How Long Does a DNA Test Take

If you're asking yourself "How long does a DNA test take?" you're not alone. Many people search for this information every month, and most are looking for the time it takes to get a DNA paternity test. Paternity test results vary, but we can help you know when to expect them.

How Long Does It Take?

How long a DNA test takes depends on a few factors: the laboratory doing the testing, the time it takes for them to receive the DNA sample, and how many other samples they are processing at the same time.

The type of DNA test also has a lot to do with the turnaround time. As you'll read below, a DNA paternity test can take much less time than whole genome sequencing.

How Long Does It Take to Get DNA Paternity Test Results?

Paternity tests take about 2 to 5 days to process once the samples are received by the lab. DNA paternity testing is one that comes along with the question of how long it takes. This process involves collecting a DNA swab from the alleged father and the child, sending the samples to the lab, having the lab process and analyze the samples, and then receiving the results.

Court-Ordered DNA Tests: How Long It Takes

A court-ordered DNA paternity test can take from 2 to 10 business days depending on the laboratory the collection kit was sent to.

Despite the legal implications of DNA testing, it still takes just as long when it comes to the actual testing process. This is why many cases can be delayed as an alleged father and others await results.

Reasons the process could take longer include the lab not being able to process the DNA test kit within the expected timeframe, or the collection kit not including a viable sample. If that is the case, it can take additional weeks to get results, as new samples must be collected and the kit sent again for processing.

The only way to expedite the process for legal purposes is to request that the court put a rush on it, which could lead to faster processing depending on the laboratory.

How Long Does Whole Genome Sequencing Take?

Whole genome sequencing analyzes your entire genome and takes longer than a basic paternity test. Processing typically takes several business days once your sample is received, and most people receive their results within a few weeks from the time they send in their kit.

The process for whole genome sequencing involves several stages. First, it takes time to extract the DNA from the swabs in the kit, purify the DNA, and perform quality control testing to ensure the DNA is of sufficient quality and quantity. The next stage is sequencing the DNA itself, which can take additional weeks. When a laboratory is particularly busy, additional time may be added to the turnaround.

Once the laboratory completes your whole genome sequencing, the raw data is then processed by Sequencing's proprietary bioinformatics system. This step includes additional quality control, comprehensive data processing, and delivery of your raw data to your Sequencing account.

DNA Test Result Analysis and Reports

While waiting a few weeks to receive results from a laboratory may not seem fast, it is the reality of comprehensive DNA testing. Waiting for the results is worth it when you consider all of the information you can get from a whole genome sequencing report.

Health reports from DNA testing companies such as Sequencing, Family Tree DNA, Ancestry, 23andMe, and MyHeritage can be helpful in seeking preventive treatment if they show a family history of genetic conditions. DNA test results can help your doctor check for signs and symptoms of those conditions so that action can be taken as early as possible.

Once a DNA test has been taken for personal or legal reasons, it is possible to have the results analyzed for additional information. Analysis of your DNA data happens quickly through apps in the Partner Marketplace. Simply choose the app that provides the information you are interested in, start the app, and usually within minutes the app will generate a genetic report personalized to your DNA.

DNA Testing for Health and Diagnostics

DNA testing can even be used to help with diagnostics. DNA diagnostics is something that many doctors are using and it has been shown to be effective in identifying treatment options and informing personalized care.
