Do I need to fast before taking the test?

Yes. Collect your sample first thing in the morning, before breakfast, after at least 8 hours of overnight fasting, as eating can affect your hormone levels and skew your results. You can drink water beforehand to help your blood flow. If you've already eaten, don't worry the kit has a one-year shelf life, so you can simply wait until next month. If you've already sent back a sample taken after eating, contact Customer Care.
