Turnaround times
The quoted turnaround time is from sample receipt in the laboratory, to results authorisation in the Laboratory Information Management system. The times do not include transport of specimen to the laboratory or the administrative process to print and post/email reports. Service users must allow for transport and reporting time when ordering tests.
Clinical background:
Although faecal specimens are the most commonly received samples for the detection of parasites, they may also be detected in a variety of other clinical specimens submitted to the laboratory e.g. terminal urine.
Specimen container paediatric:
- Scoop faeces in to Universal using integrated spoon.
- For Schistosoma haematobium, please send a sterile white topped universal with urine collected between 10am and 2pm.
- If investigation for threadworm ova is required, please send a perianal swab. A dry cotton swab should be used to sample the rectal area before placing in to a sterile universal container with 5ml sterile saline.
