How Long Does a Paternity Test Take?
Waiting for answers from a paternity test can feel stressful, especially when legal or personal decisions are involved. Paternity testing is a common service in the U.S., with thousands of tests performed each year for both legal and personal reasons.
But how long does a paternity test take? Today we’re taking a closer look into the paternity test timeframe, what steps are involved in the DNA testing process, and what factors can delay or speed up your results.
The DNA Testing Process Explained
To understand the paternity test timeframe, it helps to know what happens after the samples are collected. There are three main stages to look at:
- Sample collection and packaging
- Lab transport and intake
- DNA testing and analysis
Sample Collection and Packaging
The DNA testing process starts with collecting cells from the inside of the cheek. This is done using a swab that looks like a long cotton swab. The person rubs the swab along the inside of the cheek for about 30 seconds.
Once the sample is dry, it’s sealed in a packet and labeled. Each test must have its own properly marked envelope.
For legal testing, a trained collector must follow a chain-of-custody process. This means they verify the person’s ID, witness the swabbing, and make sure nothing is tampered with before it reaches the lab.
Lab Transport and Intake
After collection, the samples are sent to a lab for processing. This can take a day or two depending on shipping speed and the location of the lab.
Once received, the lab checks to see if the samples are in good condition. If any are broken, missing, or mislabeled, the test might be delayed.
DNA Testing and Analysis
Once the lab accepts the samples, the DNA testing process begins. A technician extracts the DNA from the cells. They then compare the DNA of the child to the alleged father.
The lab uses special machines to check multiple points in the DNA to see if they match. This part of the process can take one to three business days, depending on how busy the lab is and the type of test ordered. Once the testing is complete, the results are reviewed and sent out to the person who requested the test.
How Long Does a Paternity Test Take?
Most people want fast answers once they’ve taken a paternity test. These are the three most common timelines for receiving results:
- At-home paternity tests
- Legal or court-ordered tests
- Expedited testing services
At-Home Paternity Tests
Many people choose at-home tests because they’re simple and private. These kits are available online or in stores. Once the samples are mailed to the lab, results are usually ready in one to three business days.
The paternity test timeframe starts once the lab gets the samples, not when you take them. Delays can happen if shipping is slow or if the samples are damaged.
Legal Or Court-Ordered Tests
Legal paternity tests take slightly longer because they follow stricter rules. There’s a set process for sample collection, ID checks, and secure delivery to the lab.
After the lab receives the samples, results are usually available in two to five business days. This test is often used in child support or custody cases, so accuracy and documentation are a bigger part of the process.
Expedited Testing Services
Some labs offer faster results for an extra fee. This is helpful if you’re in a hurry or need answers quickly for legal or personal reasons.
Expedited services can sometimes deliver results on the same day the lab receives the samples. In other cases, results may be ready by the next day. Not all labs offer this, so it depends on who you use.
Factors Affecting Test Time
While most paternity tests are processed in a few business days, several things can cause delays. Some of these are out of your control, while others depend on how you collect and send the samples.
Understanding these details can help you avoid problems. There are four main things that can affect how long the results take:
- Shipping and delivery times
- Sample quality or condition
- Type of test selected
- Lab schedule and holidays
Shipping and Delivery Times
The paternity test timeframe doesn’t start when you swab your cheek. It starts when the lab gets your samples. If shipping takes several days, the wait for results gets longer.
Using a slower shipping method or mailing your samples over a weekend can add time. Delays may also happen if you live far from the lab or if the package is lost in transit.
Sample Quality or Condition
Poor sample quality can slow things down. If the cheek swabs are not sealed correctly or are touched after collection, the lab might not be able to use them.
Sometimes, people don’t swab long enough, or the sample dries out before it reaches the lab. If there’s a problem, the lab will ask for new samples, which adds more time to the process.
Type Of Test Selected
Some tests take longer than others. Legal paternity tests usually take longer because of the steps involved in verifying identities and keeping a proper record.
At-home tests tend to be faster but may not be accepted in court. Express services are available, but not every lab offers them. If you want faster results, you may have to pay more or contact the lab ahead of time.
Lab Schedule And Holidays
The lab’s workload can also affect the genetic testing duration. If many tests are being processed at once, results might take longer.
Some labs may be closed on holidays or weekends. During these times, your sample may sit for a day or two before testing begins.
Factors Affecting Test Time
