Blood group test in Chiswick
This blood test identifies your ABO blood group and your RhD status, positive or negative. People book it out of curiosity, before travel, for pregnancy planning, or to keep a personal record of their blood type.
What the test measures
Your blood group is determined by markers called antigens on the surface of your red blood cells. The ABO system sorts blood into A, B, AB or O, depending on which antigens are present. The Rh system adds whether you carry the RhD antigen, making you RhD positive or RhD negative. Together, these give the familiar groups such as O positive or A negative.
Blood group is inherited from your parents and stays the same throughout life. It matters most for blood transfusions and in pregnancy, when an RhD negative mother may carry an RhD positive baby. It is also useful to know if you are considering giving blood.
The price includes the blood sample at our Chiswick clinic, analysis at the Randox accredited laboratory, a practitioner review of your result and a GP feedback report on request.
Who it is for
- You would like to know your blood group for your personal records.
- You are planning a pregnancy and want to know your RhD status in advance of antenatal care.
- You are travelling or working abroad and want your blood group documented.
- You are curious about how your blood group relates to your family.
- You are thinking about becoming a blood donor.
Understanding your result
Your report states your ABO group and RhD status. O positive and A positive are the most common groups in the UK. O negative blood can be given to most people in an emergency, and AB positive people can receive red cells from most groups. Being RhD negative is not a health problem, but it matters in pregnancy because NHS antenatal care offers anti-D injections where needed to protect future babies.
Please be aware that hospitals always carry out their own blood group and compatibility tests before any transfusion, so a private result cannot replace these. There is no such thing as a good or bad blood group, and the result does not diagnose any condition.
Preparing for your test
No fasting or preparation is needed, and you can test at any time of day. If you have had a blood transfusion in the last three months, please tell us, as it can affect the result.
If you would like a general health picture at the same visit, a full blood count or our Omnia Essential check are good places to start. You can also see every blood test and price in Chiswick.
Questions
How much is a blood group test in Chiswick?
The Blood Group test costs £69 at Omnia Lifestyle in Chiswick. It includes the blood sample, accredited laboratory analysis, a practitioner review of your result and a GP feedback report if requested.
Can my blood group change?
No. Your blood group stays the same for life, except in very rare situations such as after a bone marrow transplant.
Can I use this result for a transfusion?
No. Hospitals always repeat blood group and compatibility testing themselves before any transfusion for safety.
Why does RhD matter in pregnancy?
If an RhD negative mother carries an RhD positive baby, her immune system may react in a later pregnancy. Midwives offer anti-D treatment to prevent this, so knowing your status helps planning.
