• Rationale and Comments

    Amenorrhea is the absence of menstruation and can be attributed to many causes. A karyotype (chromosomal analysis) is not indicated as an initial test for amenorrhea as it is not a screening test. However, it is indicated to further evaluate the etiology of an elevated follicle-stimulating hormone in a woman under 40 years of age or in the presence of physical findings suggestive of disorders of sexual development.
