Screening

Carrier Screening
Carrier screening is a type of genetic testing performed on people who display no symptoms for a genetic disorder but may be at risk for passing it on to their children.

genetic screening
Testing a population to identify individuals at risk for having a specific genetic disorder or having a child with the disorder.

Screening for new repair-deficient mutants:
To date we have screened approximately 12,100 of 12,500 available lines of EMS induced mutations on the 2nd and 3rd chromosomes from the Zuker collection.

Screening: a test done on healthy people to detect tumors before they become apparent. A mammogram is a screening test.
Diagnosis: the confirmation of the cancerous nature of a lump.

Screening, Genetic Tests, and Counseling
Early diagnosis of cancer greatly increases survival; therefore, regular exams for cancer can help to prevent deaths from cancer.

Screening by hybridization involves spreading the mixture of bacteria out on a dozen or so agar plates to grow several ten thousand isolated colonies.

genetic screening The use of a number of mutant forms of a species to test for a specific type of change or deficit, as with respect to biological clocks.

Genetic screening is the routine testing of individuals for specific genotypes. Newborns in U.S. hospitals are screened for PKU.
PKU women must resume the diet several months before conception ...

Diabetes screening is recommended for many types of people at various stages of life or with several different risk factors.

Genetic screening -- testing groups of individuals to identify defective genes capable of causing hereditary conditions. Genetic variation -- a phenotypic variance of a trait in a population attributed to genetic heterogeneity.

Immunological screening
The use of an antibody to detect a polypeptide encoded by a cloned gene.
Immunoassay
An immunological test to quantitate a particular protein using a antibody that binds specifically to the protein.

presymptomatic screening Testing to detect genetic disorders that only become apparent later in life. The tests are done before the condition actually appears, such as with Huntington disease.

Origin: Screened; Screening.
1. Anything that separates or cuts off inconvience, injury, or danger; that which shelters or conceals from view; a shield or protection; as, a fire screen. Your leavy screens throw down.

Filamentous bacteriophages are used to produce single-stranded DNA for sequencing or in vitro mutagenesis (eg. M13), and as vectors for Phage display expression screening systems ...

Therefore, several years ago, the State of California implemented a simple blood screening called XMSAFP, (Expanded Maternal Serum Alphafetoprotein) done between 15 and 20 weeks gestation to detect aneuploidies and NTDs.

Most infected individuals have either received blood transfusions prior to 1990 (when screening of the blood supply for the Hepatitis C virus began) or have used intravenous drugs.

Genetic testing (o r genetic screening): A technique used to determine whether a person or organism has a certain gene.
Genetics: The study of the patterns of inheritance of specific traits.

Arrayed libraries of clones can be used for many applications, including screening for a specific gene or genomic region of interest as well as for physical mapping.
