When requesting a fecal culture and parasitology, please submit approximately 10 g of feces.
The differences between a Routine Flotation and a Modified Wisconsin are as follows:
- Routine Flotation is a semi quantitative test and reported as 1+, 3+ etc.
- Modified Wisconsin requires 5 g of feces that is weighed out and each different type of parasite egg, oocyst or cyst is counted for a more exact measurement of parasite load.
Sample collection/shipping
- Feces: should be obtained directly from the rectum. Ground droppings should be avoided because of environmental contamination.
- Skin Scrapings for mycology examination should be taken at the edge of the active lesion and submitted in a cotton plugged test tube or envelope.
