Frequently Asked Questions about Functional Genomic Analysis

FGA (Functional Genomic Analysis) is a comprehensive analytical method that starts from genetic variations, integrating metabolic pathways, nutritional needs, and health manifestations. It focuses not only on 'which genetic loci are present' but also further explains how these loci may affect functions such as methylation, detoxification, inflammation, oxidative stress, neurotransmitters, and nutrient metabolism, providing a reference for subsequent report interpretation and personalized health management. FGA is used for health risk and functional status analysis and does not replace clinical diagnosis, prescription, or emergency treatment.

Ordinary genetic testing often focuses on single disease risks, hereditary traits, or a limited number of loci, with the test results themselves being the primary deliverable. FGA emphasizes a continuous interpretation of 'loci-pathway-function-intervention recommendations': based on a broader range of SNP data, combined with multiple metabolic maps and the relationships between loci, it helps professionals understand potential functional weaknesses and the priority order for nutrition and lifestyle management. The two are not simple substitutes; they differ in applicable purposes, analytical depth, and subsequent service methods.

'260K SNP loci' indicates that the analysis covers approximately 260,000 single nucleotide polymorphism loci. A larger coverage of loci can reduce the one-sidedness caused by focusing only on a few 'star genes' and provides the opportunity to understand functional differences in nutrient metabolism, detoxification, hormonal balance, neurotransmitters, etc., from the combined relationships of multiple genes and pathways. A large number of loci does not mean each locus has the same clinical significance; final judgment still requires comprehensive consideration based on research evidence, algorithm weighting, individual manifestations, and professional interpretation.

NGRI stands for NutriGenetic Research Institute, founded by Mr. Bob Miller in 2015. Its research focus is on the relationship between genetic variations, nutritional metabolic pathways, and health outcomes. The analytical framework, metabolic map associations, and continuously updated algorithm system of the FGA platform are derived from the research accumulation of NGRI. NGRI emphasizes research and method development, while FGA translates these achievements into analytical tools that can be used for testing interpretation and personalized management.

SNP stands for Single Nucleotide Polymorphism, referring to common differences at a specific base position in the DNA sequence within a population. Most SNPs are natural genetic variations and are not equivalent to diseases or harmful mutations; they may affect enzyme activity, nutrient utilization efficiency, or certain physiological pathways, or they may have no clear functional impact. 'Gene mutation' is a broader concept that includes both common variations and rare pathogenic variants that may cause hereditary diseases. Whether they have medical significance requires interpretation according to professional standards.

Functional medicine emphasizes understanding individual health issues from a systemic and root-cause perspective, focusing on the connections between genetics, environment, nutrition, lifestyle, and multiple physiological systems. FGA can provide genetic and metabolic pathway-level references for functional medicine practice, helping professionals more targeted in selecting assessment priorities and management sequences. However, FGA is only one source of information and must still be used in conjunction with medical history, symptoms, signs, laboratory tests, and physician judgment.

The 42 metabolic map categories are used to organize scattered genetic loci into understandable functional networks, typically covering directions such as methylation and one-carbon metabolism, glutathione and detoxification, oxidative stress, inflammation regulation, histamine metabolism, neurotransmitters, mitochondrial energy, lipids and cholesterol, glucose metabolism, vitamin and mineral utilization, hormone metabolism, immune and gut-related functions, among others. Each category is composed of multiple related loci and pathways; a single locus should not be directly equated with a disease conclusion. The specific map names and interpretations are subject to the current version of the FGA report.

After completing the test, you will receive genetic loci and functional pathway analysis results, which can be interpreted by professionals in combination with your personal situation. Key deliverables include noteworthy metabolic maps, potential nutritional needs, functional directions requiring further verification, and reference priorities for lifestyle and personalized nutrition management. The report is not for self-diagnosing diseases or discontinuing medications; if clues related to clinical risks are found, they should be confirmed by a physician in conjunction with medical examinations.

FGA is suitable for adults who wish to systematically understand their own nutritional metabolic characteristics, family health risk background, long-term sub-health manifestations, or need personalized health management references. It can also provide foundational data for professional health management plans. Individuals with acute illnesses, emergencies, or those requiring immediate diagnosis and treatment should not rely on this test to delay medical care. Pregnant or breastfeeding women, minors, individuals undergoing major disease treatment, or those with complex medication situations should first confirm suitability and subsequent interpretation boundaries with their doctor and the testing institution.

The standard process is typically divided into four steps: First, complete consultation and informed consent, and collect oral swabs or other compliant samples as required. Second, deliver the samples to the laboratory according to specifications for quality checks and genotyping. Third, generate the FGA report, with professionals explaining key metabolic maps and loci in combination with personal data. Fourth, develop nutrition, lifestyle, or further examination recommendations based on the interpretation results, and conduct periodic follow-ups as needed. Specific sample types, logistics, and service content are subject to the plan confirmed at the time of appointment.

The reporting cycle starts from when the laboratory confirms receipt of a qualified sample. The actual time may be affected by sample quality, logistics, laboratory batch processing, and report interpretation scheduling. Staff will explain the expected cycle based on the current service batch at the time of appointment. If the sample fails quality checks, re-sampling may be required, and the timeline will be extended accordingly. After receiving the results, it is recommended to schedule professional interpretation simultaneously, rather than making judgments solely based on colors or single loci in the report.

Whether fasting is required and whether blood is drawn depends on the sample type used for this service. If using oral swabs or saliva samples, blood drawing is typically not required. However, before sampling, you should temporarily avoid eating, drinking, smoking, chewing gum, or brushing your teeth as per the instructions to reduce sample contamination. If the service plan includes blood biochemical tests, you must follow the fasting and blood collection requirements of the corresponding medical institution. Please refer to the sampling kit instructions and staff notifications for specific guidance.

You can consult, schedule appointments, collect samples, and receive report interpretations through the project's service channels within China. The actual available testing items, sample shipping methods, partner laboratories, and service cities may change according to compliance requirements and operational arrangements. Before scheduling, you will be informed of the current process, informed consent, sample handling, and report delivery methods. Medical-related issues should still be diagnosed and treated by qualified medical institutions within China.

Genetic data is highly sensitive personal information. The service process should adhere to the principles of informed consent, purpose limitation, data minimization, and authorized access. Samples and personally identifiable information should be linked using codes. Data should be protected with access control and other security measures during transmission and storage, and must not be used for analysis or disclosure beyond the agreed scope without authorization. Before scheduling, please carefully read the privacy policy and informed consent form to confirm data retention periods, third-party processing, and methods for deletion or withdrawal of authorization. If you have any questions, please raise them before submitting your sample.

You can submit an inquiry through the "Contact Us" page on the website or via the currently available contact channels on the site. Staff will first understand your testing purpose and basic situation, then explain the available options, costs, sample requirements, estimated timelines, and privacy terms. After confirming the service content and completing the informed consent process, sampling will be arranged. To protect privacy, please do not fill in complete ID numbers, medical records, or non-de-identified genetic reports in public messages.

The PN (Personalized Nutrients) Factory provides personalized composite nutrient customization services, allowing the combination of different nutritional components and dosages based on professional protocols. Compared to fixed-formula off-the-shelf products, customized solutions emphasize adjusting combinations around individual test results and management goals, reducing redundancy, omissions, and usage complexity from taking multiple single products simultaneously. Customized nutrients are still nutritional support products, not equivalent to pharmaceuticals, and cannot replace disease treatment. Raw materials, production standards, suitability, and contraindications should be verified by professionals before ordering.

The required amount, tolerance, and priority of the same nutrient can vary between individuals. Age, diet, medication, lifestyle, laboratory indicators, and genetic differences can all influence protocol selection. Conventional off-the-shelf products are suitable for people with relatively clear needs and matching formulas; personalized customization is more suitable for situations requiring reduced formula overlap, adjusted dosage combinations, or improved convenience of implementation. The need for customization should be based on professional assessment, not solely on a single SNP result, and it is not recommended to self-combine multiple supplements.

Bob Miller has long been engaged in research on naturopathy, nutrigenetics, and functional genomics. He is the founder of the NGRI Nutrigenetics Research Institute and a key architect of the FGA analysis system. Project materials indicate he possesses over 30 years of relevant practical and case study experience, and continuously integrates data on genetic loci, metabolic pathways, and nutritional interventions into the FGA platform. His research and training outcomes are used to support professional interpretation; however, personal health decisions should still be made in conjunction with advice from qualified medical professionals.

The knowledge base of FGA is derived from peer-reviewed papers in fields such as nutrigenomics, single nucleotide polymorphisms (SNPs), metabolic pathways, and functional medicine, as well as case studies and algorithm correlation data systematically compiled by NGRI over the long term. The supporting literature materials on the site are aggregated into a paper library of approximately 651 pages. The platform also continuously updates its analytical framework by incorporating over 30 years of relevant practical case studies. Population associations found in papers do not automatically equate to diagnostic conclusions for any specific individual. Therefore, reports emphasize evidence levels, pathway relationships, and professional comprehensive judgment, and recommend verifying significant risk indicators through medical examinations.

The cost varies depending on the testing package, sample processing, report depth, whether one-on-one interpretation is included, and subsequent personalized nutrition services. Therefore, it needs to be confirmed according to the actual plan at the time of booking. Staff will list the included items, estimated timeline, potential additional fees, and refund or resampling rules before sampling and payment. When comparing, it is recommended to also consider factors such as locus coverage, laboratory quality, report content, and interpretation services, rather than focusing solely on a single quoted price.
