Laboratory and Imaging Studies

Laboratory studies

Recommended laboratory studies are as follows:

  • Urine human chorionic gonadotropin

    • Urine human chorionic gonadotropin (hCG) findings become positive approximately 1 week after conception.

    • Perform the test on the day of surgery (preoperatively); it can detect hCG levels as low as 20 mIU/mL (International Reference Preparation).

    • Perform the test to rule out a luteal-phase pregnancy. Even if the test result is negative, the patient can possibly still be pregnant. For this reason, sterilization is best performed in the first few days of the menstrual cycle.

  • Papanicolaou test: A Papanicolaou test should be performed within 6 months of the procedure.

  • Urinalysis and hemogram: As per protocol of surgical unit

  • Gonorrhea and chlamydia screening: Sterilization using any technique is contraindicated in the presence of active pelvic infection.

Imaging studies

Ultrasonography is indicated when a pelvic mass is detected during the preoperative clinical examination or when a pelvic examination is inadequate (eg, in a patient with morbid obesity).
