A venous blood sample means that blood is taken from a vein in your arm. Although a lot of our tests can be conducted on a finger-prick sample, there are many tests where the laboratory needs more blood and therefore a venous sample. You can arrange to have a venous sample taken at one of our partner clinics or have a nurse visit you at your home or office. If you know a suitably qualified person then you can make your own arrangements to have a venous blood sample taken. All these options will be available for you to choose from when you buy your test.
