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.
