| Signs and tests: |

Traditionally, a biopsy of the endometrium is the standard for diagnosing luteal phase defect. However, measuring the progesterone level in blood serum is often used as a means of diagnosis instead of endometrial biopsy due to the pain, difficulties of precise menstrual cycle dating, and expense associated with endometrial biopsy. A blood serum progesterone level of lower than 10ng/mL one week prior to the start of menstruation or 7 days after the LH (luteinizing hormone) surge is generally accepted as a diagnosis of luteal phase defect. |
