Dried Blood Spot Testing
At-home blood testing for fatty acids, vitamins, and hormones
$100–$200
7–10 business days
Dried blood spot (DBS) testing uses a simple finger prick to collect blood onto filter paper, which is then mailed to a lab for analysis. DBS enables at-home testing for omega-3 fatty acids, fat-soluble vitamins, thyroid hormones, and more — no phlebotomy required.
DBS testing has become increasingly validated for clinical use, offering convenience and accessibility for patients who can't easily get to a lab or prefer home collection. The technology is particularly useful for tracking omega-3 levels, vitamin D, and other markers over time.
What It Measures
Omega-3 index (EPA + DHA percentage in red blood cells)
Omega-6 to omega-3 ratio
Vitamin D (25-OH vitamin D)
Vitamin A, E, and K (fat-soluble vitamins)
Thyroid hormones (TSH, free T4, free T3) on some panels
HbA1c (3-month blood sugar average)
Why Gabriel Recommends It
Omega-3 index is one of the most important modifiable risk factors for cardiovascular disease, brain health, and longevity — yet most people never measure it. A target omega-3 index above 8% is associated with significant reductions in sudden cardiac death and all-cause mortality. DBS testing makes it easy to measure your omega-3 index at home and retest every 3–6 months to optimize your levels. Gabriel uses DBS omega-3 and vitamin D data to guide supplementation and track progress over time.
What to Expect
A simple at-home finger prick using a lancet. You'll collect a few drops of blood onto special filter paper, let it dry, and mail it in the prepaid envelope. Results arrive in 7–10 business days. Upload to Gabriel for omega-3 and micronutrient optimization protocols.
How Gabriel Interprets This
Conventional practitioners read these results through a disease-focused lens — looking for what's broken. Gabriel reads them through a naturopathic lens — looking for what's out of balance and how to restore it. We see optimal ranges, not just "normal" ranges. We connect findings across all your diagnostics to reveal patterns that siloed specialists miss.
