A NEGATIVE result from a Hemoccult II test means that there was no evidence of occult (hidden) blood detected in your stool specimen. However, this test is not a complete cancer detection examination; it only detects blood in the stool.
Talk to your doctor about the meaning of your specific test results. A negative value usually means that alcohol, prescription medications that have not been prescribed, and illegal drugs have not been detected. A blood toxicology screen can determine the presence and level (amount) of a drug in your body. Urine sample results are usually reported as positive (substance is found) or negative (no substance is found).
