The list of medical tests mentioned in various sources as used in the diagnosis of Ascariasis includes:
Your health care provider will ask you to provide stool samples for testing. Some people notice infection when a worm is passed in stool or is coughed up. If this happens, bring in the worm specimen to your health care provider for diagnosis. There is no blood test used to diagnose an ascarid infection. (Source: excerpt from Ascaris Infection: DPD)
A large number of larvae invading the lungs at one time may cause pneumonia. This stage of the disease precedes the intestinal phase by weeks, and the symptoms are difficult to diagnose. Once mature female worms are present in the intestine, however, a doctor can diagnose the infection by finding characteristic eggs in the stool.

CONFIRMING DIAGNOSIS The key to diagnosis is identifying ova in the stool or adult worms, which may be passed rectally or by mouth.
When migrating larvae invade alveoli, other conclusive tests include X-rays that show characteristic bronchovascular markings: infiltrates, patchy areas of pneumonitis, and widening of hilar shadows. In a patient with ascariasis, these findings usually accompany a complete blood count that shows eosinophilia.
