Be prepared for your VISIT

Prepare for your visit

Your Appointment cannot be performed earlier than was scheduled, and late appointments may be canceled to avoid a lapse into another client's appointment time.

1.  Arrive on time  

2.  Bring your ID  

Please bring a valid state or federal ID.  In legal DNA testing, a Hospital or Live Birth Certificiate is needed.  

3.  Payment Due  

Your cost is due before services are rendered.  Paramex accepts cash, credit, and debit.

No company or personal checks.  You will be asked to indicate method of payment when making your appointment.  Lawyers, firms, cities, counties, and tribal organizations can set up accounts for multiple client testing, but not for single use.    

4.  Health History  

You will be asked two important health questions.  1. Have you had a recent bone marrow transplant?  2. Have you had a recent blood transfusion?

5.  Restrictions

We will be swabbing up to four sterile cotton swabs on the inside of your cheeks to gather the needed DNA.  Because the collected DNA is in your mouth, to avoid cross contamination, we would ask that you refrain from the following before arriving: NO sharing food or drinks, kissing, breast feeding, or bottle feeding with breast milk.  These activities can leave traces of another's DNA in your mouth causing cross contamination of the collected DNA. It would be best to refrain from these activities for 1 hour prior to your appointments. Eating prior to your appointment is not recommended, but if you do, please drink water and not soda/coffee to be certain your mouth is clean before arriving.  Babies may eat formula and baby food.

6.  Who can come  

We recommend that only the child's guardians, the mother, the children to be tested, and the alleged father come to the appointment.  If additional family or friends arrive, they will not be permitted into the exam room with you unless they are infants.  Our waiting room is often filled with other clients and we ask that visitors of appointments remain at home or in their car.  Your appointment will move quickly.  

Frequently asked questions


1.  Is the collection process safe for newborns?  

Perfectly safe.  They often cry because they confuse the swab as meal time and get very frustrated.


The standard sample for a paternity test is a cheek swab (also called buccal swab), which is a long cotton swab that is rubbed inside the inner cheek lining of a person’s mouth. Typically, four swabs are collected from each tested party. 

3.  What are the risks if I get a prenatal blood draw for our DNA test?    

There are no known medical risks for a standard blood draw.  There is very little blood being taken and we expect the only side effect will be a band aide mark on your arm.  Please be certain to let the phlebotomist know if you have previous history of fainting during blood draws.  Blood draws are required for all Prenatal DNA testing.  Cheek Swabs will not supply the lab with the child's DNA.   

4.  How do we know when the results are available?   

We know you are anxious to get your results and we don't mind you calling and checking on the availability.  We do promise to contact you as soon as we have your results available.  When you arrive for your appointment we will settle terms of result delivery.  The results can be picked up in person upon the submission of a photo ID, faxed, or made available on our website with a username and login for a Paramex My Account.  Internet logins receive email notification when results are available.     

5.  What can we expect to see on the results?  

The results are not as basic as a Yes or No he is the father.  You will typically see a 99.99% or 0% probability of paternity.  This is your indicator.  You are always welcome to ask questions if you need explanation.  

6.  Exactly where and how is our DNA being tested? 

Our results come with the guarantee of quality and are delivered with speed, convenience and most importantly, accuracy through Alliance DNA.  Our results routinely provide a probability of paternity of either 99.99% or 0%. Whether you just need to know or will need results that can be used in a legal matter, Alliance DNA has you covered.

Buccal swabs and blood samples provide results with the same degree of accuracy. But, since buccal swabs are easy and painless to collect, they are used in the majority of DNA paternity tests.

2.  Are buccal swabs as accurate as blood samples?
