Understand your labs.
A free online tool that reads your blood panel against the current research on women's iron.
Works with anything from a CBC to a full iron panel.
Evidence
700+ studies appraised
Every threshold in the tool traces to a specific peer-reviewed paper.
Scope
Not a diagnosis
Femme Fortified is a research-education tool. We translate. Your clinician diagnoses.
Privacy
Nothing stored on our server
Your lab values don't persist anywhere. We don't store anything server-side.
What you'll get
What the research says about values like yours
We take what you enter (ferritin, hemoglobin, MCV, anything you have) and look at it holistically. All the information together tells a different story than any single number.
The research behind every threshold
Every number we compare you to comes from a specific study or consensus body. Each is badged by quality of evidence: High quality, Preliminary, or Consensus.
A PDF to bring to your doctor
A personalized write-up and a question prompt list you can print.
How it works
01
Tell us about you
Age, life stage (cycling, pregnant, postpartum, perimenopausal, postmenopausal), and dietary context.
02
Enter the labs you have
Whatever's on your last panel. The tool adapts to what you enter. With limited inputs, it names the specific test that would confirm or refine the result.
03
Read your result
A plain-language read on your specific pattern, the research behind it, and the questions worth asking your doctor.
Who this is for
You have an iron panel
Want to understand what the research says about your values.
You've been told your labs look “normal”
But you feel otherwise, and you want to see whether the research reads your numbers the same way.
You have an appointment coming up
And you want to walk in informed, with specific research-backed questions ready.
You want rigor
You want to read your own labs with the same rigor the research affords.
Not for pediatric users (under 17). Not a replacement for a clinical visit. Does not diagnose.
What Femme Fortified is
A weekly newsletter on women's iron, energy, and hormones. We read the peer-reviewed research — studies written for other scientists, often buried in jargon — translate each one into plain language, and pull out the specific actions you can take from it.
Frequently asked
What is this tool, exactly?
A free online read of your iron blood labs. You enter whatever values you have and a bit about your life stage. We classify the overall pattern based on the published research on women's iron health. Not a diagnosis. Not a replacement for a clinical visit. It translates the research so you can walk into your next appointment prepared.
Is this a diagnosis?
No. We don't diagnose, treat, or prescribe. We translate the research on women's iron labs into plain language. Your clinician is the only person qualified to diagnose or make clinical decisions about your health.
What happens to my lab values?
The tool runs entirely in your browser. No server sees or stores your lab values while you use it. You don't need to provide an email to use the tool. If you choose to download a PDF, your values pass through our PDF generator for the few seconds it takes to render, then they're discarded, and your email joins the Femme Fortified newsletter. Nothing else is retained.
What labs do I need to use the tool?
At minimum, one lab value plus some basic context (age, life stage). The more you have, the more specific your result. The tool accepts: hemoglobin, MCV, MCH, RDW (from a standard CBC); ferritin, transferrin saturation, serum iron, TIBC (from an iron panel); sTfR, CRP, reticulocyte hemoglobin (less commonly ordered). If you only have a CBC, the tool will tell you what pattern your red blood cells fit and which specific test to add if you want to confirm or refine the result.
What does "High quality" / "Preliminary" / "Consensus" mean on my result?
Those are evidence-strength badges. High quality means multiple clinical trials or large analyses that agree. Preliminary means early evidence, usually from one study, that hasn't been replicated. Consensus means major health organizations agree (WHO, ACOG, EASL, and similar). The goal is to be transparent about how strongly the research supports each claim.
Can I use this if I'm pregnant or postpartum?
Yes. The tool applies pregnancy trimester-specific research thresholds if you tell us you're pregnant and enter your due date. Postpartum within six months of giving birth applies distinct thresholds. Lactation is captured under the postpartum track.
