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.

It could mean that your urine was more concentrated today causing the slightly darker test line. It could also mean that your surge is starting. It might be a good idea to start testing twice a day if you have this occur.

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.

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.

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.

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 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.

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.

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

NO, in this instance the control line did not show up, therefore the test is invalid. For a positive test, only the control line will be visible. Check the cross-reactant guide under the heading of METHAMPHETAMINE and look for the possible cross-reactant drug. Pseudoephedrine is listed as a possible cross-reactant for Methamphetamine. Retest the person 4-5 days after they have not taken the medication.

When a QED? test result is positive, a dark purple color bar forms within the measurement scale. This color is distinctly darker than the pink or orange color seen as the sample fills the device. The color bar on a positive test -- the same color seen in the QA Spot? -- develops in 2 minutes for the A150 test, in 5 minutes for the A350.

You will always see a control line but if the test line shows up very faint pink or purple within the 10 minute cutoff time, you should assume you are pregnant. You should contact your doctor for further testing right away. You can also re-test in two days and you will probably see a darker line.

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.

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. 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.

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.
