A false positive test is a result that indicates that a person has a disease or condition when they actually do not. This error can occur in many tests. Some are more severe and may have serious health consequences, or even cause death.
False negative results can also happen. False negatives are a little less serious but can still result in dangerous results. For example, if a lab doesn't properly handle a blood sample, it can result in a false negative for tuberculosis. The problem is that the blood sample was not properly drawn, processed or analyzed.
Definition of False Positivity:
False positives are when a laboratory test shows that someone has an illness when they do. This can happen because of errors made in getting the blood sample, or processing it. But sometimes there are other reasons.
The false-positive Rate
A false-positive rate is the percentage of medical tests that show a condition when there really isn't one. This rate can change depending on the type of test performed and what follow-up tests were done following a doctor’s order.
As an example, a breast cancer test has a false positive rate of 8 percent. A test can identify breast cancer in one woman out of 1000.
This is usually a bad test result that will not be accepted. This type of test result is especially dangerous in medical tests, as a patient may not receive the appropriate treatment and could even spread disease to others.
What is a False-positive?
The underlying idea is that any testing method has a chance of giving a false-positive result. The test may be inaccurate, the method of testing flawed, or even the specimen under test not accurate.
The mistake is often made by doctors or scientists. This could be due to an issue with the lab itself or with a test, or it could be that they don't follow up properly with patients when their test results are back.
This mistake could lead to a result that neither the doctor nor the patient want. You may want a COVID negative result to know that you are not infected.
What is a False negative?
A negative outcome is what a scientist or doctor wants to see. It is because a positive result indicates there is not a disease and the person doesn't need medication.
The false-negative rates is the percentage when a medical test shows that there is a problem, but it actually doesn't. This rate varies depending on the type and frequency used in the medical tests, but is typically lower than false-positive rates. The primary reason for this is doctors do NOT want to waste resources and time by treating unwell patients.

The first system is a more traditional system that gives patients little choice about who they see for treatment. They might go to hospital A only if they require an operation. Otherwise, they may as well not bother since there isn't any other option.
This second system is fee-for service. Doctors make money based on how many drugs, tests and operations they perform. If you don't pay them enough, they won't do any extra work, and you'll pay twice as much.
The third system pays doctors according to the amount they spend on care, not by how many procedures performed. This encourages doctors use of less expensive treatments, such as talking therapies, instead of surgical procedures.
