Carrier testing is a type of genetic testing that is used to determine if a person is a carrier for specific autosomal recessive diseases. [1] This kind of testing is used most often by couples who are considering becoming pregnant to determine the risks of their child inheriting one of these genetic disorders. [2]
Carrier testing is used to identify people who carry one copy of a gene change (also referred to as a variant or mutation) that, when present in two copies, causes a genetic disorder. Carrier testing is typically offered to individuals who are considering pregnancy or are already pregnant, have a family history of a specific genetic disorder ...
Carrier testing can help guide the decisions of couples who are at high risk, e.g.: Both of Jewish descent – Several disorders including Tay–Sachs disease. The organization Dor Yeshorim offers testing in many countries. [citation needed] Both Cypriot – Thalassemia. Testing is fully subsidized and mandated in both jurisdictions on Cyprus.
With regard to genetic testing and information in general, legislation in the United States called the Genetic Information Nondiscrimination Act prohibits group health plans and health insurers from denying coverage to a healthy person or charging that person higher premiums based solely on a genetic predisposition to developing a disease in ...
This type of testing is offered to individuals who have genetic disorder in their family history or to people in ethnic groups with increased risk of certain genetic diseases. If both parents are tested, carrier testing can provide information about a couple's risk of having a child with a genetic disorder. Diagnostic testing: Diagnostic ...
A hereditary carrier (genetic carrier or just carrier), is a person or other organism that has inherited a recessive allele for a genetic trait or mutation but usually does not display that trait or show symptoms of the disease. Carriers are, however, able to pass the allele onto their offspring, who may then express the genetic trait.

Genetic screening including carrier screening, prenatal screening and newborn screening could be done on individuals for early detection of genetic defects. As there are many X-linked genetic diseases, the pathology and mechanism of each varies significantly, there is no clear-cut diagnosis and treatment for all diseases.
