Faecal microscopy: UKAS accredited test
A concentration technique is routinely performed on all faecal samples for the presence of cysts, ova, and larvae.
Sample requirement: Minimum of ¼ specimen pot of faecal sample. Ova, cysts, and parasites may be passed intermittently therefore three samples may be required to be examined. Ova, cysts, and parasites will diminish over time therefore it is more ideal for the sample to be less than 2 days old upon receipt at LSTM, however older stools will not be rejected.
Culture for Strongyloides / Hookworm: UKAS accredited test
Faeces are cultured for filariform larvae using the charcoal technique.
Sample requirements: At least 50g (half pot) of faeces is required for this test. Ova, cysts, and parasites may be passed intermittently therefore three samples may be required to be examined.
Key factors affecting tests: samples should NOT be stored in a refrigerator/cold room following collection as this may inhibit subsequent larval growth.
