SIBO Breath Test - No Substrate

Use this test with your own lactulose or fructose. This is Dr. Siebecker's preferred 3-hour, 10-tube SIBO breath test format. - Lactulose must be obtained/prescribed separately (10g lactulose/15ml). Use 15ml in 8 oz water, for each test. - Fructose is sold on amazon and in grocery stores: use 25g in 8 oz water, for each test. - Interpretation is not included in this service. Dr. Siebecker will not see or review your test, is not involved in this order and is not your doctor. - NOTE: You will not be notified when results are ready. Please check back for your results.
