What to expect
During your test, you will be asked to fill out a medical questionnaire to make sure you are well enough for the test. The main part of your screen will be a simple venous blood test (where blood is drawn from a vein in your arm using a needle). This should only take a minute or two to complete.
You would receive your results via email with the in-house GP's review to allow you to understand your results.
When do I get my results?
You will receive your results on the two days after the blood sample is taken as the sample is received by the laboratory the following day.
London laboratory test all samples as quickly as possible after receiving them which enables the team of in-house GPs to review and communicate your results in the fastest possible time frame.
