Tests and diagnosis

By Mayo Clinic staff

To help diagnose giardiasis, your doctor is likely to test a sample of your stool. For accuracy, you may be asked to submit several samples collected over a period of days. The samples are then examined in a laboratory for the presence of the parasites. Stool tests may also be used to monitor the effectiveness of treatment you receive.
