We are registered with a small village GP practice which is part of a group of five sister practices. It used to be the policy of our NHS trust that GP blood draws were carried out at the phlebotomy department of our nearest hospital, around 6 miles away - so we had to travel there and there was often a three week wait for an appointment.
Then the policy for this Trust area changed and blood draws were done at GP surgeries by practice nurses or phlebotomists.
Then the policy changed again and our surgery stopped doing blood draws other than for the very elderly and those who can't travel and if blood tests are ordered by our GPs, we now have to travel to one of the four sister practices to have these done. Since we live just one minute from the surgery this is very annoying. Hugely inconvenient also for those with no transport.
In none of these venues can I recall a nurse or phlebotomist asking any clinical questions, other than confirming name and date of birth. If a starving cholesterol test was being done at the hospital, they would ask you to confirm that you had not eaten since the night before.
Our GPs complete the request form for blood tests electronically and these are accessed by whichever practice we have booked the blood draw appointment with. The request forms include brief notes on the patient's presenting symptoms, any long-term or current diagnoses plus the names of any medications the patient is taking that might potentially affect blood test results. These notes can be seen if you ask for a print out or PDF of your test results.
The practice nurses or phlebotomists have never asked questions and added responses to the form that goes down to the hospital labs other than name and DOB.
If you have a practice where the practice nurse or nurse practitioner is permitted to order blood tests and do the draw, herself, then yes, they would likely ask you some questions in order to complete the form if the GP has not completed the blood test referral form,
