Six ways into genomics. Each guide gives you useful language, practical questions, and a next step for learning more.
Meet the building blocks: DNA, genes, chromosomes, and the variation that connects them.
Explore the guideCompare targeted tests, exome sequencing, and whole genome sequencing by what they measure.
Explore the guideLook beyond the collection box to test scope, consent, costs, and support after results.
Explore the guideNavigate genes, reference assemblies, variant records, and the evidence behind an entry.
Explore the guideLearn how selected markers are measured and why genotyping differs from sequencing.
Explore the guideExplore ancestry, inherited variation, precision medicine, and the importance of context.
Explore the guideCollection kits, laboratory methods, and interpretation are different parts of the process. Understanding the difference helps you look beyond a product name and ask what a test can actually tell you.
Understand the testing processHow a sample is obtained, labeled, and sent to the laboratory.
Which positions or regions the laboratory examines—and what it might miss.
How the findings are evaluated against evidence and the question being asked.
Practical guides to the science, the decisions, and the questions that deserve more than a quick answer.
DNA testing creates choices about samples, digital records, research, and relatives. Learn which privacy questions deserve clear answers before you test, enable matching, or upload a DNA file, and understand the practical limits of withdrawal and deletion.
Precision medicine can use genomic information to make care more specific. Understand where genetics helps, how evidence is evaluated, why uncertainty and population differences matter, and which questions connect a test result with a meaningful clinical discussion.
A DNA kit is the starting point of a service, not a description of everything it can tell you. Compare the question being asked, the laboratory method, the interpretation, and the choices you retain over your sample and data.
Here are a few of the most useful ones to ask as you begin.
Genetics often focuses on individual genes and inheritance. Genomics looks more broadly at the genome and relationships among genetic information, biology, and environment. Start with our genomic DNA guide for the key terms.
The kit collects a sample. What gets measured depends on the laboratory test paired with it. Some services examine selected markers; others sequence specified regions. Learn what to compare in a DNA test kit.
They describe related but different concepts. Selected-marker genotyping examines chosen positions, while sequencing determines base order across the regions covered by the test. Sequencing can also be used to call genotypes. Read the method comparison.
A genetic finding has to be interpreted in context. Test scope, family and medical history, environment, and evidence can all matter. A risk association is not a guaranteed outcome. Our results guide explains common report language.
Start with a question: are you looking for a gene, a genomic location, or a variant classification? Then check the reference and record details. The genome database guide introduces official resources.
Geneomix is an educational resource. Explore the guides here, and contact a testing provider or qualified healthcare professional for questions about a sample, testing, or an individual report.
