If you're not sure which type of parasite you're dealing with, or if you don't have access to one that has specific products against it, I suggest you try the parasite screening kits. I recommend the Poximeter, which you can buy here. The tests can also be done with urine or blood. This test is very easy to do, but is only a measure of parasite load. The Poximeter is only accurate to 2.5%, so don't rely on it as a cure for your parasite problem. To use the tests, you must put a little drop of your urine into a bottle and put the test on it. The test shows how many parasites you have. To make sure your tests are accurate, you must keep them in a dark place. That way, they don't get confused with other test results you receive. After you have tested, you should keep the bottle closed and discard it. It's very difficult to test for parasites because the parasites hide very well, so there is a great chance the tests may not be accurate. For example, I recently used the PDA test against a patient with multiple parasites. There are people who buy tests as a way of diagnosing a cold.
