If a person types your web site address, or the URL to any particular page within your web site, directly into their browser's address bar, or if your site is their homepage when they open the browser, there will not be a referral for that visit because the visitor is not coming from someplace prior to hitting your site, they are coming directly to your site. There are also some scripts that can be used to block referral information when a visitor navigates from one web site to another.

Nonreactive indicates that the serum tested does not have detectable antibodies to HIV-1. There are several reasons for this: Person is in the window period immediately after infection when antibodies are not yet being produced. Person is in the final disease stages when the immune system is no longer capable of producing detectable antibody.

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

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.

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.

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.

NO! OptiGen test results are meant to be used in a responsible breeding program. This does not mean that carrier or affected dogs should never be bred. It does mean that carrier and affected dogs with other desirable traits can be bred, but only to a certified, genetically “Normal/Clear" dog in order to prevent the genetic disease. We can't make specific recommendations about how people should handle their dogs.

NO! Most reports of child abuse do not result in children being removed from their families. The first goal is to enable the child to remain safely in higher own home.- If this is not possible, the social worker must remove the child from the home and place him/her in . a foster home. If it is necessary in order to protect the child, the child welfare agency also is authorized to arrange emergency, temporary foster care.

Consult with the Department of Health Services. However, the HUD Guidelines "action levels" for Paint are 0.5% by weight = 5,000 ppm by Atomic Absorption Spectroscopy (AA) or 1.0 mg/cm2 by XRF. Soils: EPA TSCA Section 403 Standard - January 2001 are > 400 ppm Hazardous in play areas. > 1,200 ppm Bare soil yard wide average. California Title 17 "Lead Contaminated Soil" - ? 400 - 1000 ppm Hazardous in bare soil in areas where children play. > 1,000 ppm Hazardous in all other areas.

If you brought in a sample to find out if the sample had mould, then either the sample did with a specific identification of what mould there was or it didn't. If you we did an air sample, you compare the indoor samples to the outdoor samples. If the indoor samples are lower than the outdoor samples, at that moment in time, the air quality was okay. If the indoor samples were higher than the outdoorsat that moment in time, the air quality was degraded.

Inconclusive TP-PA - If Reactive results are seen with both sensitized and unsensitized particles, nonspecific agglutination is indicated. The serum may or may not be reactive for T. palladium. In the TDSHS laboratory, specimens that show (> ?) reactivity with the unsensitized particles are reported as Inconclusive due to nonspecific agglutination and are then tested by the FTA-ABS.

Equivocal TP-PA - Specimens that show low reactivity, defined as either ( 1+) or (?) reactivity with the sensitized particles and (-) reactivity with the unsensitized particles, are repeated on the TP-PA. If the results of the repeat are the same, it is reported as Equivocal and are then tested by the FTA-ABS.
