Endometrial Biopsy Sugar Land, TX
What is an endometrial biopsy?
An endometrial biopsy is a procedure in which a tissue sample is obtained from the endometrium (the inside lining of the uterus) and is then observed under a microscope. The tissue is thoroughly examined for any cell abnormalities or cancer. The test also helps determine the cause of abnormal menstrual periods and can be used to screen for endometrial cancer.
How the Test is Performed
- The cervix is cleaned with an antiseptic solution.
- The cervix may then be gently grasped with an instrument to hold the uterus steady. Another instrument may be needed to gently stretch the cervical opening if there is tightness.
- An endometrial catheter is gently passed through the cervix into the uterus to collect the tissue sample.
- The tissue sample and instruments are removed. The tissue is sent to lab where it is examined under the microscope
- The procedure can be done without anesthesia
