Laboratory studies that may be useful include the following:

  • Complete blood count

  • Iron studies (total iron-binding capacity [TIBC] and total iron)

  • Coagulation factor studies (expensive and to be used sparingly)

  • Human chorionic gonadotropin (hCG) level

  • Thyroid function tests and prolactin level

  • Liver function tests (LFTs), renal function tests (blood urea nitrogen [BUN] and creatinine), or both

  • Hormone assays (eg, luteinizing hormone [LH], follicle-stimulating hormone [FSH], and androgen) for suspected PCOS; adrenal function tests for suspected adrenal tumors
