Most of such cases have iron deficiency anaemia. However, in Pakistan about 5% of the individuals with a hypochromic and microcytic blood picture have the \u03b2-thalassaemia trait. These individuals are more than often in a positive iron balance. However iron deficiency (being common) may be associated with the \u03b2-thalassaemia trait. This study of serum ferritin levels was carried out on 135 confirmed cases of the \u03b2-thalassaemia trait. A ferritin assay was done by a radioimmunoassay technique. The results show that the level of serum ferritin in 100 (74%) cases was within normal limits, in 17 (12.6%) cases it was above the normal range, whereas in 18 (13.4%) cases the level was lower than normal. The importance of serum ferritin estimation in carriers of the \u03b2-thalassaemia trait is highlighted.<\/jats:p>","DOI":"10.1159\/000203963","type":"journal-article","created":{"date-parts":[[2009,2,18]],"date-time":"2009-02-18T15:14:43Z","timestamp":1234970083000},"page":"7-9","source":"Crossref","is-referenced-by-count":9,"title":["Serum Ferritin Levels in Carriers of \u03b2-Thalassaemia Trait"],"prefix":"10.1159","author":[{"given":"Tanveer Zia","family":"Qureshi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masood","family":"Anwar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suhaib","family":"Ahmed","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dilshad Ahmed","family":"Khan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammad","family":"Saleem","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2009,2,18]]},"container-title":["Acta Haematologica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/203963","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000203963","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T11:41:01Z","timestamp":1777462861000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000203963"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,2,18]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000203963","archive":["Portico"],"relation":{},"ISSN":["0001-5792","1421-9662"],"issn-type":[{"value":"0001-5792","type":"print"},{"value":"1421-9662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,2,18]]}}}
