CPT® Code 82671

The CPT® Code 82671 refers to a laboratory test that quantifies the levels of fractionated estrogens in the blood, specifically measuring estradiol and estrone separately, while also calculating the total estrogen amount. Estrogens are a group of hormones that play a crucial role in the development and regulation of the female reproductive system and secondary sexual characteristics. The three primary estrogens measured in this test are estradiol, estriol, and estrone. A blood sample is collected through venipuncture, which is a standard procedure for obtaining blood for laboratory analysis. The test can be performed on either plasma or serum samples. The measurement of fractionated estrogens is particularly important for diagnosing various conditions related to hormonal imbalances. For instance, it can help identify precocious or delayed puberty in girls, assess disorders of sex steroid metabolism, and evaluate bone mineral density. Additionally, this test is instrumental in monitoring hormone replacement therapy in post-menopausal women, evaluating conditions such as hypogonadism and oligo-amenorrhea, and assessing ovarian function, including follicle development for assisted reproductive technologies like in-vitro fertilization. The methodology for measuring estradiol varies based on the patient's demographic; it is typically assessed using chemiluminescent immunoassay for pre-menopausal women, while tandem mass spectrometry is employed for males, children, and post-menopausal women. Estrone is also measured using tandem mass spectrometry, and the total estrogen level is derived from these measurements. In contrast, CPT® Code 82672 encompasses the measurement of total estrogens, which combines the values of all three estrogens into a single reportable figure. This total estrogen measurement is particularly useful for diagnosing estrogen-producing ovarian tumors in both pre-menarche and post-menopausal females, as well as for evaluating elevated estrogen levels in males. Furthermore, it can assist in determining the timing of ovulation, which is critical for optimizing conception efforts.
