The Biomarker Guide: read your blood work like a clinician
Most people get a blood test once a year, glance at the flags, and file it away. That panel contains a decade of early warnings — if you know how to read it.
These articles cover the markers standard panels hide (ApoB), the ones that catch insulin resistance ten years before diabetes (HOMA-IR, TyG), and — most importantly — which foods and training choices move which numbers.

Part 1
The cholesterol number your standard panel hides — ApoB explained
Your LDL cholesterol can look fine while your real cardiovascular risk is high. The number that resolves the contradiction is ApoB — and most standard panels do not show it.
Part 2
ApoB high, LDL normal: what now?
You measured ApoB, it came back high, but your LDL cholesterol looked fine — so what do you actually do about it? Here is the action plan that follows a high particle count.
Part 3
"Am I becoming insulin resistant?" HOMA-IR and TyG, explained
Insulin resistance builds for years before fasting glucose ever looks abnormal. Two simple indices — HOMA-IR and TyG — catch it early, and Misi computes both from your bloods.
Part 4
HbA1c is 5.7–6.0? The exact dietary changes that move it (and how fast)
An HbA1c in the 5.7–6.0% band is prediabetes — a warning, not a sentence. Here are the dietary changes with the strongest evidence for lowering it, how quickly they show up, and how Misi tracks the shift.
Part 5
High triglycerides: the 6 swaps with the strongest evidence
Triglycerides respond to diet faster and harder than almost any other lipid marker. Here are the six changes with the best evidence behind them — and how quickly they work.
Part 6
hs-CRP above 1.0: the anti-inflammatory plate, quantified
A high-sensitivity CRP above 1.0 mg/L signals low-grade inflammation that quietly raises cardiovascular risk. Here is what actually lowers it — the dietary pattern, quantified, and the habits that matter most.
Part 7
Ferritin low but iron "normal"? Why you’re flat in the gym
Your iron came back "normal," yet you’re exhausted and your training has stalled. The marker your doctor may not have flagged is ferritin — and it can be depleted long before anaemia shows up.
Part 8
"Is my heart heading for trouble?" Reading your 10-year ASCVD risk
Heart disease rarely announces itself until it is advanced. Your 10-year ASCVD risk score turns routine bloods into an early-warning number — and Misi calculates and tracks it for you.
Part 9
Glucose spikes and the CGM hype — what your fasting markers really tell you
Continuous glucose monitors have gone mainstream for people without diabetes. Here is what the spikes do and do not mean — and the validated markers that tell you more.
Part 10
Diet-to-blood-marker bridges: which foods move which numbers
A blood test tells you where you are, not what to change. Misi builds a bridge from each dietary lever to the marker it drives — then tracks whether your numbers are actually moving the right way.
Part 11
Meals that fit your bloodwork, not just your macros
Two meals can hit identical macros and have opposite effects on your lipids, inflammation and glucose. Misi scores meals against your actual blood results.
Part 12
"What if my bloods flag something serious?" Critical biomarker alerts
A genuinely alarming lab value should never get lost in a PDF. Misi scans your uploaded bloods and surfaces critical readings so you can act — and talk to a doctor — fast.
Part 13
New bloods in, whole new plan out
Most apps let you log a blood test and then do nothing with it. In Misi, new biomarker results can regenerate your entire plan — training, nutrition and supplements — around what your body just told you.
Part 14
"Which of my habits is actually working?" Mapping habits to bloods
You changed five things at once and your numbers improved — but which change did the work? Misi correlates the habits you log with the biomarkers that move.
Part 15
Millions may be getting the wrong cholesterol test
Standard LDL cholesterol has been the default heart-risk number for decades. A 2026 analysis adds to the case that ApoB is the more accurate measure for treatment decisions — and that relying on LDL alone is misclassifying real risk.
Part 16
How inflammation speeds up your biological clock, according to a national health survey
Using data from the CDC’s NHANES survey, researchers linked chronic inflammation directly to a faster "pace of aging" on the DunedinPoAm epigenetic clock — and showed that faster clock speed predicted mortality.
Part 17
A blood test that may flag depression risk before symptoms appear
Depression is usually diagnosed after symptoms are already disrupting someone’s life. A 2026 study on immune-cell aging in the blood suggests a biological signal may be detectable earlier than that.
Part 18
Cardiovascular-kidney-metabolic syndrome: the one panel that connects three risks
Heart, kidney and metabolic disease have traditionally been managed by three different specialists looking at three different charts. A newer diagnostic framework, CKM syndrome, treats them as one interconnected condition — and it changes which blood markers matter most.
Part 19
The vitamin deficiency that can be mistaken for normal aging
Adults need only about two micrograms of vitamin B12 a day — an almost unmeasurably small amount — yet a shortage can cause fatigue, brain fog and muscle weakness that’s routinely written off as "just getting older."
Part 20
A common "focus" amino acid was linked to nearly a year of lost lifespan in men
Tyrosine is a staple of brain-health and pre-workout supplements. A study of over 270,000 UK Biobank participants found higher blood tyrosine levels were consistently associated with shorter lifespan in men — but not women.
Part 21
Even a sunny summer may not fix your vitamin D if you’re in a high-risk group
A study of nearly 300 people across northern Britain found vitamin D levels stayed low year-round in older adults and people from minoritized ethnic backgrounds — summer sunshine included. The "just get outside" advice may not be enough.
Part 22
A large study links higher vitamin C levels to healthier brain structure in older age
In a study of more than 2,000 older adults in Japan, people with lower blood vitamin C had less gray matter and weaker connectivity in a brain network tied to memory and attention. It doesn’t prove cause and effect, but it’s a real signal worth tracking.
Part 23
Can lifestyle changes alone move the needle on testosterone? A decade-long randomised trial has data
A long-term follow-up of the T4DM trial — which randomised over 1,000 men with prediabetes or newly diagnosed diabetes to testosterone treatment plus a lifestyle program, or lifestyle alone — offers rare, multi-year data on what actually happens to metabolic health in men pursuing "hormone optimization."
Part 24
Multi-cancer early detection blood tests: exciting idea, still-developing evidence
A single blood draw that screens for dozens of cancers at once sounds like the future of preventive medicine. The NHS-Galleri trial and related research show real promise — and also exactly why these tests are not yet ready to replace standard screening.
Part 25
Muscle pain on statins: how much is the drug, and how much is expectation?
Muscle aches are the most commonly reported reason people stop taking statins. Blinded trial evidence tells a more precise story than "the drug causes muscle pain" — and getting it right matters for anyone weighing cardiovascular risk against a symptom.
Part 26
Microplastics were found inside arterial plaque — and linked to more heart attacks and strokes
A landmark study found microplastics embedded in the artery walls of over half its patients, and those with plastic in their plaque had a substantially higher rate of heart attack, stroke or death over the following years.

Frequently asked
Which blood markers should I actually track?
A high-yield core: ApoB (cardiovascular risk), HbA1c and fasting insulin (metabolic health), hs-CRP (inflammation), ferritin (iron status), vitamin D, and a standard CMP + CBC for kidney, liver and blood-count trends. Misi tracks 50+ markers parsed automatically from your lab PDF.
Can diet really change my blood results?
Yes — with specificity. Soluble fibre and omega-3 intake move ApoB and triglycerides; carbohydrate quality and timing move HbA1c and fasting glucose; weight loss and polyphenol-rich foods move hs-CRP. The bridge between a specific food pattern and a specific marker is exactly what Misi automates.
How often should I re-test?
Quarterly for markers you are actively trying to move; annually for a full panel if everything is in range. Misi generates a retest cadence per marker based on your baseline and risk.
