The current polygraph research indicates that when a specific single issue polygraph exam, conducted by a qualified, trained, and experienced polygraph examiner, is properly administered the accuracy rate is between 95% and 98%. This percentage is still higher than other forms of evidence, including psychiatric opinions, suspect identification as provided by victims and witnesses, and fingerprint identification.

Yes. In a multicenter clinical study this test service, using blood from a finger stick obtained by non-medically trained participants, was proven to be greater than 99% accurate compared to a blood sample drawn by a medical professional and tested using current test methods. In this clinical trial approximately 4% of study participants were unable to collect enough sample to begin testing, and an additional 3% were unable to collect enough sample to receive a conclusive result.

The polygraph technique is very accurate, however, it is not infallible. According to the American Polygraph Association, over 250 studies have been conducted over the past twenty five years on the accuracy of polygraph testing. It is estimated that the accuracy of the results is in the range of 90 - 95 %. More recently, research has shown that the accuracy of computerised polygraph testing is 98 %.

The Q.E.D.® test can be used as an accurate screen in place of blood or breath tests. In clinical trials, saliva alcohol levels measured by the Q.E.D.® demonstrated high correlation to blood analyzed by gas chromatography (r=0.98).

Yes. The VAP Test is based on ultracentrifugation, the gold standard for reference lab lipid measurement. The test is processed at Atherotech's CLIA-approved diagnostic laboratory. In addition, Atherotech has the accuracy of the VAP Test confirmed by three highly recognized lipid standardization programs-the American Association of Bioanalysts, the Northwest Lipid Research Laboratories, and the Accutest Proficiency Testing Program.

In laboratory tests, IntelliGender Gender Prediction Test (G.P.T.). has proven up to 90% accurate. Factors which could affect the accuracy include: failing to use first morning's urine, not following instructions provided in the kit and diluted urine from drinking excessive liquid within 3 hours of performing the test.

The OptiGen direct mutation tests are exactly accurate. This means that the test gives clear readings in the laboratory; there is no issue of interpreting what we see. Numerous controls--absolute measures of accuracy--are used with every sample we process. The results for each dog will never change with age and will be the same whenever the same version of the test is repeated.

When the test is conducted by a highly trained and skilled examiner, it is highly unlikely that someone can beat the test or what is known as using counter-measures. All skilled examiners are vigilant about counter-measures and would usually have a finding of inconclusive if he suspects that counter-measures were used by the examinee.

employer can request that an employee take a polygraph test only if certain criteria have been met according to the Employee Polygraph Protection Act of 1988. Regardless of whether or not the employee agrees to take the polygraph test, they will need to fill out a request form which outlines and explains the employee's and employer's rights. Click here to download a copy of that form, which you can fill out online and then print out. We strictly adhere to the EPPA guidelines for your protection.

It's pretty much game over for you unless youre a cool craftsmith like me. Next time, try to avoid getting into that sort of position. Revealing the truth is the easiest and most painful way out. Before you lie, you should be sure you can deal with the moral conflicts that arise. Otherwise, drugs, alcohol, heavy metal music and sex are quick fixes, but really you alone have to deal with it. Lies will get you out of this if youre crafty enough.

Yes and before you schedule your test, you should always tell the examiner what kind of medications you are taking.

Our test is a urine-based test, and according to the manufacturer of this product, it is 99.7% accurate. Other tests may vary in their accuracy.

Home Access® Hepatitis C Check Tests are designed to provide you with a scientific test result that you can trust. Home Access' Hepatitis C Check Tests use the same tests run by doctors and hospitals and is clinically proven to be greater than 99% accurate.

Because we use the latest, state-of-the-art computer hardware and software instead of the old, analog machines, results are about 98-99% accurate (according to research from the American Polygraph Association). All of our examiners participate in continuing education, which also helps ensure high accuracy rates. Many examiners can't or won't purchase the latest equipment due to the high investment costs, as well as the costly and time consuming training that goes along with it.

You can get accurate results from a pregnancy test while you're on the pill. Pregnancy tests work by measuring a specific pregnancy-related hormone — human chorionic gonadotropin (HCG) — in your blood or urine. The active ingredients in birth control pills don't affect how a pregnancy test measures the level of HCG in your system.

New findings from a multi-center study of the accuracy of CT colonography suggest that it can detect about 75 to 85 percent of intermediate and large polyps. It is not as accurate in identifying smaller polyps, which also have the potential to develop in to cancer. Previous studies of CT colonography had shown a very wide range of results.

Our definition of "accuracy" has to do with the detection of the markers used in the laboratory. The OptiGen test for the markers of PRA is exactly accurate. This means that the test gives clear readings in the laboratory; there is no issue of interpreting what we see--no false positive in reading the laboratory result. (A false allele result is not a false positive result.) Numerous controls--absolute measures of accuracy--are used for every sample we process.

A blood test is more accurate, but it depends on the type you get. Many doctors will order a simple qualitative hCG. It only gives a yes or no answer, but doesn't register your HCG levels. If you are early in your pregnancy, and your levels are low, you may get a false negative. A quantitative blood test will measure the exact amount of hCG present. It will detect even the most minimal level.

There are a variety of types of genetic laboratory tests, but the accuracy varies depending upon the test and the type of tissue studied. Generally speaking, genetic laboratory testing is highly accurate.

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.

In independent studies the accuracy of the MiraTes HIV test has been assessed. The accuracy has been found quite comparable with the standard laboratory tests with percentages around 99,5 %. However, as with standard laboratory tests, false positive results do occur. For this test this is 0,3%. When testing in low risk populations, false positives will occur more often in relation to true positives. For this reason it is always necessary to reconfirm positive test results.
