The ova and parasite (O&P) exam is used to detect the presence of parasites in a stool sample and help diagnose an infection of the digestive system (gastrointestinal, GI tract). Since there are many causes of GI infections, an O&P may be used in conjunction with other tests, such as a gastrointestinal (GI) pathogens panel or a stool culture, to help establish a diagnosis.
The best way is to avoid food and water that are potentially contaminated. This is especially true if you travel to emerging nations, where ice in a drink or a dinner salad may expose you to parasites. But the clearest mountain stream should also be suspect; it could be contaminated with Giardia. You cannot see most parasites; you won't be able to smell them or taste them in the water. If someone in your family has a parasitic infection, careful hand washing after going to the bathroom or handling soiled diapers can help prevent passing the parasite on to others
Treatment of diarrhea depends on the severity and duration as well as the cause. If diarrhea is uncomplicated and goes away within a few days, no specific treatment and only supportive care may be necessary. Supportive care typically includes drinking plenty of fluids (usually that contain salts and minerals) to avoid dehydration and sometimes modifying the diet. This may involve eating soft, bland foods such as bananas, rice, toast or crackers and avoiding foods that contain caffeine or ones with high fat content.
If the diarrhea is severe, bloody, contains mucus, and/or has lasted more than two days (24 hours in infants), you should consult your healthcare provider. Tests will be ordered to identify the cause of the diarrhea and then the treatment will be tailored to the cause.
Test Method 1 : A concentration procedure is performed mainly to separate the parasites from fecal debris. The concentration procedure not only increases the numbers of parasites in the sediment but it also unmasks them, making them more visible by removing organic and inorganic debris. In most cases the diagnostic parasitology laboratory does not know the consistency of the fixed(SAF) stool, therefore a full concentration and permanent stain are recommended.
The Formalin-ether sedimentation technique will be explain
Thoroughly mix the stool and examine looking for blood, mucous, pus and worms. The above case although extreme was submitted as stool for ova and parasite examination. If the stool was poured without gross examination these Taenia species proglottids may have been missed.
