RESUMO
The United Arab Emirates National Screening Programme for Congenital Hypothyroidism was established in January 1998. The programme measures neonatal thyroid-stimulating hormone [TSH] levels of blood samples collected on filter paper on day 5 by heel prick. The prevalence of raised TSH levels [> 5 microU/mL whole blood] during 1998 and 1999 was used to evaluate the degree of iodine-deficiency disorders [IDD] in the population in different regions. The ratio of TSH profile in the present study and goitre rate in schools in a 1994 study were discrepant, although there was good correlation between the ratio of TSH profile and urinary iodine. The prevalence of raised TSH levels was < 3% in the Emirates overall, which is normal, and IDD varied from mild to normal problems in different regions
