How to Prep for Hormone & Vaginal Labs to Avoid Invalid Results
When it comes to hormone or vaginal testing, timing and preparation can make or break your results. Improper prep can lead to false readings, unnecessary re-testing, and delays in your care plan. The good news? A few simple steps can ensure your labs are accurate and helpful from the start.
⏰ Timing Matters — Especially for Hormones
Hormone levels fluctuate throughout the day and month. Here’s how to plan:
Reproductive-Age Women: Test on Day 19–21 of your menstrual cycle for the most accurate snapshot of progesterone and estrogen levels.
Postmenopausal or Irregular Cycles: Testing can be done at any time, but your provider may advise retesting during specific symptoms for clarity.
Cortisol or Adrenal Testing: These are best done in the early morning (before 9 AM) when cortisol is naturally highest.
❌ What to Avoid Before Your Lab
Supplements: Avoid biotin, DHEA, and hormone supplements (like progesterone, estrogen, or testosterone) for 48–72 hours before your blood draw unless instructed otherwise.
Sexual Activity: Avoid intercourse or use of vaginal products like lubricants, suppositories, or creams for at least 24–48 hours before vaginal swabs or pH testing.
Vaginal Washing or Douching: Avoid all forms of internal cleansing prior to testing — it alters your natural flora and pH.
Heavy Exercise: Skip intense workouts the day before and morning of hormone bloodwork, as this can spike cortisol or skew thyroid levels.
Topicals or Lotions: If you're doing a skin patch test or saliva sample, skip makeup, lotions, or skincare near the collection site.
💧Hydrate — But Don’t Overdo It
Drink enough water to be well-hydrated (especially for bloodwork), but avoid overhydration which can dilute some results.
📝 Final Tips for Smooth Testing
Bring your lab order and ID.
Arrive on time and well-rested.
Tell your provider or lab technician about any recent infections, antibiotics, or abnormal bleeding.
