With blood donors, screening involves analyzing their blood for certain diseases (such as HCV, HBV, AIDS) before accepting it.
Screening is the process of early diagnosis of a disease, i.e. identification of disease or risk factors for the disease in its pre-symptomatic or pre-clinical stage. There are several well-known mass screening programs, e.g. cervical cancer screening (Pap smear). Screening is useful when diagnosis of a disease earlier than it would usually have been detected improves the outcome.
Carrying out of a test or tests, examination(s) or procedure(s) in order to expose undetected abnormalities, unrecognized (incipient) diseases, or defects: examples are mass X-rays and cervical smears. Pharmacological or toxicological screening consists of a specified set of procedures to which a series of compounds is subjected to characterize pharmacological and toxicological properties and to establish dose-effect and dose-response relationships.
The testing of an apparently healthy group of people to separate those who are likely to have a disease from those who probably don't; e.g. with a Pap smear or mammogram. Screening must be followed up with more complicated diagnostic testing to confirm that the disease is truly present.
In drug discovery testing large numbers of compounds in order to identify those with particular characteristics.
Examining and/or testing a large number of people who have no symptoms of a particular disease, to identify anyone who may have that disease. This enables the disease to be treated at an early stage, when cure is more likely. Examples include Pap tests to detect precancerous changes of the cervix, and mammography, to screen women for early breast cancers.
evaluating populations of people to diagnose disease early
(-) A process for detecting disease before symptoms have occurred by applying tests, examinations or other procedures rapidly.
Looking at large numbers of people in the hope of detecting some disorder. In dermatology, screening is usually used to detect skin cancer.
automated or semi-automated testing of a large number of compounds in in vitro assays such as ligand-binding assays or cell-based assays.

Checking for signs of disease in a person who has no symptoms.
Test to separate patients with tumors from those without tumors. See PSA.
a test or scan which provides a risk factor of the foetus having a genetic or developmental condition, for example serum tests or ultrasound. Screening tests do not provide a conclusive diagnosis, and further tests may be required.
The search for disease in people who are without symptoms.
Tests that sort out apparently well persons who probably have a disease from those who probably do not. If positive, they would be referred to a physician for diagnosis.
The routine search for unsuspected disease (or medical investigation which does not arise from the patient's request for advice for a specific complaint)
A test to identify compounds with potential therapeutic activity.
Testing of a large number of individuals designed to identify those with a particular genetic trait, characteristic, or biological condition.
Identifies people without symptoms who have polyps or CRC.
The search for disease, such as cancer, in individuals without known symptoms. Screening may refer to coordinated mass programs in large populations.
is when healthy children and adults are tested to see if they are likely to develop a condition. Screening tests don't generally confirm that a person has a disease - they are not diagnostic tests. Usually a person will not feel ill from these conditions in any way at the time when they're screened. Screening allows diseases to be identified early, before any signs of illness. This means people can be treated quickly and hopefully avoid getting seriously ill. Screening can happen at different stages and for different conditions. Newborn screening in this country includes tests for phenylketonuria (PKU), congenital hypothyroidism (CHT), cystic fibrosis (CF) and sickle cell disorders.
Testing all or a representative sample of the herd for one or more diseases.
The search for disease, such as cancer, in people without symptoms. For example, screening tests for early detection of colorectal cancer include fecal occult blood test, flexible sigmoidoscopy, colonoscopy, and double contrast barium enema.
Dorland's Illustrated Medical Dictionary defines this as interventions "performed for the early detection of disease or disease precursors in apparently well individuals so that health care can be provided early in the disease or before the disease becomes manifest." (i.e., screening for prostate cancer)
Using tests or other methods of diagnosis to figure out whether or not a particular condition is present in a patient.
A population-based exercise that seeks to prevent cancer or detect it at an early and curative stage, thereby reducing the incidence of cancer-related death or morbidity within the screened community.
refers to a test that can be done to detect cancer as early as possible when it is most treatable.
The process of testing children to determine whether there is any lead in their blood. There are two methods of screening children: the venous method is the most accurate way of measuring lead in blood; the fingerstick method is the easiest way to screen young children, but it is potentially less accurate and because it is prone to sample contamination problems. Any fingerstick that reveals a blood lead level above 10µg/dL must be confirmed by a venous test.
Examinations aimed at detecting medical conditions early in their course or before they become symptomatic, often with the purpose of implementing treatment that will prevent or ameliorate the problem.
Testing for diseases such as cancer in individuals without known symptoms. The term may refer to an individual screening or a coordinated mass program designed to test a large population.
Testing the general population to see if a particular disease can be picked up early - usually before that person has noticed any symptoms. Can only be done if there is a reliable and simple test for the disease, as with the cervical smear test or mammogram.
The testing of an otherwise healthy person in order to diagnose disorders at an early stage.
checking for disease when there are no symptoms.
The process of identifying a developmental delay in infants and children by administering a series of health, hearing, vision, and behavior tests.
Testing people for very early signs of a particular disease - usually before they have any symptoms. Can only be done if there is a reliable and simple test for the disease, such as the cervical smear test or mammogram.
Conducting examinations or tests to detect diseases before symptoms are present. Screening allows for detection of diseases in their early, most treatable stages. In the case of colon cancer, the removal of precancerous polyps found during screening can actually prevent disease.
examination of a group of usually asymptomatic individuals to detect those with a high probability of having a given disease.
when a test is done on people without symptoms who are at risk of developing a certain disease. Screening tests predict the likelihood of someone having or developing a particular disease. The Pap smear is a screening procedure to look for changes that might lead to cancer of the cervix. It is up to 90 per cent accurate and the best way to prevent squamous cancer of the cervix.
Using tests to check for a disease in its early stage, when there are no symptoms. For example, mammography is a screening test that can find breast cancer before it can be felt.
Testing designed to identify individuals in a given population who are at higher risk of having or developing a particular disorder, or having a gene mutation for a particular disorder Related Terms: diagnostic testing ; prenatal diagnosis
Screening is a way of looking for early signs of cancer, or for body changes that might develop into cancer if left untreated. See screening section.
Mass examination of the population to detect the existence of a particular disease.
The process of testing children to determine if they have elevated blood-lead levels.
looking for evidence of a particular disease such as cancer in persons with no symptoms of disease.
The search for disease, such as cancer, in people without symptoms. For example, screening measures for breast cancer include mammography and clinical breast exams.
the search for disease, such as cancer, in people without symptoms. For example, screening measures for prostate cancer include digital rectal examination and the PSA blood test. Screening may refer to coordinated programs in large populations.

when a test is done on all people at risk of developing a certain disease, even if they have no symptoms. Screening tests can predict the likelihood of someone having or developing a particular disease.
Testing for signs of a disease. A positive screening test is NOT the same as a diagnosis of a disease. Screening tests are often used to identify people who should be examined further.
examination of usually symptom-free individuals to detect those with signs of a given disease.
Large-scale examination to collect information on the onset of certain widespread diseases. It enables early-stage disease identification in groups of apparently healthy people.
