Early diagnosis and treatment of primary polycythaemia will significantly reduce the morbidity and mortality associated with this condition. Patients with a raised packed cell volume are divided into those with a raised red cell mass (absolute polycythaemia), and those with a red cell mass within their normal range (apparent polycythaemia). A standard investigative approach of an absolute polycythaemia enables patients with primary and secondary polycythaemia to be identified, leaving a group termed idiopathic erythrocytosis. There are a number of physiological situations and pathological events associated with idiopathic erythrocytosis and apparent polycythaemia. Careful follow-up of both groups of these patients is essential to identify possible causative mechanisms.<\/jats:p>","DOI":"10.1136\/pgmj.72.851.519","type":"journal-article","created":{"date-parts":[[2008,12,29]],"date-time":"2008-12-29T16:49:00Z","timestamp":1230569340000},"page":"519-524","source":"Crossref","is-referenced-by-count":4,"title":["Investigation of patients with polycythaemia"],"prefix":"10.1093","volume":"72","author":[{"given":"T C","family":"Pearson","sequence":"first","affiliation":[{"name":"Division of Haematology, United Medical and Dental Schools of Guy\u2019s and St Thomas\u2019s Hospitals, St Thomas\u2019 Hospital , Lambeth Palace Road, London SE1 7EH , UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Messinezy","sequence":"additional","affiliation":[{"name":"Division of Haematology, United Medical and Dental Schools of Guy\u2019s and St Thomas\u2019s Hospitals, St Thomas\u2019 Hospital , Lambeth Palace Road, London SE1 7EH , UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[1996,9,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"183","DOI":"10.1002\/bjs.1800600305","article-title":"The arterial complications of polycythaemia vera","volume":"60","author":"Barabas, A.P.; Offen, D.N.; Meinhard, E.A.","year":"1973","unstructured":"Barabas AP, Offen DN, Meinhard EA.
