WHAT IS THYROID-STIMULATING HORMONE, FILTER PAPER TEST?
Thyroid screening is recommended for all newborns from birth to up to 4 weeks. With congenital hypothyroidism, TSH levels will be elevated. Test kits using filter paper are considered specific enough to use for screening purposes. Early detection of congenital hypothyroidism enables treatment and prevents complications, which include mental retardation and subnormal growth patterns.
