CPT® Code 83002

The CPT® Code 83002 refers to the testing of luteinizing hormone (LH), which is a type of gonadotropin. Gonadotropins are hormones produced by the pituitary gland that play a crucial role in the growth and functioning of the gonads, which are the sex organs responsible for reproduction. LH, along with follicle stimulating hormone (FSH), is essential for the development of eggs in females and sperm in males. These hormones are vital for the regulation of various reproductive processes and the development of secondary sexual characteristics, such as voice changes, muscle growth, hair distribution, and breast development. In females, LH and FSH work synergistically to stimulate the maturation of the graafian follicle and trigger ovulation. In males, LH is responsible for stimulating testosterone production, while FSH is involved in promoting sperm production. Testing for serum levels of LH and FSH is commonly performed to evaluate infertility issues in both men and women, investigate menstrual irregularities, diagnose disorders related to the pituitary gland, and assess conditions affecting the ovaries or testes. Additionally, these hormone levels can help diagnose cases of delayed or precocious puberty. The measurement of urine LH levels is particularly useful for detecting the surge in LH that occurs during ovulation. The testing for both serum FSH and LH levels is typically conducted using an electrochemiluminescent immunoassay, a sensitive and specific laboratory technique.
