What does a low result mean?

A lower reading is typical with hormonal birth control or temporary lifestyle stress shifting cycle rhythms.

What does a high result mean?

A sharp mid-cycle LH surge is the natural, healthy indicator that ovulation is occurring within 24 to 36 hours.

Questions ready for your doctor

Bring these questions to your next consultation to discuss with your healthcare practitioner:

  • Does this elevated value indicate my fertile ovulatory window?
  • Is the LH-to-FSH ratio informative for my assessment?
  • Would tracking this across subsequent cycles be helpful?
