This isn't a score, and it isn't a diagnosis. It compares three of your existing lab results with what published fertility research shows in women actively trying to conceive, and tells you plainly whether a number sits where the evidence is reassuring or where it is worth a closer conversation with your provider. Enter what you have and skip what you don't.
The most useful marker here, and the one most often waved through. It only means something if it is taken about 7 days after you actually ovulated, which isn't always "day 21." A regular cycle can still show a progesterone below the range where conception cycles tend to cluster.
Your iron reserve. The number with the strongest fertility evidence behind it is not a high "optimal" target. It is the deficiency line of 30, which a 2025 clinic study linked to live-birth rates.
Standard labs often call anything up to about 4.0 "normal." When you are actively trying to conceive, many fertility clinicians use a more cautious line of 2.5, particularly when thyroid antibodies are also positive.
People will sell you "fertility-optimal" targets for a dozen markers. I kept this reader to the three where the published evidence is strong enough to say something honest to someone I have never met. Most "optimal range" numbers you see online are functional medicine convention, not established fertility thresholds, so they don't belong in a free tool that puts your name on the answer. Advanced Diagnostics covers the rest and marks clearly what is evidence and what is informed preference.
Advanced Diagnostics reads every category for your specific driver and gives you the cross-pattern map, the 90-day roadmap and the exact words to raise each number with your GP. Use it to read the labs you already have, or 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 with ranges reported in published fertility research. It can't see the rest of your labs, your history, your cycle timing or your medications, and all of these change how a single number should be read.
Reference ranges and units differ between labs and countries. A result marked here as "worth a conversation" means exactly that: a prompt to talk to 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 taken for a confirmed deficiency, under medical supervision.
