Focusing on older L1 family members is likely to increase the rate of false-negative results.

Do not wash before the test, because that may cause a false-negative result.

A false-negative result from a blood test is possible if you have been infected recently.

"We do have a high false-negative rate," he said in a telephone interview.

But the culture often fails to find the virus even when it is present (false-negative results).

Mammography has a false-negative (missed cancer) rate of at least 10 percent.

Estimates are that there will always be a relatively high Pap false-negative rate - at least 10 to 15 percent.

Because of these variations, any system will make false-positive and false-negative errors.

But these tests sometimes give false-positive or false-negative results.

Even a small increase in fluorescent efficiency could reduce background noise and lower the rate of false-negative results.

However, regular screening helps to compensate for false-negative results.

The high false-negative rate probably led to a failure to detect some symbiont transcripts.

"Whereas, with the defendant, who, presumably, has had the disease longer, the chances for a false-negative are smaller."

It is more relevant to optimize with respect to false-positive and false-negative rates.

This is called a false-negative test result.

Half of the cases resulting in payment to the claimant had false-negative mammograms.

Exfoliative cytology has a high number of false-negative results.

One retrospective single-institution study of 22 patients reported a false-negative rate of 11%.

Then there is the question of false-negative findings, a false reassurance that all is well.

This test is not 100% accurate, with a considerable false-negative rate even with repeat testing.

Occasionally, a multiple sleep latency test can result in a false-negative for a narcoleptic.

We use this property to establish experiment-wide false-positive and false-negative rates (Figure 2a).

Therefore they may be undetected by corresponding diagnostic tests and gave a false-negative result for the infection.

A type II error is a false-negative, or the siding with skepticism.

A false-negative Pap test may delay the diagnosis and treatment of a precancerous condition or cancer.

If there are problems, I think they will be in the area of false negatives.

When a disease is rare, false negatives will not be a major problem with the test.

About 39% of the related documents will be rejected; these are the false negatives.

Patients that receive false negatives are unlikely to seek further treatment for their disease.

This approach is good in terms of speed but poor with regard to false negatives and sensitivity.

"But the search for false negatives is difficult, cumbersome and expensive."

Therefore, the number of true positives increase and false negatives decrease.

Similarly, the use of certain substances, such as steroids may lead to false negatives.

But whole new virus-hunting strategies are required to eliminate false negatives.

Skin prick tests are not always accurate and may produce false negatives.

Moreover, we have seen that, at certain times, the tests involve risks because they produce false negatives.

That may be one source of false negatives.

Imaging should not usually be sooner than 24 hours - high background at this time produces false negatives.

This is usually close to 100%, slightly increasing the inference of innocence over a test without false negatives.

At the same time, mammograms also have a rate of missed tumors, or "false negatives."

False negatives produce serious and counter-intuitive problems, especially when the condition being searched for is common.

It is too early to know of any false negatives but these would probably arise only by laboratory or administrative error.

Either test done alone will give false positives or false negatives.

There will always be false negatives - junk mail that manages to sneak through.

The percentage of false negatives generated by a cancer test was therefore of great concern.

It's like getting the first of two expensive tests (with potential false negatives) for a disease you may or may not have.

False negatives occur when people are rejected as a result of selection test failure, but would have performed well on the job anyway.

The classic test may have produced false negatives, because the child's recognition of the dot did not lead to them cleaning it.

The former result is definitive; i.e., the test does not generate false negatives.

The Government argues that such false negatives render the test unreliable."
