🩺 Quarterly Audit · 10 min read · Part 1 of 6

The Quarterly Self-Audit Protocol

Four times a year, thirty minutes, nine numbers. The audit is the site's feedback loop — the difference between guessing you're on track and knowing it. Print the sheet, run the checks, write the trend.

🔎 Evidence Snapshot ★★★★☆ Good — each marker's link to outcomes is well-established; the quarterly cadence is practical judgment, not trial-derived

What the evidence supports

Each marker on the sheet independently predicts mortality or functional decline in large cohorts.
ApoB predicts cardiovascular risk better than LDL-cholesterol alone.
Grip strength and the one-leg stand are validated, cheap proxies for whole-body aging.

What remains uncertain

Whether quarterly tracking itself changes outcomes is untested — the value is earlier detection and trend awareness, which is inference, not trial evidence.
Home devices vary; treat absolute values from consumer gadgets with a grain of salt and watch the trend instead.

Evidence last reviewed: August 13, 2026. Conclusions may change as new research is published.

numbers beat feelings

The Nine Numbers

Marker	Target	How often	How
💓 Blood pressure	<120/80 (home average)	Quarterly	Home cuff, 7-day protocol from the BP page
🧪 ApoB	<90 mg/dL (lower if high risk)	Annually	Blood test
🩸 HbA1c	<5.7%	Annually	Blood test
🍬 Fasting glucose	<100 mg/dL	Annually	Blood test, same draw
📏 Waist-to-height	<0.5	Quarterly	Tape measure at the navel, ÷ height
✋ Grip strength	Trending up or stable	Quarterly	Hand dynamometer, best of 3
🦩 One-leg stand	≥10 seconds each leg	Quarterly	Eyes open, hands at sides
😴 Sleep regularity	±30 min, 7 nights	Quarterly	One week of wake/sleep times
🔁 Resting heart rate	Trending down or stable	Quarterly	Morning, before standing, 3 days averaged

The Quarterly Rhythm

What each quarter's pass adds — annual labs ride on the Q1 audit

Running the Audit

📅 Anchor it to the calendar — solstices and equinoxes are the built-in reminders (the Habit Formation Protocol's cue rule).
📊 Record the trend, not just the number — four data points a year, four columns, one sheet. The trend is the diagnostic.
🧭 Out of range ≠ panic — one bad reading starts a conversation with your clinician, not a self-treatment program.
🖨️ Print this page — the print stylesheet strips the navigation; what's left is the sheet.

🔗 Each number has a home

Every row on the sheet links to its owning topic: the Biomarker Testing page for the labs, the Lipid Panel page for ApoB's case, the Hidden Vital Signs page for grip and balance, and the BP protocol for the measurement ritual. The audit is the summary; those pages are the detail.

The Series Map

Six parts, in audit order — each part assumes the one before it. The audit is the site's rhythm section: every other protocol produces results, and this one reads them four times a year. The audit is the site's rhythm section: every other protocol produces results, and this one reads them four times a year.

Part	Page	What you'll get
1	This page	The whole audit in one pass — the nine numbers, the rhythm, the printable core
2	Blood Markers Decoded	ApoB, HbA1c, glucose, lipids — the target ranges and how to read the report
3	Body Metrics	Waist, grip, one-leg stand — the targets and the measuring method
4	The Sleep & Recovery Audit	Regularity, resting heart rate, and the honest wearable question
5	Tracking Sheets & Trend Reading	The four-column log, spotting real change, keeping four quarters of history
6	Audit Shortcuts	Making it painless — calendar anchoring, the 30-minute kit, the batch labs

Where the Evidence Lives

🔬 What each lab means — the Biomarker Testing topic owns the full lab science and the reference ranges.
🫀 The cardiovascular core — the Blood Pressure and Lipid Panel topics own the numbers that matter most.
✋ The functional tests — the Hidden Vital Signs topic owns grip, balance, and what they predict.
😴 The recovery side — the Sleep Protocol owns the regularity science this audit samples.
📅 The habit that runs it — the Habit Formation Protocol owns the review rhythm (its Part 6 is this audit's twin).

