Genetic Screening Test

All you need to know about Genetic Screening Test

INTRODUCTION ❏ A medical test that helps to identify the changes in chromosomes, genes and proteins is generally known as a genetic screening test. ❏ There are several methods which can be used for the genetic screening test in Dubai. ❏ It includes molecular genetic tests or gene tests, chromosomal genetic tests and biochemical genetics tests. ❏ Available types of genetic screening tests in Dubai includes Newborn screening, Diagnostic testing, Carrier testing, Prenatal testing, Preimplantation testing, Predictive and presymptomatic testing and Forensic testing.



Newborn Screening ❏ This test is done just after birth to identify genetic disorders that can be treated early in life. ❏ A newborn screening test is performed with blood tests to check for the rare genetic, hormone-related and metabolic conditions that can cause serious health problems.

Carrier Testing ❏ Carrier testing is usually performed to identify people who carry one copy of a gene mutation that is present in two copies that cause a genetic disorder. ❏ These types of tests are preferred in individuals who have a family history of the genetic disorder. ❏ Also, this test helps to identify the people who belong to certain ethnic groups who have an increased risk of genetic conditions.



Prenatal testing ❏ This type of test is offered during the time of pregnancy and is used to detect changes in foetus genes or chromosomes before birth. ❏ But with this test, we cannot identify all possible inherited disorders and birth defects.

Diagnostic Testing ❏ This test is used to identify special genetic disorders or chromosomal conditions. ❏ This type of test can be performed before birth or at any time during a person’s life. ❏ With the result of diagnostic testing, a person can decide about his health care and management of the disorder.



Forensic Testing ❏ It uses DNA sequences to identify an individual mainly for legal purposes. ❏ This isn't used to detect gene mutations associated with the disease.

CONCLUSION ❏ If the result of the genetic screening test is positive, then it means there is a change in the particular gene or chromosome. ❏ Also, hereditary diseases can be identified easily through the genetic screening test. If the result of the genetic screening test is negative, it indicates that there is no change in the genetic condition. ❏ Genetic screening tests in Dubai offer several benefits whether the result is positive or negative. ❏ Preimplantation testing which is also known as preimplantation genetic diagnosis, predictive and presymptomatic testing are also certain other types of tests which include in the genetic screening tests.
