screening
Medtalk The evaluation of an asymptomatic person in a population, to detect an unsuspected disease process not known to exist at the time of evaluation; screening tests measure specific parameters–eg, bp–for HTN, sigmoidoscopy–colorectal CA, imaging–eg, mammography–breast CA or lab parameters–eg, cholesterol–CAD, guaiac-positive stools–colorectal CA or Pap smears of the uterine cervix–cervical CA; screening tests in general have high sensitivities and low specificities, which allows detection of most Pts with a morbid condition, while having the acceptable disadvantage of a high rate of false positivity. See Cancer screening, Colorectal screening, Developmental screening, Drug screening, Forensic drug screening, Genetic screening, Industry screening Microalbuminuria screening, Multiphasic screening, Newborn screening Psychiatry An assessment or evaluation to determine the appropriate services for a client.

Patient discussion about biochemical screening.

Q. Is there a good screening test for aortic abdominal aneurysm? A friend of mine was diagnosed with an aortic abdominal aneurysm. I am afraid i might have this condition too. is there any screening test that is good for me?

A. The answer to your question depends on your age your sex and your history of smoking. 3 years ago when my husband was diagnosed with an aortic abdominal aneurysm our GP said that the screening is good only for males age 65-75 that smoke.
Go to your GP and ask him even if you are not in those criteria, maybe the rules have changed.

Q. What are the screening methods for autism? I have a friend who has an autistic child. My daughter is 5 months old and I was wondering if there are any screening methods that help determine autism.

A. The general screening methods for autism are used by parents and pediatricians to evaluate a child’s irregular behavior for his/her age. As a parent, if you see any regression of the child- for instance, he was able to say mom and now he doesn’t say it anymore, or if a child hasn’t started speaking when they should. Those are reasons to go see someone about the possibility of autistic disorder.

Q. How can I lower the damage the cumputer screen is causing my eyes? I work with a computer for long hours every day and so far my sight is still good. Usually after many hours my eyes itch though. All my friends have already ruined their eyes this way and would really like to prevent that... Do you know how?

A. When people hardly concentrate on monitors, used to blink a little. Try to use neutral eyedops. Use only TFT monitors. Another good ways has written above :)
