A mitochondrial DNA maternity test traces the maternal line — but it is not the same as a standard maternity test.

mtDNA is passed unchanged from mother to child through the maternal line. That means it can confirm a shared maternal relationship, but it cannot distinguish a biological mother from a maternal aunt or grandmother.

If you need to confirm maternity, that is a critical difference. We cover how mtDNA works and which test actually confirms a biological mother:

If you've ever ordered a home DNA test and wondered what actually happens to your cheek swab after you mail it back, this article covers the full process.

We walk through each step: how to collect your sample at home, how the lab extracts and analyzes your DNA, what happens during the 2-3 business day lab processing window, and how your results are calculated and delivered to you.

US Diagnostics Center's lab analyzes up to 28 genetic markers using STR analysis, the same method used in clinical and forensic DNA work. More markers mean higher statistical confidence in your result.

If you've ever looked at a paternity test result and wondered what all those loci names and marker numbers mean, here's the explanation.

Modern paternity tests rely on autosomal STR markers — short, repeating DNA sequences found on non-sex chromosomes. Scientists compare these patterns between a child and an alleged father to calculate the probability of a biological relationship.

US Diagnostics Center's lab analyzes up to 28 of these genetic markers — exceeding the widely cited industry standard of 20 or more. That means more data points, higher statistical confidence, and a clearer answer.

Our latest article explains what these markers measure, how the probability calculation works, and what your final report actually tells you.

A lot of people start a paternity test and then wonder if the mother’s DNA can be added later. It can, depending on where you are in the process.

When a mother’s sample is included, the lab runs a trio test. It can strengthen a borderline result or confirm a conclusion that a duo test left uncertain.

To test the mother separately, our Home Maternity Test Kit is $129.

If you've ever held a paternity test result and wondered what all those numbers and loci names actually mean, you're not alone. The science behind modern DNA paternity testing is fascinating — and surprisingly straightforward once someone walks you through it.

At the core of every paternity test are autosomal STR markers: short, repeating sequences of DNA found on your non-sex chromosomes. Scientists compare these patterns between a child and an alleged father to calculate the probability of a biological relationship.

US Diagnostics Center analyzes up to 28 of these genetic markers — more than the industry standard of 20 or more — giving you a result with the highest possible statistical confidence.

Our new article breaks down exactly what these markers measure, how the math works, and what your final probability report really means. Whether you're satisfying personal curiosity or seeking peace of mind, understanding the science helps you trust the result.

If the father is not available for a DNA test, two alternatives often come up: an avuncular test using an aunt or uncle, or a grandparent DNA test. Both can help establish a family connection, but they are tested differently, and the accuracy of each depends on how many relatives participate.

Avuncular tests are typically a bit more flexible — any biological sibling of the father can be tested, on either side. Grandparent tests can pull from either the paternal grandmother, grandfather, or both. Getting both grandparents tested improves accuracy significantly.

Have a family member living abroad and need a DNA test?

Home DNA kits can work across borders. Each person orders their own kit, collects a cheek swab at home, and mails samples back to the lab independently. The lab combines both results into one report.

A few things to know:
- Home kits are for personal knowledge only — results are not court-admissible and will not satisfy immigration requirements.
- Shipping timelines vary by country, so allow extra time.
- Immigration DNA testing requires collection at an AABB-accredited facility. A home swab will not be accepted for those purposes.

Most people who want a legal DNA test do not need a court order to get one.

What determines whether a test is "legal" is how the samples are collected, who provides consent, and whether the lab is accepted by the court or agency reviewing the result.

A court order is mainly needed when a parent or guardian refuses to participate, or when a case is already being handled by a judge or child support agency.

If a custody case or support hearing involves parents in two different states, a legal DNA test can still work — collection happens at separate local sites, and everything ships to the same lab for processing.

This guide explains how multi-state legal DNA testing is coordinated, what the chain of custody process looks like across locations, and what to ask the court or agency before you schedule anything.

A home paternity test answers one question: are these two people biologically related?

It does not screen for genetic diseases, carrier status, or health conditions. Those tests use different panels and different labs.

A lot of people ask whether ordering a paternity test might surface other health information. It won't. The article walks through what the test actually measures and what it doesn't.
