The 10 markers you'd never see on the Basic panel.
The Basic profile gives you 30 markers — a strong foundation. But the Complete profile adds 10 more, covering immune function, mineral balance, cellular energy and deeper liver & kidney clearance. These are the markers that turn a snapshot into a strategy.
Covers blood sugar, insulin, liver, kidney, heart, thyroid and the essential nutrients. A solid baseline.
Everything in Basic, plus immune, mineral, growth and cellular energy markers. The full picture in one draw.
Your immune system's first line of defence
White blood cells, platelets and ESR (sedimentation rate) tell you whether your immune system is under stress before you feel it. The Basic panel skips them entirely — you'd be flying blind on inflammation and infection.
Deeper liver & kidney clearance
Bilirubin catches bile-flow and red-blood-cell breakdown that ALT and AST alone miss. Urea adds a second kidney-clearance lens on top of creatinine/eGFR. Both are the markers a clinician asks for when something looks borderline.
Mineral balance you can't guess
Copper, ceruloplasmin and zinc are a tightly coupled trio. Low zinc kills recovery; high copper dysregulates mood and sleep. You can't feel your way to these numbers — you have to measure them.
Growth & energy at the cellular level
IGFBP-3 is the binding partner to IGF-1 — together they tell the full growth-hormone story. Lactate reveals how efficiently your cells produce energy. Both are invisible on the Basic panel.

Insight, education & lifestyle advice in the app
You see what's steady, what's drifting, what it may mean, and concrete lifestyle steps to try first nutrition, sleep, movement, stress. From here, you choose the next step.
Everything people ask before their first test.
Insight, education, prevention, supplements and lifestyle guidance all in one app.
- The sample is processed at a certified partner lab, your biomarkers are compared against your own history in the Haylo app, and you get a personal analysis usually in under 72 hours. No lab portal, no PDFs, no chasing.
- No. Haylo delivers analysis, insight, education, prevention and lifestyle advice not a diagnosis. It's designed to help you understand your own biomarkers and act on them with targeted supplements and lifestyle changes.
- Which markers are steady, which are drifting versus your own baseline, what that pattern may mean in plain language, and specific lifestyle steps to try first targeted to the markers that moved, not generic wellness tips.
- Concrete, marker-linked suggestions across nutrition, sleep, movement and stress. For example: if ApoB is drifting up, you'll see food-first steps tied to that specifically with next month's test to see if it actually worked.
- No. 'Do nothing' is a valid choice most people, most months, don't need to act. Haylo just keeps monitoring. If anything meaningful changes next cycle, you'll know.
- Every suggestion is tied to a specific marker that moved in your own bloodwork nothing generic. You always decide whether to act, and we retest in 90 days to confirm it worked.
- A one-off check-up compares you against a generic population range. Haylo compares each quarterly result against your own history, so it catches a slow drift months before a single test would look 'abnormal'.
- Yes. Your data is stored securely in your own Haylo account, and it's never sold or shared without your permission.
