At The Wellness a phlebotomist draws your blood from a vein in clinic, the panel includes the markers the cardiovascular guidelines name, and a doctor reads every result with you.
Results that nobody acts on are a known failure in outpatient care. A systematic review of 19 studies found that between 6.8% and 62% of laboratory results were not followed up, and missed results were linked to delayed diagnoses.

The 2019 European dyslipidaemia guideline recommends ApoB for cardiovascular risk assessment, particularly in people with high triglycerides, diabetes, obesity or metabolic syndrome. Mach and colleagues, 2019 ESC/EAS Guidelines for the management of dyslipidaemias, European Heart Journal, 2020
In a 2025 comparison of 34 routine chemistry tests, finger prick and venous samples agreed for almost all of them, and glucose was the one that missed the stricter CLIA 2024 limits, so the sampling method matters for some markers more than others.
