Testosterone is most accurately measured in the morning, more specially before 11:00am. Testosterone is highest in morning and then declines throughout the day. Measuring serum testosterone in the morning allows a physician to observe your highest peak serum testosterone value. Serum testosterone declines throughout the day unless you engage in physical activities that will raise serum testosterone levels. A total testosterone value less than 300ng/dL is considered a reasonable cut off for men to be diagnosed with having Low-T.
