No, it will only detect those that live in the digestive tract and whose eggs are passed through the stool. There are other tests specific for other parasites, such as pinworms, or blood parasites that cause malaria.
In populations living in adverse conditions due to poverty, a wide variety of intestinal parasite infections can be observed. These infections are usually diagnosed by stool microscopy, but can be easily missed if the procedures used are inaccurate or performed in a suboptimal way.
These findings indicate that at least three stool specimens should be examined to confirm the presence of intestinal parasites. Even with such practice, it is not possible to guarantee that there is no infestation, but examination of fewer specimens would run a definite risk of false negative results.
A stool ova and parasite, or O&P, test is a simple way of diagnosing parasite infections. This test determines whether parasites and their eggs are present in your stool. The stool O&P test is a common way to find out if you have parasites in your digestive tract.
However, parasitic infections still occur in the United States, and in some cases, affect millions of people. Often they can go unnoticed, with few symptoms. But many times these infections cause serious illnesses, including seizures, blindness, heart failure, and even death.
Some are common and some are very rare, found only in travelers or immigrants from areas where the parasites are common. Diagnosis is sometimes difficult and may require a specialist.
Endoscopy/Colonoscopy
Endoscopy is used to find parasites that cause diarrhea, loose or watery stools, cramping, flatulence (gas) and other abdominal illness. This test is used when stool exams do not reveal the cause of your diarrhea.
Nausea or vomiting. Gas or bloating. Dysentery (loose stools containing blood and mucus) Rash or itching around the rectum or vulva.
The signs of a parasite are often caused by the toxins that it releases into the human bloodstream. Here are the most common symptoms: Unexplained constipation, diarrhea, gas, bloating, nausea or other symptoms of Irritable Bowel Syndrome. You traveled internationally and got diarrhea on your trip.
Blood tests such as an eosinophil level -- a type of blood cell that is increased in many parasitic diseases -- can be helpful, and occasionally stool tests are of benefit. A few people need skin scrapings or even biopsy of skin lesions that can be evaluated by a laboratory to determine whether a parasite is present.
Stool microscopy is not a helpful diagnostic tool, since the worm eggs are deposited outside the intestine. Serological methods are of no diagnostic relevance.
Yeast and other fungal elements are common in stool. Depending on the size and shape, they may be confused for a variety of helminth and protozoan species.
Getting the Results
In general, the result of the ova and parasites test are reported within 2 days.
The etiological examination by staining is commonly applied to detect larvae, eggs, and cysts of parasite, while the examination with no staining is selected to detect parasite from blood and tissue fluid. Etiological examination is the most reliable way for a definitive diagnose of parasitic infection or disease.
Diagnosis for tapeworm infection is usually done through detection of eggs and proglottids (worm segments) via a stool test, although many patients' tapeworms are detected when they find proglottids in their own stool or in the toilet. It's not possible to determine which species of tapeworm is present without testing.
Stool specimens should be collected on three different days and examined in the lab for Taenia eggs using a microscope. Tapeworm eggs can be detected in the stool 2 to 3 months after the tapeworm infection is established.
Positive results mean bacteria, parasites, or other abnormal organisms were found in your stool culture. They may be causing your infection. Sometimes the test shows a false-negative result. This means the test missed certain infectious bacteria.
However, in some cases, symptoms may seem to be gone but will return after several days or weeks. Occasionally, people with giardiasis will have long-term complications such as reactive arthritis, irritable bowel syndrome, and recurring diarrhea that can last for years.
While Australia is free from many serious human parasitic diseases there are some parasites that we often encounter and are forced to deal with: Head lice. Dog Hookworm. Paralysis tick.
Some parasitic infections disappear on their own, especially if your immune system is healthy and you eat a balanced diet. For parasites that don't go away on their own, your doctor will generally prescribe oral medication. This treatment is generally effective and proven to work.
Gastrointestinal distress — since parasites take up residence in the intestines, this is where the most damage occurs. Diarrhea, constipation, gas, bloating, and nausea are all common symptoms of parasites. Weight loss — parasites can cause nausea and poor nutritional absorption, which can lead to weight loss.
Eat more raw garlic, pumpkin seeds, pomegranates, beets, and carrots, all of which have been used traditionally to kill parasites. In one study, researchers found that a mixture of honey and papaya seeds cleared stools of parasites in 23 out of 30 subjects. Drink a lot of water to help flush out your system.
There are many at-home tests for parasites. Testing for parasites at home is very easy. Our Ultimate and Advanced Gut Health Tests both test for parasites.
PCR Test - Bacteria
Technology for detecting parasites and other pathogens has improved dramatically since 2013. This PCR (polymerase chain reaction) test looks for the genetic fingerprint of a wide range of pathogens. This is a far more sensitive test than the old fashioned technique of looking through a microscope.
