Results of tests and investigations

We will contact you by text or telephone if a result is abnormal and you require treatment, or further investigations.  You will not be generally be contacted if your result is normal; however, we would encourage you to use the online system so that you are aware of your results.

Blood, urine and stool test results, as well as some x-ray and scan results are visible on your online medical record. If you have online access you can use the NHS App to view your results

If you are unable to use the online system, you can enquire about your result by telephone.  Please try to call in the afternoon so that you do not have to wait, as our phones are busiest in the mornings.  Our receptionists will tell you if your results is normal or, if the GP has indicated a follow up conversation is needed, the receptionist will arrange a telephone consultation with the GP who requested the test, during their next available surgery.   This is to ensure that you are speaking to the GP who knows your situation. If you wish to have further information about specific test results and what they mean, you can use this link:
