What is the 3X4 Genetics test?
The 3X4 Genetics Test with Blueprint Report is a proprietary nutrigenomic panel that genotypes a defined set of gene variants across biological pathways — including methylation, detoxification, inflammation, oxidative stress, lipid and nutrient metabolism, hormone metabolism, and insulin/glucose handling — from a cheek-swab DNA sample. The accompanying Blueprint Report organises these results into pathway-based summaries with personalised diet, lifestyle, and supplementation guidance. Its purpose is to inform individualised functional and lifestyle interventions rather than to diagnose disease. Within the assessment landscape, this is a personalised-nutrition and functional-genomics tool, not a diagnostic genetic test for inherited disease. The genotype is fixed and need only be tested once, which distinguishes it from the repeatable biochemical markers practitioners use to track current status. The Blueprint Report translates pathway genotypes into actionable recommendations, but the clinical and predictive validity of many individual nutrigenomic associations is still debated, so results are best used to complement — not replace — measured biomarkers and clinical assessment. Because the test reports heritable genetic information, certain variants (such as APOE) can carry broader health and family implications, making informed consent and access to genetic counselling important considerations.
What does the 3X4 Genetics test measure?
Methylation is a one-carbon metabolic process central to DNA regulation, neurotransmitter synthesis, and homocysteine handling, dependent on folate and B12 cofactors. Variants in genes such as MTHFR influence enzyme activity in this pathway. The panel reports the patient's genotype at selected variants rather than a measured metabolite level.
Methylation-pathway genotypes are used in nutrigenomic interpretation to inform personalised nutrition and supplementation guidance, for example regarding folate form and B-vitamin intake. The clinical and predictive significance of many individual variants is debated, so genotype findings are interpreted as one input among many and confirmed functionally (e.g. with homocysteine) rather than treated as diagnostic.
Hepatic detoxification proceeds through Phase I (e.g. cytochrome P450 enzymes) and Phase II (e.g. glutathione-S-transferase, N-acetyltransferase) reactions that modify and conjugate endogenous and exogenous compounds for excretion. Variants in these genes can alter enzyme activity. The panel reports genotype at selected detoxification-related variants.
Detoxification genotypes are used in functional practice to inform lifestyle and nutritional guidance around oxidative load and exposure. Because enzyme activity is also strongly influenced by environment, diet, and other genes, genotype is interpreted as a contextual input rather than a definitive measure of detoxification capacity.
Inflammatory signalling involves cytokine and mediator genes that influence the magnitude and resolution of inflammatory responses. Variants can modulate inflammatory tendency. The panel reports genotype at selected inflammation-related variants rather than an inflammatory marker level.
Inflammation-pathway genotypes inform personalised dietary and lifestyle recommendations aimed at modulating inflammatory load. They are interpreted alongside measured inflammatory markers such as hs-CRP rather than as a direct measure of inflammatory status.
Antioxidant defence depends on enzymes such as superoxide dismutase and the glutathione system that neutralise reactive oxygen species. Variants can influence antioxidant-enzyme activity. The panel reports genotype at selected oxidative-stress-related variants.
Oxidative-stress genotypes are used to inform nutritional guidance around antioxidant intake. As with the other pathways, they are interpreted as a contextual input, since oxidative balance is heavily influenced by lifestyle and environment.
Lipid handling involves genes governing lipoprotein metabolism and cholesterol transport, including APOE. Variants can influence lipid response to diet and cardiovascular risk. The panel reports genotype at selected lipid-metabolism variants.
Lipid-metabolism genotypes inform personalised dietary fat and cardiovascular-risk guidance. Some variants, notably APOE, carry broader health and counselling implications beyond lipids, so their reporting and interpretation require particular care and may warrant genetic counselling.
Variants in genes affecting the absorption, transport, and metabolism of vitamins and micronutrients (such as vitamin D, B vitamins, and others) can influence individual nutrient requirements. The panel reports genotype at selected nutrient-metabolism variants.
Nutrient-metabolism genotypes inform personalised nutrition and supplementation guidance. They are interpreted alongside measured nutrient levels (e.g. serum vitamin D or B12) rather than replacing them, since genotype indicates tendency rather than current status.
Genes influencing the synthesis, metabolism, and clearance of steroid hormones (including oestrogen-metabolising enzymes) can affect hormone balance and detoxification of hormone metabolites. The panel reports genotype at selected hormone-metabolism variants.
Hormone-metabolism genotypes inform personalised guidance relating to hormone balance and metabolism. They are interpreted alongside measured hormone levels and clinical context rather than as a direct measure of hormonal status.
Genes affecting insulin signalling, glucose handling, and energy metabolism can influence metabolic response to diet and tendency toward insulin resistance. The panel reports genotype at selected metabolic variants.
Metabolic-pathway genotypes inform personalised dietary and lifestyle guidance around carbohydrate tolerance and metabolic health. They are interpreted alongside measured metabolic markers such as fasting glucose, insulin, and HbA1c rather than as a measure of current metabolic status.
Why is the 3X4 Genetics test ordered?
- Practitioners building a personalised nutrition and lifestyle programme who want pathway-based genetic context to complement biochemical testing
- Patients seeking individualised guidance on diet, supplementation, and lifestyle informed by their gene variants across metabolic and other pathways
- Functional and integrative assessment where genotype is interpreted alongside measured markers such as lipids, glucose, vitamin D, and homocysteine
- Tailoring of nutritional strategies where a genetic tendency (e.g. in folate or lipid metabolism) helps prioritise interventions
- Patients motivated by a one-time, fixed genetic profile to guide long-term lifestyle decisions
- Practitioners wanting a structured, pathway-organised report to support patient engagement and personalised planning
- Cases where genetic context may help explain an individual's response to diet or supplements, used as one input among several

Collection notes
Collect per kit instructions, avoiding food, drink, smoking, or gum immediately beforehand and following the swabbing technique to obtain adequate cheek-cell DNA. As this is a heritable genetic test, ensure appropriate informed consent and access to genetic counselling, particularly given variants such as APOE.
Specimen requirements
Buccal swab DNA collected with the 3X4 Genetics kit per its instructions. Follow the laboratory's stability, storage, and return requirements. Genotype is stable and the test is performed once.
What can affect 3X4 Genetics results?
Genetic results indicate inherited tendency, not present physiological state. A variant does not confirm that a pathway is currently impaired, so genotype must be interpreted alongside measured biomarkers reflecting actual status.
Pathway function is shaped by diet, lifestyle, environment, and many genes acting together, so a single reported variant has limited deterministic value and effects are probabilistic rather than fixed.
The strength of evidence linking individual variants to traits or outcomes varies widely, and some associations are weak or contested, so interpretive claims should be appropriately bounded.
Adequate cheek-swab DNA depends on correct collection — avoiding food, drink, or contamination immediately beforehand — so poor technique can cause sample failure or the need for recollection.
The test reports only the predefined set of variants on its panel and does not assess the whole genome, so absence of a flagged variant does not exclude other genetic contributors.
As heritable information, results have implications for the individual and relatives, and some variants carry broader health significance, so informed consent and access to genetic counselling are important.
What do 3X4 Genetics results mean?
Elevated
Not applicable in the conventional sense — results are genotypes, not levels. A reported risk-associated or activity-altering variant indicates a tendency within that pathway, interpreted in the Blueprint Report as a prompt for targeted lifestyle or nutritional consideration rather than a diagnosis.
Normal
A wild-type result at a given variant indicates the common genotype at that locus. Because the panel covers only predefined variants and pathway function is polygenic and environment-dependent, a profile without flagged variants does not guarantee optimal pathway function and is interpreted with measured biomarkers.
Reduced
Not applicable — genotype results are not high or low. The absence of a flagged variant indicates the patient does not carry the tested at-risk genotype at that locus, but does not exclude other genetic or non-genetic contributors.
Note: This is a personalised-nutrition genomic tool, not a diagnostic test. Genotype is fixed and indicates tendency, not current status, so it must be interpreted alongside measured biomarkers and clinical context. The clinical validity of many nutrigenomic associations is debated and effects are probabilistic. Certain variants (e.g. APOE) carry broader health and family implications that warrant informed consent and genetic counselling, and the panel assesses only its predefined variants.
