The conditions screened for are:- Sickle cell anaemia (Hb SS), Hb SC disease, Hb S\/\u03b2-thalassaemia, Hb S\/D<jats:sup>Punjab<\/jats:sup>, Hb S\/O<jats:sup>Arab<\/jats:sup>, Hb S\/HPFH. Carriers identified for the common haemoglobin variants are reported to parents and follow-up counselling is offered. A bespoke laboratory quality assurance programme has been established which has defined standards of satifactory performance. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> Provisional figures from the first seven months of screening (up to March 2004) 108,255 infants were screened gave a screen positive rate of 1:900 for these high prevalence areas and a carrier rate of 2.7%. Figures for 2004-2005 show about 250 significant screen positive results for sickle cell disorders and about 6,500 carriers were identified. The birth prevalence for screen positive results from 2004-05 is 1:1500. We estimate that when there is countrywide data, the national birth prevalence will be about 1:2000-1:2,500. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p> The results from the national newborn sickle cell screening programme in England - show that the sickle cell disorders are as common as cystic fibrosis (CF) in England, although the distribution of cases is concentrated in London and other urban areas. The findings and approach to implementation adopted in England may be of interest to other Western European countries with increasing rates of sickle cell disease who are considering such programmes and also to other developed countries. <\/jats:p><\/jats:sec>","DOI":"10.1258\/jms.2008.007063","type":"journal-article","created":{"date-parts":[[2008,4,14]],"date-time":"2008-04-14T01:53:34Z","timestamp":1208138014000},"page":"9-13","source":"Crossref","is-referenced-by-count":37,"title":["Implementation of the newborn screening programme for sickle cell disease in England: results for 2003-2005"],"prefix":"10.1177","volume":"15","author":[{"given":"Allison","family":"Streetly","sequence":"first","affiliation":[{"name":"NHS Sickle Cell and Thalassaemia Screening Programme, Division of Health and Social Care Research, King's College London School of Medicine, 7th Floor Capital House, 42 Weston Street, London SE1 3QD, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mary","family":"Clarke","sequence":"additional","affiliation":[{"name":"Epsom and St Helier Hospital, Surrey, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Melanie","family":"Downing","sequence":"additional","affiliation":[{"name":"Regional Newborn Screening Laboratory, Sheffield Children's Hospital, Sheffield, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa","family":"Farrar","sequence":"additional","affiliation":[{"name":"St James's Hospital, Leeds, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying","family":"Foo","sequence":"additional","affiliation":[{"name":"Newborn Screening Laboratory, Great Ormond Street, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kate","family":"Hall","sequence":"additional","affiliation":[{"name":"Principal Biochemist, West Midlands Newborn Screening Centre, Birmingham Children's Hospital, Birmingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Helena","family":"Kemp","sequence":"additional","affiliation":[{"name":"Newborn Screening Laboratory, Southmead Hospital, Bristol, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jane","family":"Newbold","sequence":"additional","affiliation":[{"name":"King's College Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Walsh","sequence":"additional","affiliation":[{"name":"Alder Hey Children's Hospital, Liverpool, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jenny","family":"Yates","sequence":"additional","affiliation":[{"name":"Royal Manchester Children's Hospital, Manchester, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joan","family":"Henthorn","sequence":"additional","affiliation":[{"name":"Head of Haemoglobinopathy Laboratory, Central Middlesex Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2008,3,1]]},"reference":[{"key":"bibr1-jms.2008.007063","doi-asserted-by":"publisher","DOI":"10.1596\/978-0-821-36179-5\/Chpt-34"},{"key":"bibr2-jms.2008.007063","volume-title":"The March of Dimes Global Report on Birth Defects.
