Females should have salivary testosterone levels of 5–46 pmol/L and males should have salivary testosterone levels of 93–378 pmol/L. (Keevil et al., 2014)

These numbers are highly sensitive to several factors, like age, medication, medical conditions, and the time of day and season when the test is taken. (Paduch et al., 2013)
