Whether or not to have genetic testing is an important decision for an individual and family members.
A genetic test can result in a number of multiple options and needed decisions.
DNA testing can provide information that opens up new vistas and opportunities while shutting out others.
The other alternative of not doing the test, brings on an assortment of negatives and positives.
The key to the decision making lies in understanding the options and estimating possible outcomes.
Remember the results of a gene test can have a significant effect on the direction of your lifestyle.
There are two main types of DNA Tests A direct test is done when an inherited disorder is connected with known alterations of the gene.
The test is precise enough to indicate specific presence or absence of gene mutations.
The linkage test allows a prediction to be made about the presence of a mutated gene, even if there is no clue or any indication or information of the presence of the gene.
Linkage tests can often be used in situations in which a direct DNA test cannot be done.
The test can still provide clues or predictions about the nature of genes that are present.
When there is no way to detect the "target" gene directly, a known region of DNA located close to the target gene is used as a marker.
Predictions about the actual state of the nearby target gene can be made, by following the marker which serves as an indicator an indicator in much the same way that flags are attached to alert motorists of pending situations.
Four central factors emerge as central in decisions regarding DNA testing:

• The characteristics of the diseases for which the testing is offered, as well as the state and nature of current treatments and prospects for improved therapies.
  In addition to questions about the nature and severity of the disease, there are some important questions about the range of therapies and services that can be used to deal with it.
  The ease and effectiveness of available treatments are also important to consumers
• The test requirements, including the involvement of family members, the costs of the tests and the expected accuracy of the results along with the duration of the tests.
  Some linkage DNA tests may not be as simple and other decisions and actions that can produce some discomfort, may be required before the actual testing is even begun.
  These additional requirements, can play a part in the decision making.
  
• The age and circumstances of the individual at the time of testing:Prenatal DNA testing can done to obtain genetic information about health and future health of the fetus.
  To parents who decide not have children, DNA testing may appear to be unnecessary.
  There is also much consideration given to the age at which children should be tested.
  
• The new options that may arise, as a result of obtaining test results, and conversely options that may be denied: Often the results of gene testing can bring additional complicated choices.
  

The decision to test can be intensely personal decision.
It has to fit into the landscape of one's life, that can include personal values and interpersonal relationships.
The physical, emotional and financial situations must also be considered when dealing with results.
The decision to do DNA testing can be difficult and should not be done in isolation.
