Preparing for a DNA Test: Steps to Ensure Accurate Results
Preparing for a DNA test is simple, but it's important to follow a few key steps to ensure the DNA collection includes viable DNA. This article covers some of the basic steps and precautions you can take to get results faster and avoid needing to retest.
At Health Street, we prioritize accurate and reliable DNA testing through our AABB Certified labs, offering various non-invasive testing options with swift results. Acquire your DNA testing kit or schedule a DNA test at your closest Health Street collection clinic, and take the first step toward preparing for an informed DNA testing experience.
The Importance of Preparing for a DNA Test
Whether for legal or personal testing, correctly preparing for a DNA will ensure the integrity of the sample is preserved. Improper handling or contamination can lead to inconclusive results.
Can a DNA Test Be Wrong If You Don't Prepare Correctly?
DNA tests can be invalid—but probably in a different way than you imagine. The risk is more about sample contamination leading to inconclusive results rather than false negatives or positives. In other words, the results are highly unlikely to indicate that two people are related when they aren't, but you might have to retest if viable DNA cannot be extracted from the sample.
