Test information
Indicate clearly which investigations are required. Give history of recent foreign travel.  If Enterobius vermicularis (threadworm is suspected) a moistened perianal swab in charcoal transport media is preferable.
Pre-analytical
All specimens should be transported and processed as  soon as possible although contact lenses, cases and fluids will withstand posting and a delay of several days. 
If prompt examination of stools cannot be carried out, the use of 10% formalin- water  preservative  is  necessary  to  prevent  deterioration  of  protozoan morphology, the  hatching of first-stage hookworm larvae, and overgrowth  of yeasts. 
Any materials used in taking these samples must be discarded in an approved clinical waste and/or sharps container. 
If a delay occurs in transporting the sample to the laboratory please refrigerate.
