Begin with the output
An age in years, an outcome-associated composite and a pace measure are different model outputs. Before comparing prices, make sure the tests address the same question.
Source 1: Aging / Levine et al.Source 2: eLife / Belsky et al.Use the comparison tool deliberately
Choose up to three profiles and read the method, sample, evidence and main limitation together. A blank or unverified field is a gap in the review, not a positive or negative feature of the test.
Compare the complete commitment
A kit price can omit collection, delivery, tax, interpretation or future membership fees. Save the dated provider terms and ask which assay and model version would be used if you retest.
