DNA genetic testing is at its peak, by the start of 2019 twenty six million people had purchased genetic testing kits from different companies, people go crazy about finding out trace percentages of their ancestry. genetics based vacations to places where our ancestors lip but direct-to-consumer genetic testing can go way beyond that it can help us tackle inherited diseases, it can teach us about what diet serves your body best or it can warn you about, how you will react to certain medications it can be a goldmine of medical information that can help you live longer and healthier. In this Article I would like to take you through the experience of genetic testing that goes beyond ancestry and show you what to expect and how to use the information to improve your life.
The collection of our genetic information will point to billion base pairs which is the blueprint of every organism, your cells work based on the instructions they get from that blueprint
Genetic tests usually use a method called genotyping since 99.9% of the human DNA is the same, in every one of us genotyping doesn’t look at all the 3.2 billion base pairs, and it only focuses on a few hundred thousands of them that makes up that 0.1% that differentiate you from others.
step by step explanation about DNA testing
I will explain the process with you step-by-step I want to tell you how dna testing works, what to expect from the results and what to do with the information you get
so first things first, the sampling process for this article is test from a company called Atlas pilot, but genetic tests have a fairly similar sampling process the companies send you a small cube that you need to fill up with a disgusting amount of saliva and even though it sounds easy enough it takes some time the most important thing is that you can’t eat, drink, smoke or even use a chewing gum at least for half an hour before taking a test.
when you are ready, you screw the cap on the container releasing the DNA preserving liquid, you mix the materials and see it since you are dealing with a biological sample you have to do some administrative work and then you can send it back to the lab .waiting is probably the worst part of it, I understand that shipping the package conducting the genetic analysis and uploading the results takes time but in cases like this people tend to be impatient. in this case the person waited for four weeks and luckily the company kept him posted about the progress of his analysis and they also send a survey to assess his general lifestyle habits to get to know him better. He had to respond to questions about his height, weight, diet, workout plan and whether he smoked or not.
They try to obtain every piece of detail about his lifestyle that cannot be mined from a genetic test. When the report of his results finally arrived he certainly wasn’t disappointed, it was available in a nicely designed transparent and very user-friendly online dashboard. However I have to tell you beforehand that different companies use different technologies for analysis and results may finally vary.
The test provided by his DNA showed what kind of medications he have a sensitivity for, he learned that if he ever have to take a medication lowering cholesterol he might get significant side-effects. It’s good to know another test from food to our genetics determine that. he does have a genetic predisposition for obesity therefore he must make sure that he follow this lifestyle he has now forever was learning about his risk for deep vein thrombosis prompted his primary care physician to let him know that if he ever have an injury and must stay in bed for more than a day or so
We have to consider a medication against blood clots now you might ask how many tests he need to take to have a clear picture, the answer can be different depending on what you’re looking for or the answer can be only one while genotyping looks at few hundred thousand base pairs in your DNA. Genome sequencing goes for the whole nine yards and looks at the old 3.2 billion genome sequencing is basically the same method that the human genome project developed but while back then it took 13 years and three billion dollars to do it now it cost less and affordable
whether you are taking the genotyping test or doing original sequencing, its highly recommended to get the assistance of a genetic counselor to put things into perspective and help you interpret complex and at times overwhelming results .it could be a scary experience to know this much about yourself but I also believe that now that we have the technology we shouldn’t bury your heads in the sand, we can change our lifestyle to be in harmony with our genetic code because if we know what dangers lurk in our future we can take steps to limit their risks or prevent it entirely because as the saying goes genetics loads the gun but lifestyle pulls a trigger. The amazing part of this whole DNA testing is that now anyone can order a test package online and in four weeks they can have their personal genome sequence.
