Do not eat, brush or floss teeth, use mouthwash, or chew gum for 1 hour before taking the 1 day oestrogen and progesterone test.
Please inform your practitioner about all medication, oral contraceptives and hormone supplements so that they may interpret your results correctly.
Use of transdermal cream and sublingual bio-identical hormones may produce artificially high levels in the saliva that do not correlate with blood levels. This increase may last for 2 weeks to a few months after discontinuing use. Please consult with your health care practitioner about the timing of this test if this applies to you.
