Testing hormones can be a valuable tool to confirm the cause of certain symptoms associated with hormonal shifts. These can include but are not limited to fibrocystic breasts, PMS, menopausal symptoms as well as male issues regarding libido, hair loss, muscle loss, energy and stress. Salivary hormone testing is less invasive than serum tests since no needles are involved, are less expensive, and are more representative of the bioavailable fractions of hormones.
