I have no idea. All i know is that my daughter was DX'd by ER doctor as pinworms. After we all had a dose of albenza and flushed oit with laxatives, we all started seeing white things in our poop. Some are tiny abd bright whiteabd others are off white and like rice ill uploadpics in a minute. I took some for the doctor I'm going to see her today. My 8 yr old only has the white and my 5 year old has the snake skin sausage casing/snake skins (i get those too) and what looks like a half grape in her poop. I've been passing crazy stuff like white spots, snake skins, grapes and now ijust crapped out 2 huge stem or wood chip looking things. I cant get good pivs because i have the container in the fridge and ita foggy, but the small one is somewhat viewable. Lemme go upload pics quick
