This isn’t a score, and it isn’t a diagnosis. It reads three of your existing lab numbers against what the published fertility research shows in women who are actively trying to conceive — and tells you, plainly, whether a number sits where the evidence is reassuring or where it’s worth a closer conversation with your provider. Enter what you have. Skip what you don’t.
The single most useful marker here — and the one most often waved through. It only means something if it’s drawn about 7 days after you actually ovulated, not strictly “day 21.” A regular cycle can still show a progesterone below the range conception cycles cluster in.
Your iron reserve. The number with the strongest fertility evidence behind it isn’t a high “optimal” target — it’s the deficiency line below 30, which a recent trial linked directly to live-birth rates.
Standard labs often call anything up to ~4.0 “normal.” When you’re actively trying to conceive, many fertility clinicians use a more cautious line at 2.5 — strongest when thyroid antibodies are also positive.
There are a dozen markers people will sell you “fertility-optimal” targets for. We kept this reader to the three where the published evidence is genuinely strong enough to say something honest to a stranger. Most “optimal range” numbers you’ll see online are functional-medicine convention, not established fertility thresholds — so they’re not in a free tool with your name on the answer. The full decoder handles the rest, clearly flagged for what’s evidence and what’s informed preference.
Advanced Diagnostics reads every category for your specific driver — the cross-pattern map, the 90-day roadmap, and the exact scripts to bring each number to your GP. Read your existing labs against the framework, or use it to request the right panel next time.
Open Advanced Diagnostics →This reader is educational, not medical advice, and it isn’t a diagnosis. It compares three lab values against ranges reported in the published fertility literature — it can’t see the rest of your labs, your history, your cycle timing, or your medications, all of which change how any single number should be read.
Lab reference ranges and units vary between labs and countries. A result flagged here as “worth a conversation” is exactly that — a prompt to talk with your own doctor, who can interpret it in full context. Never start or change a supplement, medication, or dose based on this tool. Iron in particular should only be supplemented with confirmed deficiency under medical supervision.
