The dawn of the DNA test
Back in the 1700s, the best way to determine paternity was by a good
hard look and the child, followed by a good hard look at the father.
Enough coincidences and maybe a relationship could be proposed. A
hundred years later, eye color was discovered to be a paternity
identifier. This theory has had its flaws exposed because of recent DNA
advances. We now know that eye color is determined by at least six
alleles, or genetic markers. Paternity testing has become a lot easier
and affordable over the past few years due to advances in DNA science.
Although an estimated 200,000 DNA tests are conducted each year by
states needing to sort child-support and welfare issues, few people are
willing to conduct their own at-home paternity test. Few people realize
the simplicity and convenience of an at-home paternity test.
How does a home DNA test work?
Paternity testing requires a painless sample from both the child and
possible father. Even without a sample from the mother, DNA paternity
test results are up to 99.9999% accurate–that’s one-in-a-million odds
your results are incorrect. Most companies provide a free home kit for
you to provide the samples and require you to send the kit back to the
laboratory with the accompanying fee.
Because many companies are aware of the discomfort of drawing blood
from a child in order to get a sample, buccal (mouth) swabs are being
accepted as an alternative. By gently massaging the inside of the
child’s mouth, cheek cells are collected. These cells are then sent to
the lab for testing. Labs analyze up to sixteen genetic markers of the
child and match them against the markers of the alleged father. Because
each of us receives half our genetic markers from each parent, the
results of DNA paternity testing are still accurate without the DNA
information of the mother. Most labs will have results in 10 days and
charge about $290 for a basic paternity verification test.
What else can a DNA test do?
DNA kits can also be used to analyze siblingship, establish cousin or
grandparent relationships, determine twin zygosity (i.e. whether twins
are fraternal or identical), identify ancestral origin, verify Native
American decent, assure parents they left the hospital with the right
baby, and most important, provide legal evidence – be prepared to pay a
bit more for legal tests. Legal tests can be used to settle adoption
issues, settle child-support disputes, and provide information for
immigration files.
How to choose a DNA laboratory
- Accreditation is a vital part of choosing a laboratory. Accredited
labs have an annual audit and inspection, undergo internal and external
reviews, and have their equipment calibrated for accuracy. Look for an
ISO and/or AABB certification. Accredited labs will have a good
reputation and near 100% track record for court cases.
- Look for hidden fees. Some companies will charge you for the kit and
then charge you again for the results. Also, double check when you
order your kit that you’re only buying the results you need.
- Ask about privacy. Make sure that your identity and intentions are
kept secure.
Enjoy piece of mind
Be confident that the questions you have can be answered. DNA testing
is safe and stress-free. Find a free kit and an information packet and
you’re on your way to getting the piece of mind that you deserve.
