DNA testing can be extremely helpful in determining whether a person is predisposed to develop a specific disease or medical condition. In some instances (but please note, not all cases) they can also pinpoint specific markers on a parentís DNA to see whether it is likely that they are carrying a disease that can be passed on to their child. Genetic predisposition testing looks at DNA indicators that could influence the phenotype (the exterior expression of genes) of a person and make them more inclined to develop a condition in the presence of certain environmental factors. Please note that this test is for informational purposes only and does not replace the advice of a doctor.
If you are worried that you might be likely to develop a specific condition because a parent or other family member had it, the 25 Disease Predisposition test might be able to give you the answer. This test is very thorough and can provide you with results within 4 weeks after the sample is received at our partner laboratory.
Who needs to be tested?
Everyone can benefit from taking this test. Knowing your genetic health is beneficial for both yourself and your family, as it allows you to test for and identify up to 25 different diseases and conditions that affect both men and women alike today. You can determine how great or how small your genetic predisposition to developing certain conditions is so that you can personally take adequate steps to prevent them in the future.
You should be aware that these steps to prevention are not specifically detailed in the test results, this is something that each patient would need to further investigate themselves. Our test simply details your lifetime risk versus the average lifetime risk for a specific condition, as well as how your genetic markers are linked to each condition.
Just some types of conditions the 25 Disease Predisposition test checks for include:
- Cardiovascular conditions, such as aneurism, coronary heart disease and venous thromboembolism
- Ageing conditions, such as rheumatoid arthritis, osteoarthritis and Alzheimerís disease
- General health conditions, such as obesity, migraines and diabetes types 1 and 2
- Cancers such as bladder, breast, lung, prostate, skin, gastric and colorectal cancers
A comprehensive list of the scientific sources used to generate this information will also be included in your test results, as well as a glossary of terms.
How do I take the test?
The DNA test is easy to use and will involve a simple finger prick blood sample being taken. You will prick your finger with a lancet to draw a small drop of blood, which you will then apply to a testing card. You will receive the safety lancet and detailed instructions for taking the test in our test kit. You should ensure that your finger is clean and completely dry before taking the test and ensure that you have clearly labelled your test before placing it in the envelope for processing. Detailed instructions for how to take each test will be included in your test kit.
What genetic predisposition tests are available?
TestDiagnostics offers only one Genetic Predisposition test that tests for up to 25 different health conditions. This is a peace of mind test, which means that it can be taken for personal benefit only and cannot be upheld in a court of law.
How will I get my results?
Disease predisposition testing can be complicated, which means that your results will take longer than some of the other tests we provide on our site Ė up to four weeks and in some cases, possibly five or six weeks.
Your results will be sent to you via secure email once our partner laboratory has processed your completed sample. You need to ensure that you have fully completed all forms and required information included in your test pack so that the laboratory can make the most accurate analysis, in the fastest time possible.
Itís important to note that this is a very detailed test and you can expect to receive a large PDF document containing your results. As each condition is allocated its own page in the report, each patientís report can vary between 30 to 50 or more pages. Although this can appear daunting at first, the report will give you an extremely detailed outlook on any diseases that you may be predisposed to develop later in life. Each condition is listed in detail on individual pages in the report, including illustrative pie charts, tables and diagrams.
Your genetic DNA report
Once our laboratory has analysed your DNA sample, we will send you a personalised disease predisposition report. Within this report you will find each tested condition listed and ranked according to your estimated lifetime risk. Each of these conditions will be further qualified as low risk, medium risk or high risk. Once you have received your disease predisposition report, and if you are concerned about any condition or do not understand the meaning of the report, we advise that you contact a genetic counsellor or speak to your doctor to help you to make sense of the report and help you to understand what positive changes you can make in your life today. We cannot unfortunately suggest a suitable genetic counsellor or doctor for you, this must be your personal choice.
