Blood Group Blood Test
Your blood group is defined by different combinations of red blood cell antigens. This is determined by your genetic make-up. There are eight main blood groups: A positive and negative, B positive and negative, AB positive and negative and O positive and negative. This test examines your antigens to determine your blood group.
Why would I need to find out my blood group?
Common reasons for this blood test are:
- To make sure you know your correct blood group in a medical emergency, such as one requiring a blood transfusion
- For information during pregnancy
- If you are due to undergo surgery, and your doctor needs to know.
Your blood test
Our phlebotomy-trained professionals will take a blood sample from you. This sample will be analysed in the UK by our authorised partners, TDL. By booking this blood test, you agree for us to share your personal information with TDL in order to process your test. We’ll make sure you consent to this at your appointment too.
Frequently Asked Questions
No, we will send you the results and recommend that you share these with your GP or fertility provider.
It is not unusual for some bleeding to occur under the skin following your blood test and sometimes this can extend a little further around the puncture site. If this causes you concern, check with your practice nurse.
Sometimes we cannot get a blood sample from you. This can be for many reasons, such as not being hydrated enough, feeling cold or having another blood test recently. We will always offer you another appointment so we can try again.
