Baseline: Blood tests that remember your history
A membership blood-testing service that sends phlebotomists to homes in India and compares recurring biomarker results with each member’s own history.
Field notes
Baseline uses age to select an initial testing panel instead of asking members to compare a menu of packages. The visible sample begins with 41 core markers, expands to 52 after fifty, and shows results grouped across nine systems. Its example of adaptive testing adds reticulocytes, cystatin C, and a urine albumin ratio after low ferritin and borderline kidney-function results, while stable markers can move to annual checks.
