Biological age tests run from about $75 for a blood-chemistry clock to $300-$500 for a methylation array, with outliers above $1,000. Here is what each tier measures, how reliable it is, and how to compute the same clocks yourself from raw data.
How to get a useful AI-generated report from your own DNA data, which file formats matter, and where the interpretation breaks down.
A technical guide to DNA methylation testing — arrays versus whole-genome bisulfite sequencing versus nanopore, what the raw files look like, how to process them, and how much of the signal is real.
A technical walkthrough of DNA methylation testing. Compares arrays, bisulfite sequencing and nanopore, then covers the IDAT pipeline and clocks.
A technical answer to which genetic sites are worth uploading raw DNA to, what the array file contains, and how to run the same analyses yourself with plink, bcftools, and an imputation server.
What biological age tests measure and which clocks are worth running. Covers computing them from IDATs and a blood panel, and how much is noise.
