Blood Donation Eligibility Checker - Online Quick Questionnaire

Generally, donors must be at least 17 years old (16 in some regions with parental consent), weigh at least 110 lbs (50 kg), and be in good general health. You should not have any active infections, and must pass a mini-physical on the day of donation including hemoglobin, blood pressure, and temperature checks.

If you got a tattoo from a state-regulated, licensed facility using sterile needles, you may be eligible to donate after a waiting period of 3 to 12 months depending on your location. In some areas with strict regulation, there may be no waiting period. Tattoos from unregulated settings typically require a 12-month deferral.

Conditions that typically result in permanent deferral include: HIV/AIDS, Hepatitis B or C, certain types of cancer (especially blood cancers like leukemia or lymphoma), Creutzfeldt-Jakob disease, and certain heart conditions. Each blood donation organization maintains its own specific list of deferral criteria.

It depends on the medication. Many common medications like birth control, blood pressure medications, and cholesterol drugs are acceptable. However, certain medications such as blood thinners (anticoagulants), some acne treatments (isotretinoin), and certain antibiotics may require a waiting period or deferral. Always disclose all medications during your screening.

Travel to malaria-endemic areas typically requires a waiting period of 3 to 12 months, depending on the destination and duration of stay. Countries in sub-Saharan Africa, parts of South Asia, and certain tropical regions are common areas of concern. Check with your local blood center for specific travel-related deferrals.

For minor surgeries with no complications, you may be able to donate once fully recovered. For major surgeries, the waiting period is typically 6 to 12 months. If you received a blood transfusion during surgery, a 12-month deferral is standard in most countries.

No. If you are currently experiencing cold or flu symptoms, fever, or generally feel unwell, you should wait until you are fully recovered and symptom-free (typically for at least 48 hours after symptoms resolve) before donating blood. This protects both you and the recipient.

In many countries, there is no upper age limit for regular donors in good health. However, first-time donors over age 60 or 65 may be restricted in some regions. Each blood center evaluates older donors on a case-by-case basis, considering overall health and medical history.

Pregnant women are deferred from donating blood during pregnancy and typically for 6 weeks to 6 months after childbirth (longer if breastfeeding). This is to protect the mother's iron stores and overall health. Nursing mothers are usually deferred until the baby is significantly weaned.

For most routine vaccinations (flu, tetanus, COVID-19 mRNA vaccines), you can donate immediately as long as you feel well. For live attenuated vaccines (such as MMR, chickenpox, or yellow fever), a waiting period of 2 to 4 weeks is typically required. Always inform staff about recent vaccinations during screening.
