Inspection for Thread Worm Eggs; Instructions in English
[15 June 2001 - http://www.tokyowithkids.com/fyi/hoikuen/threadworm.html]
Take an imprint of the child's anus upon waking up in the morning, BEFORE the child goes to the toilet.
Do this on two separate mornings (they do not have to be consecutive).
There are two blue "bull's eye" targets, one for each morning. Peel back the celephane cover, do the imprint and re-cover. The second day do the same procedure with the second blue "bull's eye". Then peel off the celophane cover for both and put the first and second imprints together. Avoid any air bubbles inbetween.
Return to the day care center before the deadline.
