Salivary testosterone levels should range from 5 to 46 pmol/L for females and 93 to 378 pmol/L for males. (Keevil et al., 2014) The test results are highly sensitive to several factors, including age, medication, medical conditions, and the time of day and season that the test is collected. (Paduch et al., 2013)
