Testosterone as a Fasting Blood Test?

Mark A. Moyad, MD, MPH, the Jenkins/Pokempner Director of Preventive/Complementary and Alternative Medicine (CAM) at the University of Michigan Medical Center in the Department of Urology in Ann Arbor, Michigan, and Martin M. Miner, MD, Co-Director of the Men’s Health Center and Chief of Family and Community Medicine for Miriam Hospital, and Clinical Professor of Family Medicine and Urology at the Warren Alpert Medical School of Brown University in Providence, Rhode Island, discuss recent guidance suggesting that a fasting blood test is needed for testosterone. Dr. Moyad begins by explaining that in 2018, the Endocrine Society Clinical Practice Guidelines included a recommendation of measuring fasting morning testosterone. He suggests that this is a logical recommendation since, in a subset of men, testosterone levels may be temporarily lowered by food intake, but notes that this guidance does not appear to be widely known or followed. Dr. Miner says that he actually does usually include testosterone with other morning fasting tests to meet the demands of insurance, although he argues that this may also result in inaccurate levels since testosterone is supposedly at its peak in the afternoon. He also mentions that the American Urological Association does not recommend getting testosterone tested in a fasting specimen, although he is unsure why this is. Dr. Moyad concludes that this is a topic that is just beginning to be explored and should be watched.