Troubleshooting the First Quarter

🚩 The labs came back and I can't read them — Part 2 walks each marker with its target range; the Biomarker Testing pillar topic is the deep reference.
🚩 A number moved the wrong way — one quarter is weather, not climate. Re-check the method (fasting state, time of day, sleep the night before) and watch the trend across two quarters before acting.
🚩 The audit keeps slipping off the calendar — Part 6's shortcuts exist for this: anchor it to a fixed date, batch the labs, cap the whole thing at 30 minutes.
🚩 The same marker is out of range two quarters running — that is a real trend, not noise. Book the clinician conversation with the log in hand; the audit's job is to make that appointment happen early.
🚩 Numbers are fine but I feel the same — that's the audit working. It exists to catch drift before symptoms do; a boring report is the best report.

The Nine Numbers at a Glance

Measure	Target	How	Page
🫀 Blood pressure	<120/80 mmHg	Home cuff, 7-day average	Part 2
🧪 ApoB	As low as your risk profile warrants — discuss the target with your clinician	Fasting not required	Part 2
🩸 HbA1c	<5.7%	Any time of day	Part 2
🍬 Fasting glucose	<100 mg/dL (5.6 mmol/L)	8–12h fasted	Part 2
📏 Waist	<0.5 × height	Tape at the navel, relaxed	Part 3
✋ Grip strength	Above your age-decade median, trending up	Dynamometer, best of 3	Part 3
⚖️ One-leg stand	30+ seconds	Eyes open, hands free	Part 3
😴 Sleep regularity	Wake time within ±30 min, 6+ days/week	Log or wearable	Part 4
❤️ Resting heart rate	Trending down or stable at a healthy range	Morning, before rising	Part 4

Targets are for orientation, not judgment: age, sex, medication, and personal risk shift every one of these. The audit compares you to your own last quarter — the ranges only flag when a clinician conversation is due, which is precisely the early warning this whole system exists to give.

If You Only Do Three Things

🫀 The cardiovascular five — blood pressure, ApoB, HbA1c, waist, and grip. Everything else in this series is refinement of these five.
📋 One sheet, four columns — measure, this quarter, last quarter, last year. Part 5 owns the format; the comparison is the entire point.
⏰ One fixed date — the audit that isn't calendared doesn't happen. First Sunday of the quarter, thirty minutes, done.

Questions, Answered Briefly

❓ Why quarterly and not monthly? — Most biomarkers move on a months-long timescale; monthly testing mostly measures noise. Quarterly catches real trends without creating number-anxiety.
❓ Which numbers matter if I only track five? — Blood pressure, ApoB, HbA1c, waist, and grip. They cover the cardiovascular, metabolic, and functional cores in five measures.
❓ Do I need to fast before labs? — For glucose and a standard lipid panel, yes (8–12 hours); for ApoB and HbA1c, not strictly. Part 2 owns the details.
❓ What if I miss a quarter? — Record what you can when you remember, keep the sheet alive, and resume at the next anchored date. A gap is a gap, not a verdict — the trend survives one missing row.
❓ Is this a substitute for a doctor? — No. The audit tracks and trends — it catches drift early; anything outside the target ranges goes to a clinician, with the log in hand.

This Page in One Workflow

1. Anchor — a fixed audit date each quarter (first Sunday, per Part 6).
2. Collect — labs ordered the week before; home measures the morning of (Parts 2–4).
3. Record — everything into the four-column sheet (Part 5).
4. Compare — against last quarter and last year, not against arbitrary ideals.
5. Decide — one action item per marker that moved, and nothing more. The audit ends in a to-do, not a guilt trip — and the to-do is one item, written down, with a date.

The Audit Setup Checklist

Audit date anchored — same Sunday each quarter, in the calendar now
A two-hour block protected on audit morning — labs, measures, sheet, done
Lab order requested one week ahead (ApoB, HbA1c, fasting glucose, lipids)
Morning-of protocol known: fasted labs, then the home measures, then breakfast
Last year's row visible for the long-trend comparison
Blood pressure cuff and scale ready for the morning-of measures
Grip and balance tests staged (Part 3)
Sleep log or wearable synced — one week of regularity data before the audit morning
Resting heart rate baseline from the morning check
Four-column sheet printed or templated (Part 5)
Last quarter's numbers on hand for the comparison
One action item committed per moved marker — written, dated, and single
Anything out of range scheduled for a clinician conversation
Waist tape and dynamometer bought or borrowed — the morning-of kit is complete
The audit ends with one committed action item, written down

The Bottom Line

Nine numbers, quarterly, 30 minutes — that's the entire protocol.
Labs annually, body quarterly — the rhythm that keeps costs low and signal high.
Track the trend — one year of data beats any single reading.
Out-of-range starts a clinician conversation — the audit detects, medicine decides.
