  • Hyperpolactinemia pattern of lipid abnormalities, of course, is important because it is a risk factor for atherosclerotic cardiovascular disease. Because patients with subclinical hypothyroidism sometimes have subtle hypothyroid symptoms and may have mild abnormalities of serum lipoproteins and cardiac function, patients with definite and persistent TSH elevation should be considered for thyroid treatment.

  • Significant positive correlation between TSH and prolactin was noted in ScH and primary hypothyroidism.

  • Measurement of serum TSH is generally considered the best screening test for thyroid disease; increased values usually indicate hypothyroidism, and decreased values usually indicate hyperthyroidism.

  • Ross subclinical hypothyroidism. Preventive Services Task Force 2 has recommended that asymptomatic adults not be screened because evidence of clinical benefit is insufficient.
