A fair test is important so you can get accurate and unbiased results.
If you do not have a control,then you cannot compare your test results.
You can order test online and get your results without anything added to your permanent medical record. Most places seem to be discreet and can have your results within a couple days.
It is important because you can't know if your results are wrong or right.
Record results accurately and honestly. Do the test again to see if you have comparable results, Share and exchange results with others who are involved in the same work, Don't be surprised by results which you hadn't forecast.
So scientists can learn from their mistakes and they can look back on that information in a similar test.
No, it would be unethical and, in the US, illegal to give your best friend information about test results in her husband's medical record unless he had given you express written permission to do so.
Sometimes you can forget what the results of your first test was. It's always good to repeat an experiment more than once, so you can be sure that your tests worked correctly. And, because you should be repeating the tests, you'll want to record the results each time, so you can compare them when you're finished. That way, if something goes wrong, the results will show in which test it went wrong. Plus, if you're doing something for a class, I'll bet you anything that the teacher/professor will want it written down somewhere. Hope this helps!
The results of your certification test are usually mailed to you with a month or two of taking the test. If you don't receive your results you should contact the company that administered the test.

The results of a test
If a nurse does a TB test on 150 individuals and three days later "reads" the results on the person's forearm, without documenting each result, the nurse would never remember those results. A written record can then be used in different situations to prove 1. the test was done and 2. the results were negative. The same principles apply regardless of the type of test---no documentation means the test was never done, period.
