it may not be possible to provide numerical egg counts for pinworms where very limited material is submitted. Quantitative egg counting requires a minimum of 0.5 g of faeces. When smaller samples are received, pinworms (if present) will still be reported using a subjective scale (low / moderate / high).

Certain specialised tests require a minimum sample volume to ensure reliable results. For dog and cat tests that include Baermann (lungworm) testing, a minimum of 3 g of faeces is required in line with accepted diagnostic guidelines. If insufficient material is received, this component of the test may not be possible. Pooled samples are recommended as some parasitic forms may be shed in low levels or intermittently.
