Legal Question in Criminal Law in Georgia

No one here knows how you are related to the case, what information you have provided, who asked you to take the test, or any other important details about the case. Therefore, no one should tell you whether or not to take the test and you should not base your decision on that. If you are the victim, you need to have a lawyer anyway and that is the person who advises you on these matters.

You haven't told us if you are accused, the victim, or a witness, so your question is unanswerable. If you are the accused, you need to get off the computer, and on the phone, and make an appointment with the best criminal lawyer you can find, as you could spend most of your life in jail.
