false-positive result

Thus, in young women, the test would yield many false-positive results.

There can be false-positive results, indicating a problem when the child is actually healthy.

A false-positive result is more and more likely the closer a woman gets to age 40.

Harms are also increased in younger women because they have a higher rate of false-positive results.

Test results can be difficult to interpret because of the false-positive results.

Nine percent of regular screening attendees had at least one false-positive result.

Oral exams have a high number of false-positive results.

And the chance of having false-positive results is higher when you start having mammograms earlier.

The skill of the doctor also can affect the chance of a false-positive result.

A negative result means you are not allergic, but there are sometimes false-positive results.

The test has a poor positive predictive value with false-positive results in as many as 30% of cases.

And every year it gives false-positive results for three million otherwise healthy women who have to undergo the anxiety of further testing.

The triple and quad tests may show a chance of a problem when there isn't one (false-positive result).

Filtering the reagent before use helps to prevent false-positive results.

A false-positive result can cause stress and lead to unnecessary testing (such as an amniocentesis).

The quad test is less likely than the triple test to show a false-positive result.

Stringent quality control are then applied to the raw sequences to minimize false-positive results.

The Eurofetus study also showed a low rate of false-positive results - seeing deformities that do not exist.

False-positive results in some tests can lead to more invasive measures like biopsies, which carry their own risks.

The high rate of false-positive results of these tests in this setting could lead to unnecessary anxiety and/or treatment (170,171).

False-positive results often occur with hematuria testing; blood in the urine is usually caused by conditions other than cancer.

Although HIV tests are very sensitive, they can produce false-positive results.

This test has moderate sensitivity and specificity, and yields many false-positive results.

These are not affected by immunization or most environmental mycobacteria, so they generate fewer false-positive results.

False-positive results when both screening and confirmatory tests are reactive are rare.
