Reference Range

New reference range effective 6/22/2021

Males:  0.57 - 12.07 mIU/mL

Females:
     Premenopausal  0.56 - 89.08 mIU/mL

     Postmenopausal 5.16 - 61.99 mIU/mL 

Reference ranges for children not established in the laboratory.  

Limitations:  Heterophilic antibodies in human serum can react with reagent immunoglobulins, interfering with in vitro immunoassays.  Patients routinely exposed to animals or animal serum products can be prone to this interference and anomolous values may be observed.  Administration of gonadotropin-releasing hormone (GnRH), clomiphene citrate, and human menopausal gonadotropin (hMG) to females can results in elevated endogenous LH values, while administration of estrogens or testostersone can result in decreased endogenous LH values.  Administration of hMG to males can result in elevated endogenous LH values, while administration of testosterone decreases endogenous LH values.
