Yes and no. The answer is “No” when hormones are produced within the body (endogenously), or are slowly delivered into the body with a transdermal patch (e.g., estradiol patch) or by pellet insert. In these situations, hormone test results are remarkably similar from finger-stick dried blood spots and serum. In fact, hormone ranges established for blood spots are nearly identical to those of serum.
