For a local Chinese, the chance is about 1 in 370, but Caucasians (e.g. Europeans, Americans, Australians etc.) have a much higher incidence of negative blood about 1 in 7.
A person with Rhesus(D) negative blood cannot receive positive blood. Since it is relatively rare, it is vital the Blood Transfusion Service maintains sufficient stocks of negative blood to ensure supply. Furthermore, Rhesus(D) positive patients can receive negative blood: O negative is know as the Universal Donor as it is compatible with all blood groups. This makes O Negative very special and widely used, especially in an emergency when minutes count.
The easiest way is to visit one of our centres and donate a unit of blood. You will be surprised how easy it is.
We would ask that you donate blood on a regular basis, or if you prefer, add your name to our register, so we can call upon you when there is a demand or emergency for your blood type.
We still need you! Rhesus(D) positive blood, being the most common, is always in demand and the Blood Transfusion Service needs at least seven hundred units a day to supply to Hong Kong hospitals. We are convinced that once you realize how simple and worthwhile giving blood is, you will become a regular donor.
As well as the feel good factor you get from giving blood, you will be secure in the knowledge that, should you, or your family, require a blood transfusion, it will be readily available. Remember blood is available free of charge in Hong Kong because our donors give their blood voluntarily.
