Medical review and sources
How we review the medical information in Jiwark’s tools against recognised international references, and each tool’s sources.
The references we rely on
- World Health Organization (WHO): Guidelines on selecting blood donors and assessing their suitability.
- American Red Cross: Eligibility requirements, and the interval for each type of donation.
- UK Blood Transfusion Services (JPAC): Donor selection guidelines and donation frequency.
- MSD Manuals: A plain-language medical explanation of blood donation, in Arabic.
- MedlinePlus (US National Library of Medicine): Blood typing, and Rh incompatibility in pregnancy.
How do we review the content?
- We check every rule and number in the tools against the references above, and list each tool’s sources at the end of its page.
- When a rule differs between countries we give the range, and never present one country’s rule as the only one.
- We review again at least every 12 months, and whenever a known rule changes, and update the review date on each tool.

A review does not replace an examination: the doctor at the donation centre always makes the final decision. Editorial policy
