There's generally no strict upper age limit for blood donation if you're an existing donor, but first-time donors often have a cutoff, like 75 or 76 years old, with requirements focusing on your overall health and a doctor's approval for older individuals. While some organizations, like the Red Cross (US), have no upper age limit as long as you're well, others, like Australia's Lifeblood, allow first-timers up to 75/76 but let regular donors continue well past 80, with some donors reaching their 90s.
Blood donation requirements
To donate blood, Lifeblood donors must: Be healthy and not suffering from a cold, flu or other illness at the time of donation. Be aged between 18 and 75 years (other rules may apply if you are a current donor). Weigh at least 50kg.
In general, as long as you are fit and healthy, weigh over 7 stone 12 lbs (50kg) and are aged between 17 and 66 (up to 70 if you have given blood before) you should be able to give blood. If you are over 70, you need to have given blood in the last two years to continue donating.
At age 92, blood donation requires careful evaluation of overall health and medical history. Older adults may face increased risks such as anemia or cardiovascular strain from donating. It is advisable to consult a healthcare provider before continuing blood donations.
There is no upper age limit for blood donation as long as you are well with no restrictions or limitations to your activities. Those younger than age 17 are almost always legal minors (not yet of the age of majority) who cannot give consent by themselves to donate blood.
The most needed blood types are O positive (O+) and O negative (O-), with O positive being needed most frequently because it's the most common and compatible with over 80% of the population, while O negative is the universal donor for emergencies when a patient's type is unknown. Hospitals constantly request O type blood, so donors with O+ and especially O- are critical to maintain supply.
In Australia, you generally cannot donate blood if you're unwell (cold, flu), have certain infections (like HIV, Hepatitis), have had recent tattoos/piercings (wait times apply), have recently travelled to high-risk areas, use certain medications (like anti-clotting drugs), have had specific medical treatments (like melanoma treatment), or have had recent sex with new partners or male partners in certain situations. Age limits also apply (18-60 for new donors, up to 75 for first-timers).
The rarest blood type in Australia, and globally, is Rh-null (Golden Blood), which lacks all Rh antigens and was first discovered in an Aboriginal Australian woman; among common types, AB-negative (AB-) is the rarest, found in about 1% of the population, though specific rare bloods linked to certain ancestries (like Polynesian or Indian) are also exceptionally scarce.
You must be in good health at the time you donate. You cannot donate if you have a cold, flu, sore throat, cold sore, stomach bug or any other infection. If you have recently had a tattoo or body piercing you cannot donate for 6 months from the date of the procedure.
The following medications will prevent you from donating blood:
AB negative is the rarest of the 8 main blood types. Demand is for AB negative is relatively low and thanks to our current donors we usually have enough to meet patient need.
Yes, donating blood is generally good for you, offering significant benefits like a healthier heart and vascular system (lower blood pressure/heart attack risk), reduced iron levels (which can lower cancer/liver disease risk), and emotional well-being (stress reduction, sense of purpose). It also provides a free mini-physical, revealing potential health issues through screening, and stimulates the body to create new blood cells.
To donate blood, you need to: be generally fit and well. be aged 17 to 65 if it's your first donation, or up to 72 if you've donated before (or older if you donate regularly) weigh between 7 stone 12 lbs (50kg) and 25 stone (158kg)
Maximum age for donation: 75 for first-time donors
You can become a first-time blood, plasma or platelet donor any time up until your 76th birthday (but you can only give platelets if you've given plasma before). Once you're 81 you must have donated in Australia in the last 5 years to remain eligible.
It is safe for individuals who have well-managed high blood pressure to give blood. Individuals are also not deferred for high blood pressure medication. The Red Cross only defers donors with blood pressure greater than 180/100 mmHg, when hypertension should be quickly addressed by a health care provider.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
An AB personality's negative traits can include being self-centered, irresponsible, vulnerable, indecisive, forgetful, unforgiving, and critical. Famous people with AB blood types include Barack Obama, Marilyn Monroe, Jackie Chan, and John F. Kennedy.
Aboriginal patients had a higher prevalence of ABO group O (59.8 % vs 43.9 %) and RhD positive (99.0 % vs 83.8 %).
Blood donation age limits vary by country, but generally, you must be at least 17 or 18 years old, with first-time donors often having a maximum age (like 75 in Australia, or 65 in the UK) while regular donors can continue past that age if they remain healthy. Key requirements include being in good health, meeting weight criteria (around 50kg/110lbs), and having no recent illnesses or certain risky behaviors, with specific rules for different donation types like plasma.
You do not get paid to donate blood or plasma in Australia; the system relies on altruistic, unpaid volunteers, unlike in some other countries where donors receive money, which Australia avoids to maintain its volunteer-based supply for ethical reasons, though this leads to reliance on imported plasma. While there's no money, donors may receive small gifts or rewards through the Australian Red Cross Lifeblood rewards program, like blankets or drink bottles, for consistent donations.
The most needed blood types are O positive (O+) and O negative (O-), with O positive being needed most frequently because it's the most common and compatible with over 80% of the population, while O negative is the universal donor for emergencies when a patient's type is unknown. Hospitals constantly request O type blood, so donors with O+ and especially O- are critical to maintain supply.
While the Bible doesn't mention Jesus's blood type, scientific analysis of relics linked to him, like the Shroud of Turin and Eucharistic miracle samples, consistently shows Type AB blood, a rare type, leading some to believe it's a miraculous sign, though skeptics point to potential bacterial contamination.
Ichor originates in Greek mythology, where it is the "ethereal fluid" that is the blood of the Greek gods, sometimes said to retain the qualities of the immortals' food and drink, ambrosia and nectar. Ichor is described as toxic to humans, killing them instantly if they came in contact with it.
O positive (O+cap O raised to the positive power𝑂+) blood is special because it's the most common type, can be given to over 70% of the population (anyone with a positive blood type like A+, B+, AB+, or O+cap O raised to the positive power𝑂+), and is crucial for emergency transfusions when a patient's type is unknown, though people with O+cap O raised to the positive power𝑂+ can only receive O+cap O raised to the positive power𝑂+ or O−cap O raised to the negative power𝑂− blood. Its widespread compatibility and commonality make it a workhorse for hospitals, especially in trauma care, but also means it's frequently in short supply.
