Because the treatment is simple, effective, and inexpensive, most of the developed world utilizes newborn screening with blood thyroid stimulating hormone (TSH) levels to detect congenital hypothyroidism. Most children with congenital hypothyroidism correctly treated with thyroxine grow and develop normally in all respects.
Newborn screening (NBS) is a public ... Congenital hypothyroidism was the second disease widely added in the 1970s. [2] Guthrie and colleagues also developed ...
The following disorders are additional conditions that may be detected by screening. Many are listed as "secondary targets" by the 2005 ACMG report. [1] Some states are now screening for more than 50 congenital conditions. Many of these are rare and unfamiliar to pediatricians and other primary health care professionals. [1] Blood cell disorders
Congenital iodine deficiency has been almost eliminated in developed countries through iodine supplementation of food and by newborn screening using a blood test for thyroid function. [5] Treatment consists of lifelong administration of thyroxine (T4). Thyroxine must be dosed as tablets only, even to newborns, as the liquid oral suspensions and ...
Screening for hypothyroidism is performed in the newborn period in many countries, generally using TSH. This has led to the early identification of many cases and thus the prevention of developmental delay. [59] It is the most widely used newborn screening test worldwide. [60]
Thyroid dysgenesis is a cause of congenital hypothyroidism [1] where the thyroid is missing (thyroid agenesis), ectopic, or severely underdeveloped.It should not be confused with iodine deficiency, or with other forms of congenital hypothyroidism, such as thyroid dyshormonogenesis, where the thyroid is present but not functioning correctly.
Newborn screening mostly measures metabolite and enzyme activity using a dried blood spot sample. [99] Screening tests are carried out in order to detect serious disorders that may be treatable to some extent. [100] Early diagnosis makes possible the readiness of therapeutic dietary information, enzyme replacement therapy and organ transplants ...
Newborn screening: Newborn screening is conducted just after birth to identify genetic disorders that can be treated early in life. This testing of infants for certain disorders is one of the most widespread uses of genetic screening - all US states currently test infants for phenylketonuria and congenital hypothyroidism. US state law mandates ...
