Postpartum thyroid dysfunction (PPTD) occurs in 5\u20139% of women and is associated with antithyroid peroxidase antibodies (antiTPOAb) in 10% of women in early pregnancy. Therefore, screening for thyroid dysfunction in pregnancy should be considered. T4 and thyroid stimulating hormone measurements could be used to screen for hypothyroidism, which would require levothyroxine intervention treatment. T4 supply is crucial to fetal nervous system maturation; currently, the recommended daily iodine intake is 200 \u03bcg, and this is not always achieved, even in the UK. At present, a randomised prospective trial is ongoing to provide the evidence base for this screening strategy. Meanwhile, it is reasonable to (a) optimise iodine nutrition during pregnancy; (b) ascertain women with known thyroid disease; (c) identify women at increased risk of thyroid disease\u2014for example, those with other autoimmune diseases. PPTD can be predicted by measurement of antiTPOAb in early gestation.<\/jats:p>","DOI":"10.1136\/jcp.2004.021881","type":"journal-article","created":{"date-parts":[[2005,4,27]],"date-time":"2005-04-27T16:16:29Z","timestamp":1114618589000},"page":"449-452","source":"Crossref","is-referenced-by-count":77,"title":["<i>BEST PRACTICE NO 184<\/i>\n                    Screening for thyroid disease in pregnancy: \n            Table 1"],"prefix":"10.1136","volume":"58","author":[{"given":"J H","family":"Lazarus","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L D K E","family":"Premawardhana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2005,4,27]]},"reference":[{"key":"2025121220193628000_58.5.449.1","doi-asserted-by":"publisher","DOI":"10.1210\/er.18.3.404"},{"key":"2025121220193628000_58.5.449.2","doi-asserted-by":"publisher","DOI":"10.1097\/00003081-199703000-00004"},{"key":"2025121220193628000_58.5.449.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.beem.2004.03.005"},{"key":"2025121220193628000_58.5.449.4","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2265.2000.01087.x"},{"key":"2025121220193628000_58.5.449.5","doi-asserted-by":"publisher","DOI":"10.1016\/S1096-6374(03)00055-8"},{"key":"2025121220193628000_58.5.449.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.beem.2004.03.008"},{"key":"2025121220193628000_58.5.449.7","first-page":"13","volume":"5","year":"1993","journal-title":"Thyroidology"},{"key":"2025121220193628000_58.5.449.8","unstructured":"Burrow GN, Golden LH.
