It is important to bear in mind that common diseases, such as atrial fibrillation and stroke, occur as a result of the interplay of both environmental (including lifestyle and other health and medical conditions) and inherited risk factors. As a result, having a specific genetic risk factor for a common disease does not mean that one will necessarily develop the disease; and not having a certain risk variant does not eliminate the possibility of developing the disease.

The positive result indicates that HIV-1 antibodies were detected by the laboratory analysis in the individual's blood sample that was submitted. The infected individual is capable of passing the virus to someone else. The individual must immediately seek a physician for medical advice and treatment.

It is very important to realize that because there are a number of risk factors of atrial fibrillation, including both genetic and lifestyle/health factors, receiving a negative result for the deCODE AF? test does not mean that one is at low or no risk of AF. Back to top of page

There are 4 possible test results: "negative", "positive", "indeterminate", or "result not available." A "negative" test result means antibodies to the hepatitis C virus were not found in your test sample and it is extremely unlikely that you have been infected with the hepatitis C virus.

It means a laboratory could not confirm the presence of Hepatitis C antibodies in a particular blood sample. It could mean that an individual may be in the process of converting from being negative to being positive. It could also be due to other medical factors. In either case, it is recommended that the individual be re-tested.

If your first test is positive, a second test using the same blood sample will be performed to confirm the first result. If the second test also is positive, an additional confirmatory test will be performed to make sure your results were not "false-positive." If the third test is positive, it means you are infected with HIV. However, it does not mean that you have AIDS. The average time from HIV infection to an AIDs diagnosis by a physician is usually seven to 15 years.

No. More than likely you caught your surge on the way up and again on the way down. Your true surge would probably have occurred sometime between the two tests.

The first documented cases of AIDS was on the 5th of June 1981, in the USA, and five people were affected with the disease. However there were reported (but not documented) cases of occurrence of HIV in 1959, But not much information was gathered on the later event. REF: FIRST OUTBREAK OF AIDS

A positive TB test means that someone has been exposed to the TB germ and follow up evaluation is needed. Once a positive TB test has been confirmed to be truly positive, there is no point in having repeat TB tests in the future. They will not hurt you, or cause disease, but will always continue to be positive. BCG vaccine (Bacille Calmette-Guerin) used in countries where TB is endemic, can decrease the severity of TB in children but will not prevent TB infection.

individual with two copies of the risk variants will receive a positive result for deCODE MI™, and those with only one or no copy of the risk variants will receive a negative result for the test. Back to top of page

An insufficient blood result refers specifically to the Home Access® Hepatitis C Check Test system. It means that the Hepatitis C test could not be performed on the blood sample that was sent to the laboratory. This happens most often because there was not enough blood to test, there were white spots in the circle, or the blood did not soak through all the way to the back.
