Iron-Deficiency Anaemia: Your Blood Tests and Treatment as Research Data

Every figure in this guide comes from a published source, linked where it appears and kept in CureCircle's evidence base with the source's own words. It is not medical advice. Read on 7 November 2026.

Iron-deficiency anaemia is common and often dismissed: tiredness, breathlessness, feeling cold, put down to a busy life until a blood test shows it. Finding the cause matters as much as treating it, and treatment itself can be hard, with tablets that upset the stomach and infusions that are not always offered. How long symptoms lasted, what the cause turned out to be, and what helped is what research on anaemia needs.

How many people it affects

The Global Burden of Disease study found that dietary iron deficiency remains a major health concern with a global prevalence of 16.7%, and that anaemia due to dietary iron deficiency made up 66.2% of all anaemia cases.

The records worth keeping

The British Society of Gastroenterology's guideline on iron-deficiency anaemia describes the tests that leave records:

• A ferritin blood test, the single most useful marker of iron deficiency.
• Tests for the cause, including a coeliac screen and a urine test, and for men and women after the menopause, a gastroscopy and colonoscopy.
• A check that treatment works: a haemoglobin check in the first 4 weeks of iron tablets.
• Blood counts afterwards, perhaps every 6 months initially, to catch it coming back.

A series of blood counts and ferritin results shows the whole course. If you do not have them, ask your practice for a copy.

What sharing it is worth

CureCircle values every contribution with a public benchmark built from what health data has sold for. A complete iron-deficiency anaemia story with the records the guideline lists comes to about $64 per licence on the benchmark today. Every line and its source is on the iron-deficiency anaemia page.

A licence is not a one-off sale: the same de-identified story can be licensed to several research teams, and you earn a share each time.

How to share it

You start by writing what you live with in your own words; a few quick questions follow, then an AI interviewer asks about the details only you know, and you rate every treatment you tried, from tablets to infusions. You can add blood results and letters as PDFs or photos, and the AI reads them into your own medical file. Before anything is shared, you read the de-identified summary and decide.
