Endometrial Biopsy: Testing the Uterine
Lining for Cause of Recurrent Miscarriage
The endometrial biopsy is a test to determine the health of the uterine lining and its ability to
support a pregnancy in patients who suffer from recurrent loss.
The endometrial biopsy is performed after ovulation and just before the onset of menstruation. A
doctor will remove a small sample of tissue from the endometrium (the lining of the uterus).
With the aid of a microscope, a pathologist will later examine the lining for proper thickness
according to cycle dates and analyze the tissue for abnormal cells. In association with recurrent
loss, endometrial biopsy is performed to diagnose or rule out a luteal phase defect, the condition
in which the endometrium is not properly prepared for implantation of the fetus. However, the
test may also be performed in screening for cancer, analyzing the cause for abnormal vaginal
bleeding or testing for certain infections.
Preparing for the Biopsy
The patient has few requirements in preparing for the test. The procedure is much like a pap
smear. However, the patient may experience cramping during (and up to a day or two after) the
biopsy. The physician may recommend a dose of over-the-counter pain medication be taken prior
to the procedure and following, as needed. Additionally, due to the slight risk of disruption in a
potential pregnancy, the doctor may require a pregnancy test before the biopsy. The patient may
be asked to abstain from unprotected intercourse during the entire cycle prior to the test.
The biopsy will most likely take place in the doctor’s office. The test is quick and is generally
completed in under 10 minutes. The patient will be asked to disrobe from the waist down, after
which she will be directed to place her feet in stirrups. The doctor may perform a brief pelvic
exam and will then:
Insert a speculum into the vagina
Insert a small catheter through the cervix and into the uterus
Suction out a small sample of the uterine lining
Place the sample into a liquid preparation to send to the pathologist
After the Biopsy
The patient may experience light bleeding after the endometrial biopsy. Due to the timing of the
procedure, bleeding may last until the beginning of menstruation (which generally follows a day
or two after). The patient does not need to be concerned about bleeding, unless it becomes
heavier than normal menstruation. Heavy bleeding or a fever over 100° F elicits a call to the
practicing physician. Risks are very rare, but infection or other problems, such as damage to the
uterus or cervix, can occur.
Patients can expect results in about one week to one and a half weeks. Normal cells and proper
development of the lining for cycle dates indicate a healthy lining. If the development of the
lining is off by about two days or more (according to the actual cycle date), or if there are any
abnormal cells present, treatment or further testing may be required.
A physician may request a blood draw to analyze the patient’s progesterone levels in addition to
or instead of the endometrial biopsy. The doctor will test the levels during the post-ovulation
time period, during which the progesterone should be elevated (10 or more ng/ml). Low levels
of progesterone indicate a potential problem with the development of the endometrium.
However, there is debate that the endometrium may not respond to proper progesterone levels.
Thus, serum levels alone may not reveal a problem with the endometrium.
