It depends on what you're testing.
B Complex/Bioton/hair and nail supplements or any supplement containing biotin should be stopped for 7 days before any blood test.
If you take iron tablets and are testing iron these should be stopped 7 days before iron test.
Anything else you can take up to and including the day before the test and on the day of the test you take them after you've done the test. This gives you a measure of what your supplements are achieving for your Vit D, Folate or whatever you are testing.
