The DNA Maternal Ancestry test is a mitochondrial DNA test that traces direct maternal lineage. The DNA Paternal Ancestry test analyzes markers on the Y chromosome to determine direct paternal lineage.
Each DNA test requires an individual sample collection, and the reports are delivered separately. The company offers phone consultations and expert Ph.D. consultations for an additional fee.
Review of Genex Diagnostics Reports
Genex Diagnostics does not offer sample reports, so it’s unclear what results you’ll receive. The reports are available on the user’s secure online account. Customers can also request that the report be mailed or emailed to them.
The company claims that the health and wellness reports include explanations about how DNA and health are connected, but they do not offer personalized recommendations to help you address your health issues. Genex only states that physicians can use your results to plan personalized treatment plans.
The Health & Disease reports include an analysis of various health conditions. Each test analyzes genetic markers related to the specific condition. For example, the Cardiovascular Health test examines SNPs related to lipid levels, including cholesterol and triglycerides. The report reveals if you have genetic variants that can affect heart health.
The Diet & Fitness tests focus on traits that are linked to overall well-being, such as fitness and nutrition. For instance, the Nutrition test analyzes how genes affect the absorption and usage of certain vitamins and minerals.
As seen in the screenshot below, the report explains how the body metabolizes different nutrients.
Since the company does not provide sample reports, the extent of the information provided in the reports is unclear. You can download the results as soon as they are available online.
Cost of Genex Diagnostics
Genex Diagnostics’ Relationship tests start at $99. If customers wish to use the results for legal purposes, the cost increases. The company offers professional collection and witnessing services for $50 per person tested.
The Health & Disease tests cost between $149 to $349. The Diet & Fitness test prices vary from $149 to $489. The DNA Maternal and Paternal Ancestry tests cost $119 each. The Behavior & Traits tests are priced at $149.
They may charge extra fees for additional report copies. A 10-minute phone consultation costs $10. The expert Ph.D. consultation costs $400 per hour (minimum of one hour).
Health Recommendations from Genex Diagnostics
As Genex Diagnostics does not provide sample reports on their website, it is unclear the extent of the health recommendations they provide. The only claim they make is that a physician is able to use your results to plan personalized treatment options. If you’re interested in understanding what you can do to address your genetic risks, you might need to look elsewhere.
SNP Analysis vs Polygenic Risk Scores (PRS) vs Advanced PRS
When it comes to understanding genetic risks, the type of analysis used makes all the difference. Most companies, including Genex Diagnostics, rely on SNP analysis, which examines a few individual genetic variants associated with specific traits or conditions. While this approach can provide limited insights, it doesn’t capture the complexity of how multiple genes interact to influence your health.
Polygenic Risk Scores (PRS) represent a major advancement. Instead of focusing on one or two variants, PRS combines the effects of millions of variants across your entire genome to calculate a more accurate prediction of your risk for various health conditions. This allows for a deeper understanding of your unique genetic predispositions.
Advanced PRS, like the one developed by SelfDecode, takes this one step further by adjusting results based on ancestry and integrating additional data, such as symptoms, lab results, and lifestyle factors, to provide the most accurate and actionable health insights available today. This method, validated in peer-reviewed research published in a Nature journal, ensures that your predictions aren’t just broad averages but are fine-tuned to your individual background and biology.
While traditional SNP-based approaches can cost only a few thousand dollars to develop, building an advanced PRS system with multiomic integration like SelfDecode’s requires millions in research and infrastructure, over $25 million, in fact.
The result is a platform capable of analyzing more than 200 million variants, generating highly personalized, science-backed health recommendations that far exceed what basic genetic testing companies like Genex Diagnostics can offer.
Review of Genex Diagnostics Privacy & Data Security
Genex Diagnostics maintains that personal information will only be used to carry out their services. They state that they employ electronic and physical procedures to safeguard the data and prevent it from being wrongly accessed.
The company claims not to disclose personal information to third parties, except if it is required by law. They say users can withdraw their consent to the processing of their personal information at any time.
Genex Diagnostics Reviews
Despite the many years in business, there are not many online Genex Diagnostics reviews available. 7 DNAtestingchoice users rate the paternity test an average of 4 of 5 stars. All reviews revolve around the paternity test and they say the company provides quick and accurate results.
BestDNATestingKits rates the company 4 of 5 stars. They like the wide variety of DNA tests and the simple sample collection but say the test prices are very expensive.
Alternatives to Genex Diagnostics

Genex Diagnostics Review Summary
Genex Diagnostics offers health, wellness, and biological relationship tests. Despite the variety of tests offered, how convenient they are is debatable. Each test requires a separate sample collection. If users wish to get tested for multiple health conditions, they are required to purchase and take several tests.
From their website, you might be left confused about what exactly your report will include. The information provided is vague, and the prices are high. As it is, one health-focused DNA report from Genex Diagnostics can cost up to $349.
If you’re interested in a gene-based approach to your health, an alternative such as SelfDecode is a better option. SelfDecode uses AI and machine learning to analyze up to 200 million genetic variants and gives personalized recommendations based on your DNA. If you want a more holistic approach to health and wellness, SelfDecode is a great place to start, with reports on over 1,500 health topics.
