A "false positive" occurs when an initial tests indicates that a person does have WNV or EEE, but a later, more specific tests indicates that the person does not actually have the infection. While it is important for the Maine CDC to get an accurate picture of where people are being infected in order to focus prevention and control efforts, the result does not have a great impact on the individual person. There is no specific treatment that the person would receive due to WNV or EEE.

A false positive hearing screening test result is when a baby does not have a hearing loss but the newborn does not pass the hearing screening. Hearing screening tests are not meant to diagnose hearing loss in infants. Instead, they are meant to find all infants that might have a hearing loss. Because they are not a diagnostic test, hearing screening tests sometimes misidentify infants as having a hearing loss.

Testing positive for HIV means that you now carry the virus that causes AIDS. It does not mean that you have AIDS, nor does it mean that you will die as a result of the virus. Although there is no cure for AIDS, many opportunistic infections that make people sick can be controlled, prevented or eliminated. This has substantially increased the longevity and quality of life for people living with 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.

It is possible to get a false positive test result. This happens when a doctor or laboratory has not performed a confirmatory antibody test before giving people their results. When a person has an antibody test, the lab usually runs two different kinds of tests. One is called an EIA test which is highly sensitive. It can sometimes overreact, so a positive result with the EIA is usually followed up with a RIBA test which is a sophisticated, highly-specific, antibody test.

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.

A positive antibody test could mean one of two things. It could mean that a person is infected with hepatitis C and is a chronic carrier. Or, it could mean that the person was infected with hepatits C but has cleared it from his or her body. An antibody test cannot tell anyone which of those two categories applies. Once infected, you will always have hepatitis C antibodies, and therefore will always test positive on a hepatitis C screening test.

No, even though a gene mutation may be present, you are not at 100% risk for developing cancer. An individual with a BRCA1 and/or BRCA2 alteration is more likely to develop cancer than an individual without an alteration. However, not every individual who has a BRCA1 and/or BRCA2 alteration will develop cancer, because genes are not the only factor affecting cancer risk.

Tests are very accurate but not 100 percent accurate. Usually samples are divided so if an initial test is positive a confirmation test can be conducted. Federal guidelines are in place to ensure accuracy and fairness in drug testing programs.

of the world’s population tests positive for the Tuberculosis antibody. This means at some point in their lifetime they have come in contact with Tuberculosis. A positive skin test and a negative chest x-ray means you have Latent Tuberculosis Infection (LTBI). If you have LTBI you are NOT contagious and CANNOT pass TB to others. However, you have a 15% chance of developing active TB during your lifetime. Medications are available to help prevent active TB in persons with LTBI.

Pap tests are not always 100 percent correct. False positive and false negative results can happen. This can be upsetting and confusing. A false positive Pap test is when a woman is told she has abnormal cervical cells, but the cells are really normal. If your doctor says your Pap results were a false positive, there is no problem. A false negative Pap test is when a woman is told her cells are normal, but in fact, there is a problem with the cervical cells that was missed.

Getting tested for Tuberculosis is very important, especially if you believe you may have been exposed to Tuberculosis. However, there are times when the Tuberculosis skin test produces a false-positive result. Find out what this means and what you should do about it. My husband was exposed to Tuberculosis when someone with Tuberculosis spit on him. He and I both tested positive..

Yes, a false positive test means the test looks as if it is positive, but it is really negative. This happens more often in people who have a low risk for the disease. It is important to confirm the test result a second time.

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.

A false positive is a licit message interpreted by an antispam solution as being a spam. The rate of false-positive is the most important criterion to qualify an antispam solution. This is why ALTOSPAM was thought from its design so as to minimize at most the rate of false-positive.

Some women have a fade-in pattern where the test will get darker for a day or two before the positive result. This generally isn't anything to worry about, and may have the benefit of a bit of advanced noticed. If you find you have a fade-in pattern, you should begin having intercourse when the fade-in pattern starts.

A positive test indicates that there may be bleeding present in the gastrointestinal tract. Polyps, hemorrhoids, rectal fissures, or even stomach ulcers can cause bleeding that would give a positive result. The positive test result may or may not be related to cancer, so it is important to see a physician as soon as possible to determine what is causing the bleeding. Some studies suggest that only 5-10% of those with a positive test result will be diagnosed as having cancer.

A positive test line means you have Stachybotrys chartarum or Aspergillus niger at the sample location, at levels detectable with this test. Although there are as yet no federal or state limits on mold or mold spores, your risk of exposure to these molds and their potential for producing harmful toxins will be greatly reduced by removing them.

Occasionally, a person will get a positive (+) blood test to a disease which he or she does not have. Science has a name for this--"biological false positive". This is why it is so important that a positive (+) HIV test be followed by more HIV tests by a doctor to confirm whether the person is infected or not.

The tests may read false positive (suggesting a person has Lyme disease when actually he does not). Since the tests measure antibodies, it is possible that the patient has antibodies directed against a different organism which previously infected him. If these antibodies are similar to the Lyme antibody, they may give a positive reaction in the lab test, even though they are not Lyme antibodies.

A positive HIV test result means that you are infected with HIV, the virus that causes AIDS. Being infected with HIV does not mean that you have AIDS right now. However, if left untreated, HIV infection damages a person's immune system and can progress to AIDS.

If someone is referred to as HIV+ (positive) , it simply means that the doctor has diagnosed some amount of HIV in your body, however if you are HIV+ it does not necessarily means you have AIDS, you can only have AIDS when the amount of HIV in you gets to a certain level.
