Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

The upper normal limit of serum prolactin is typically between 15 to 25 ng/mL for both genders. [1] Levels exceeding this range indicate hyperprolactinemia. Prolactin (PRL) is a peptide hormone produced by lactotroph cells in the anterior pituitary gland. [1] It plays a vital role in lactation and breast development. [1]
Prolactin is sometimes classified as a gonadotropin [17] although in humans it has only a weak luteotropic effect while the effect of suppressing classical gonadotropic hormones is more important. [18] Prolactin within the normal reference ranges can act as a weak gonadotropin, but at the same time suppresses gonadotropin-releasing hormone ...
The most common complex found in blood consists of prolactin and immunoglobulin G (IgG). [1] While the free prolactin hormone is active, prolactin in the macroprolactin complex does not have any biological activity in the body and is considered benign. [2] However, macroprolactin is detected by all Laboratory tests that measure prolactin in ...
For comparison, normal prolactin levels in women are less than 20 ng/mL, prolactin levels peak at 100 to 300 ng/mL at parturition in pregnant women, and in lactating women, prolactin levels have been found to be 90 ng/mL at 10 days postpartum and 44 ng/mL at 180 days postpartum. [77] [78]

Hypoprolactinemia can result from autoimmune disease, [2] hypopituitarism, [1] growth hormone deficiency, [2] hypothyroidism, [2] excessive dopamine action in the tuberoinfundibular pathway and/or the anterior pituitary, and ingestion of drugs that activate the D 2 receptor, such as direct D 2 receptor agonists like bromocriptine and pergolide, and indirect D 2 receptor activators like ...
