The Positive Control powder on the surface of the water is not completely dissolved and causes an overreaction with the test tissue. The overreaction appears as an orange or rust color. In this case, the test result is considered "positive".

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.

The most commonly used syphilis tests screen for an antibody to the syphilis organism. Lupus patients sometimes have a very similar antibody. This similar antibody, the antiphospholipid antibody (aPL), can cause an incorrect positive result on a syphilis test. If the doctor suspects that the patient may not really have syphilis, he may choose to then run a different, more complicated and expensive test that checks specifically for the syphilis organism.

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.

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

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.

This flashing pattern indicates you do not have the AV cable in the rear of your Xbox connected properly, shut off your Xbox, reconnect it and try again.

A. Blue-green water could be an indicator of high copper levels. To discuss the problem, first contact your water supplier. After talking to your supplier, you may also want to contact your local DEQ regional office for more information.

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.

Means that the crossroad has a flashing red, but that the signal goes into normal operation if a car triggers a sensor on the crossroad by waiting a given amount of time. Flashing green/red resumes soon after. (These have likely been removed from the state.) Same as DE's, but only found at crosswalks, and triggered by a button pushed by pedestrians. May be located at a side road or crossroad with a stop sign so the cross traffic can take advantage of the red time on the main road.

If your first HIV test is negative, it means you had no detectable HIV antibodies at the time you were tested. However, if you were only recently exposed to the virus, your result may be negative even though you may be infected. A negative result does not mean your partner is negative or that you will not become infected in the future if you are exposed to the virus.

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.

Lack of a test line - a "negative result" - means that, in the sample taken, Stachybotrys chartarum and Aspergillus niger molds are not detectable within the limits of this test. You may have them in lower concentrations, in other locations, or may have other molds present in varying amounts. In any case, you should clean up the suspected area (or have it cleaned up) and be sure to fix any moisture problems. All molds can gradually destroy the things they grow on.
