DNA is the biological blueprint of life. It is a complex molecule present in nearly every cell of the
body and contains the instructions required for growth, development, and maintenance. DNA is
written in a four-letter code of adenine (A), thymine (T), guanine (G) and cytosine (C). Together
these form the human genome, which is around six billion characters long.
DNA is organised into structures called chromosomes. Humans have 46 chromosomes. We inherit 23
from each parent. Genes are segments of DNA located on chromosomes, many of
which encode proteins that influence physical traits, biological processes, and disease
susceptibility.
Genetic testing can be clinically valuable across many areas of health, including earlier
screening and personalised medical care. At iGenetx, we see genetics as a lifelong resource
that supports informed, proactive health decisions. The first step is a conversation with our
team, who will help you decide whether genetic testing is right for you and which test fits.
Genetic testing involves analysing a person’s genes to identify variations that may influence
health. At iGenetx, our tests are clinically actionable because we focus on genes supported by
strong scientific and medical evidence. All identified genetic variants undergo rigorous
interpretation and secondary review by experienced geneticists to ensure accuracy, clinical
relevance, and reliable reporting
iGenetx offers genetic services for individuals seeking a proactive, personalised approach to their health, as well as for those with symptoms, medical histories, or family backgrounds that warrant genetic investigation. Before you buy, our team will talk it through with you and help you choose the test that fits your question.
Whole Genome Sequencing (WGS) is the most comprehensive form of genetic testing. It
reads the complete DNA sequence: the billions of genetic letters that encode all
human genes. This enables an in-depth evaluation of genetic variants across the entire
genome, providing a long-term resource for personalised healthcare.
Next Generation Sequencing (NGS) refers to advanced technologies that allow millions of DNA
fragments to be sequenced simultaneously. This has significantly improved accuracy, reduced
turnaround times, and lowered costs, making comprehensive genetic testing accessible for
clinical use.
Whole genome sequencing allows your complete genetic information to be analysed and
securely stored as a lifelong medical resource. This enables healthcare to be personalised
based on your unique biology. As scientific knowledge advances, your genome can be
re-analysed to uncover new clinically relevant insights, supporting preventive and precision
medicine throughout life.
All individuals carry thousands of genetic variants, most of which are benign and contribute to
normal human diversity. Some variants may slightly increase disease risk, while others have
clinical significance and may require medical attention. Interpretation of genetic results should
always be conducted with a qualified genetic counsellor to ensure accurate understanding and
appropriate clinical guidance.
Being a carrier of a genetic variant is common and not inherently harmful. Identifying carrier status is beneficial, as it enables preventive strategies, informed monitoring, and personalised healthcare planning. Early awareness often leads to better outcomes and more effective medical management.
Not necessarily. Humans have two copies of most genes. In recessive conditions, disease develops only when both gene copies are affected. Carriers usually have one normal and one altered copy and do not develop the disease themselves. However, this information is important for family planning, as two carriers of the same condition may have children at risk.
No. Your genetic sequence remains unchanged throughout your life. What evolves is scientific
knowledge. As research progresses, new discoveries may emerge, making your genome a
lifelong resource that can be revisited to inform future healthcare decisions.
The cost of genetic testing depends on the technology used, the amount of DNA analysed, and the level of clinical expertise required for interpretation. Whole genome sequencing provides the most comprehensive and clinically impactful data. At iGenetx, genetic testing is supported by medical oversight and pre- and post-test genetic counselling to translate results into meaningful, personalised action plans.
