How is ascariasis diagnosed?

Once the infection has reached your intestines, your healthcare provider can diagnose the infection using a stool sample. The test involves looking for eggs or live worms in your poop.

If the infection is in your lungs, it can be more difficult to diagnose. Your provider can confirm a diagnosis by finding evidence of the larvae in your lungs or stomach fluids.

Sometimes people cough up a worm. In rare cases, you may even see one come out of your nose. If this happens, bring the worm to your healthcare provider so they can examine it.
