The blood panels Peptide AI reads, marker by marker
Upload a lab PDF or type the values in. The app sorts them into two panels, scores each one, flags anything that needs a doctor soon, and draws every marker against your dose timeline.
A lab report lists results in whatever order the laboratory chose. Peptide AI regroups them by what they tell you about: how your body is handling fuel, and how much low-grade inflammation is running in the background. This page lists every marker in those two panels, says in one line what each measures, and explains what the score, the grade and the flags mean. Each marker links to its own page.
Getting results in
Two ways. Upload the PDF your lab or patient portal gives you and the parser reads the supported markers from it, or enter values by hand from a paper report. Each value is stored with the date of the draw and the units printed on the report, because the same quantity has a different number in mg/dL and mmol/L. A second report adds a second point to every line. The bloodwork tracking page covers the upload flow.
The metabolic panel
Fourteen markers covering glucose control, blood fats, liver, kidney, uric acid and vitamin D. It is not the same thing as the laboratory "basic" or "comprehensive" metabolic panel, which the metabolic panel guide untangles.
| Marker | What it measures |
|---|---|
| Fasting glucose | Blood sugar after at least 8 hours without food. |
| Fasting insulin | How much insulin it takes to hold that fasting glucose; rises early in insulin resistance. |
| HbA1c | Share of haemoglobin carrying glucose; reflects roughly the previous two to three months. |
| LDL cholesterol | Cholesterol carried in low-density lipoproteins; usually calculated, not measured. |
| HDL cholesterol | Cholesterol carried in high-density lipoproteins. |
| Total cholesterol | All the cholesterol in the sample, across every lipoprotein. |
| Triglycerides | Circulating fat; the lipid that moves most with recent meals, alcohol and weight change. |
| ALT | Enzyme concentrated in liver cells; leaks into blood when they are injured. |
| AST | Enzyme in liver and muscle; rises after liver injury and after hard exercise. |
| eGFR | Estimated kidney filtration rate, calculated from creatinine, age and sex. |
| Creatinine | Waste product of muscle, cleared by the kidneys. |
| BUN | Blood urea nitrogen, a protein breakdown product cleared by the kidneys; moves with hydration and protein intake. |
| Uric acid | End product of purine breakdown; high levels are linked with gout and kidney stones. |
| Vitamin D (25-OH) | The circulating storage form of vitamin D. |
The inflammatory panel
Eight markers. Some are classic acute-phase proteins that the liver makes more of during inflammation; some are signalling molecules upstream of that response; one falls rather than rises. The inflammatory markers guide explains how they relate.
| Marker | What it measures |
|---|---|
| hs-CRP | C-reactive protein measured down to low levels; the most studied marker of low-grade inflammation. |
| IL-6 | Interleukin-6, a signalling protein that drives the liver to make CRP. |
| Ferritin | Iron storage protein; also rises with inflammation, so a high value is ambiguous. |
| Homocysteine | Amino acid intermediate; rises with low B12, folate or kidney function. |
| ESR | How fast red cells settle in a tube; a slow, non-specific inflammation signal. |
| Fibrinogen | Clotting protein that also rises as part of the acute-phase response. |
| TNF-alpha | Tumour necrosis factor alpha, an inflammatory signalling protein mostly measured in research. |
| Albumin | Main blood protein; falls during inflammation and with poor nutrition or liver disease. |
Other markers it reads
IGF-1, insulin-like growth factor 1, is read and charted on its own, because it is the marker studies of several peptide classes measure. The thyroid markers TSH, free T3 and free T4 are read and plotted too. Of the 36 biomarkers the parser recognises, these are the ones described on this site.
Panel scores and the overall grade
Each panel gets a score from 0 to 100, and the two combine into an overall grade. The score summarises where your markers sit relative to their ranges, so one number moves when the panel improves or worsens as a whole. Treat it as a summary of the report, not a diagnosis and not a risk prediction. A panel score can be high with one marker that matters a great deal, and lower with several small deviations that do not. That is why the marker list stays on screen under the score, and why the score never replaces reading the markers.
Flags
Separately from the score, the app flags values that warrant prompt consultation with a physician. A flag means the number is far enough from the expected range that waiting for the next routine appointment is not the sensible plan. It does not say what is wrong. Ordinary out-of-range results, the H and L your lab prints, are shown as the lab reported them; the lab report guide explains why a single H is common in healthy people.
The timeline
Every marker is plotted over time, with the weeks you were on each compound from the dose log and protocol planner drawn underneath. Two draws become a line with context. The timeline does not prove cause. It shows what else changed, which is where an honest reading starts. Before reading a change between two points, check whether it is bigger than normal day-to-day variation; the biological variation page shows how to tell.
What it is not
The app reads, groups, scores and plots. It does not order tests, it does not diagnose, and a score or a flag is a reason to talk to the clinician who ordered the test, not a substitute for that conversation. Lab results can be exported or deleted with the rest of your data; see privacy and your data.
Where to start
Upload the most recent lab PDF you have as a baseline, then keep logging doses, food in nutrition tracking and sessions in the training log. The next report will land on a timeline that already has the context around it. The app is on the download page.
Questions people ask
Which blood markers does Peptide AI read?
A metabolic panel of 14 (fasting glucose, fasting insulin, HbA1c, LDL, HDL, total cholesterol, triglycerides, ALT, AST, eGFR, creatinine, BUN, uric acid, vitamin D), an inflammatory panel of 8 (hs-CRP, IL-6, ferritin, homocysteine, ESR, fibrinogen, TNF-alpha, albumin), plus IGF-1 and TSH, free T3 and free T4.
How does the panel score work?
Each panel gets a score from 0 to 100 summarising where its markers sit relative to their ranges, and the two panels combine into an overall grade. It is a summary of the report, not a diagnosis or a risk prediction.
What does a flag in the app mean?
It marks a value far enough from the expected range that it warrants prompt consultation with a physician rather than waiting for a routine visit. It does not say what the cause is.
Can I enter results without a PDF?
Yes. Values can be typed in by hand with the draw date and units. They are plotted the same way as uploaded results.
