Most blood analytes do not change enough in a month to beat their own noise. Here is the short panel worth drawing monthly, what belongs on a slower cadence, and how to standardize the draw so the numbers mean something.
A technical guide to building a baseline blood panel you can track over years: which analytes to order, how to control preanalytical variation, and the math that tells you whether a change is real.
How to choose a blood test cadence from analyte kinetics and biological variation, how to tell a real change from assay noise using reference change values, and how to structure the data so you can analyze it yourself.
A working list of blood, molecular, and continuous biomarkers worth tracking on yourself, with the biological-variation math that tells you when a change is real and when it is noise.
A working guide to pulling your lab results out of a patient portal as structured data, normalizing them, and analyzing them with the right statistics: reference intervals, analytical and biological variation, and reference change values.
Monthly blood work is physiologically safe for almost everyone, but most analytes change slower than the noise floor of the assay. Here is how to pick a testing interval per marker, standardize the draw, and detect real change in your own data.
