Genetic testing is most often used to

analyze human DNA to determine

whether an individual’s

genetic makeup indicates that he

or she is susceptible to

certain medical conditions during

his or her lifetime.

Genetic Testing in humans can help

determine ancestry, paternity and

whether it is likely that an individual

will develop certain medical conditions. The use of genetic testing aims to aid in early detection,

or disease prevention.

Genetic testing is not just available for use on humans. It can also be used to help discover new animal species, to trace bacteria in

food or even determine

geographic origin. How could genetic

testing be expanded in the future? What are other possible

uses?

It is now possible for individuals to

purchase DNA testing kits online. Most often, they

submit a sample of their DNA by

spitting into a tube and mailing it back

in to be tested. These tests can

cost hundreds to thousands of

dollars.

A Done Deal?A Done Deal?The problem with internet testing kits is

that they are not consistent and offer

give inaccurate results. This can often lead to a

person fearing they will develop a disease in their lifetime that they are not actually

genetically susceptible to

develop.

In some tests, a sample of DNA from the one individual has

yielded different results from two

separate internet

companies.

Genetic Testing is especially helpful in analyzing the DNA of potential parents to

improve in vitro fertilization success

rates. It can also help determine the paternity of an

unborn baby, and whether the baby is at

risk for having birth defects such as Down

Syndrome.

Instead of analyzing fingerprints, it is now

possible for investigators to use genetic testing to

analyze DNA from a crime scene. In this way, unique patterns found in

the DNA of likely suspects can be

compared to the DNA evidence collected at a crime scene. This new

technology helps determine whether

someone is guilty of a crime.

The benefits of genetic

testing continue to

grow as research on

disease prevention

and treatment increase.

By detecting predispositions to

diseases or medical conditions early, patients can

seek counseling and hopefully take steps to prevent, or treat certain

medical conditions.

A huge disadvantage to genetic testing is that

patients are often given devastating news and have no access to a counselor or medical professional to help

them cope. The more widespread genetic testing becomes, the more these

professionals are stretched thin and become less

available. Many experts believe this role will soon fall into the hands of less-than-qualified individuals.

Genetic testing can be very helpful in giving

individuals the opportunity to seek

health care that is both appropriate and timely. Doctors can use genetic testing to try to prevent

and treat diseases as well as develop and implement therapies

and treatments that are specific to a person’s

genetic makeup.

Many people worldwide fear that as genetic

testing becomes more common, employers

might base hiring, firing and promotion decisions

on whether an individual’s DNA

indicates that they are susceptible to disease. If an employer has access

to genetic testing results, is this an abuse

of power or an infringement of human

rights?

In addition to fears that employers will

abuse genetic testing results in their

decisions, many fear that insurance

companies will do the same. For

example, insurance companies could

charge higher premiums to those at

high risk, or deny health insurance

altogether.
