Can O Negative donate to Rh negative?

Only 9% of the population has Type O- blood, yet it is the blood type in the highest demand. Type O- donors can help change the world by donating double red cells (an apheresis procedure that takes twice as many red blood cells).

To recruit people with Rhesus negative blood as regular donors, ensuring an adequate and safe blood supply in Hong Kong.

Introduction

The Rhesus (Rh) blood group system is another important blood group system after ABO. The Rhesus factor is a protein that is present (or absent) on the surface of red blood cells. People who have the Rhesus factor are considered to have a “positive” blood type and those don’t are considered to have a “negative” blood type, while negative blood causes no harm to your health.

Only 1 in 370 Chinese typed are Rh negative. A person with Rhesus 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 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.

Your family members may also have this negative blood type

Blood groups are inherited, so it is possible that other members of your family, especially siblings, may have the same blood type. We strongly encourage you to invite your family members to donate blood and bring along the invitation card enclosed to our blood donor centres or call us at 27101201 / 27101243 to make an appointment.

Why is one type of donation better for my blood type than another? Expand

Based on patient transfusion needs and the properties of your blood type, it is true that some donation types can make a bigger impact than others.  Read below to find out why.  Please note that this information is what is generally needed by patients.  Our inventory fluctuates every day based on patient needs, and we may occasionally ask donors to change their donation type to match our current needs.

Ideal Blood Types for Double Red Cell Donation: O-, O+, A-, B- Expand

There are some blood types that are used more frequently for transfusions that others because of their compatibility with the recipient’s blood type.  Donated red cells MUST be compatible with the recipient patient’s blood type in order for the transfusion to be successful.  If you check the chart above, you will notice that each of these blood types can be received by patients with a variety of blood types.  For this reason, we request donors with the blood type of O-, O+, A- or B- donate double red cells if they are eligible or a whole blood donation to make the maximum impact for our patients.

Ideal Blood Types for Platelet Donation: A+, B+, AB+, AB- Expand

Platelets are not as type specific as red blood cells, meaning that most patients can accept platelets from donors with any blood type, regardless of the patient’s blood type.  Since platelets only last for FIVE days, they are always needed by patients.  For this reason, we request donors with the blood type of A+, B+, AB+, or AB- to donate platelets if they are eligible or whole blood donation to make the maximum impact for our patients.

Ideal Blood Types for Plasma Donation: AB+ or AB- Expand

AB is the universal blood type for plasma donations, so we ask donors with the blood type of AB+ or AB- to donate plasma if they are eligible, to make the maximum impact for our patients.

Ideal Blood Types for Whole Blood Donation: All Types! Expand

We gladly accept whole blood donations from eligible donors with any blood type.  All donated blood and blood components makes a huge difference for patients in need.
