Check the test request
Take the request from your clinician and confirm the exact test names with the laboratory. Some blood tests require fasting; others do not. Follow the instructions for your tests and ask before changing any medicine.
At the appointment
A healthcare professional usually takes a small sample from a vein in your arm. Tell them if needles make you anxious or you have felt faint during a previous blood test.
Getting the report
Ask when the report will be ready and how you will receive it. Arrange for the clinician who requested the test to explain the results in the context of your symptoms and medical history.
