Precision Medicine Quiz
Precision medicine offers five very different types of tests. Answer eight questions and we'll rank the ones that fit your biology, goals, and budget.
Precision medicine replaces the one-size-fits-all model of healthcare with interventions tailored to an individual's genetic makeup, microbiome, metabolic phenotype, and environmental exposures. The testing landscape has expanded dramatically since the Human Genome Project and now includes four main categories of consumer-accessible tests. Polygenic risk scores use genome-wide association study data to calculate your relative risk for complex diseases like type 2 diabetes, coronary artery disease, and several cancers based on the cumulative effect of hundreds or thousands of common genetic variants. Unlike single-gene tests, polygenic scores capture the distributed genetic architecture of most common diseases.
Whole genome sequencing provides the most comprehensive genetic data available — all 3.2 billion base pairs — but interpreting the output requires sophisticated bioinformatics and clinical genetics expertise. Clinical-grade sequencing from providers like Veritas Genetics or Dante Labs identifies pathogenic variants in known disease genes including BRCA1/2 (hereditary breast and ovarian cancer), Lynch syndrome genes (hereditary colorectal cancer), and cardiomyopathy genes, which can be directly actionable for screening and prevention. Consumer sequencing from companies like 23andMe provides a lower-resolution subset of this information and is better understood as a research-grade snapshot than a clinical diagnostic.
Pharmacogenomics testing analyses variants in the cytochrome P450 enzyme genes (CYP2D6, CYP2C19, CYP3A4, and others) that control the metabolism of a majority of commonly prescribed drugs. These variants determine whether a patient is a poor, intermediate, normal, or ultra-rapid metaboliser of specific medications, which directly affects therapeutic efficacy and adverse drug reaction risk. For example, approximately 25% of people carry variants in CYP2C19 that make standard doses of the antiplatelet drug clopidogrel (Plavix) ineffective after cardiac stenting — a fact that pharmacogenomics testing can identify before a potentially preventable cardiac event. GeneSight, Genomind, and hospital-based pharmacogenomics programs now routinely offer this testing.
Continuous glucose monitoring (CGM) for non-diabetics provides real-time metabolic data that no static blood test can match. Research from the Zeevi and Sonnenburg labs at the Weizmann Institute and Stanford respectively showed that glycaemic responses to identical foods vary dramatically between individuals based on gut microbiome composition, genetics, and baseline metabolic health — making personalised dietary guidance based on CGM data substantially more effective than general population dietary guidelines. This quiz identifies whether your health goals and current situation point toward any of these testing approaches as a practical starting point.
The value of any precision medicine test depends entirely on what you do with the information. Polygenic risk scores and genetic variants become clinically useful when reviewed with a healthcare professional who can contextualise them alongside family history, clinical biomarkers, and lifestyle factors. Pharmacogenomics results are most valuable when shared with your prescribing physicians — ideally before you start any new medication rather than after experiencing an adverse reaction. CGM data is most actionable when combined with structured dietary experimentation: tracking your glucose response to specific foods over 2–4 weeks provides a personalised dietary map that no generic nutrition guide can offer. This quiz helps you identify which type of precision medicine testing is the most logical starting point given your specific health concerns and goals.
