If you see a doctor about passing parasites be prepared for the doctor to either not believe you or.....do a lab test. If the lab test is done it will probably come out negative. Lab tests for parasites are not reliable because to get positive results, the sample must contain either a worm or the eggs. Even it if does, the technicians are not well trained in parasitology. In other words, they do not know what they are looking at. Save your money and continue with the parasite cleanse you are doing.
