In Cameroon, these data are not yet available. Moreover, there is great variation in baseline parameters pertaining to full blood cell count among medical laboratories.Objectives: This study aimed to determine values for the complete blood cell count of a healthy adult Cameroonian population for use in locally derived ranges in our medical laboratories.Methods: A cross-sectional study was conducted among blood donors attending three blood banks in Yaound\u00e9 from November 2015 to September 2016. We expected to obtain at least 120 venous blood samples from both men and women. Tests were performed for (1) HIV, (2) complete blood cell count, (3) hepatitis B virus, (4) malaria, (5) syphilis, (6) C-reactive protein and (7) hepatitis C virus.Results: We enrolled 294 healthy participants (161 men, 133 women) aged 18 to 55 years. The median haemoglobin concentration was 135 g\/L in men and 114 g\/L in women (p  0.001). The median reticulocyte count was 60 \u00d7 109\/L in men and 40 \u00d7 109\/L in women (p  0.001). Significant variation by sex was observed for the platelet count. The median white blood cell count was 4.1 \u00d7 109\/L in men and 4.6 \u00d7 109\/L in women (p = 0.008).Conclusion: This study provides locally derived ranges for complete blood cell and reticulocyte counts for a healthy adult population in Yaound\u00e9, Cameroon. These results can be used pending larger studies.<\/jats:p>","DOI":"10.4102\/ajlm.v8i1.852","type":"journal-article","created":{"date-parts":[[2019,10,31]],"date-time":"2019-10-31T12:43:22Z","timestamp":1572525802000},"source":"Crossref","is-referenced-by-count":6,"title":["Haematological values in a healthy adult population in Yaound\u00e9, Cameroon"],"prefix":"10.4102","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0310-3972","authenticated-orcid":false,"given":"Martin E.","family":"Oloume","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9445-1309","authenticated-orcid":false,"given":"Abas","family":"Mouliom","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6469-6324","authenticated-orcid":false,"given":"Bernard F.","family":"Melingui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6072-2257","authenticated-orcid":false,"given":"Suzanne","family":"Belinga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0551-6789","authenticated-orcid":false,"given":"Julie S.","family":"Nana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1420-9628","authenticated-orcid":false,"given":"Mathurin","family":"Tejiokem","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3587-2848","authenticated-orcid":false,"given":"Francoise N.","family":"Sack","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6108-3140","authenticated-orcid":false,"given":"Jeanne","family":"Manga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5524-123X","authenticated-orcid":false,"given":"Annie R.","family":"Epote","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2580","published-online":{"date-parts":[[2019,10,31]]},"reference":[{"key":"ref0001","first-page":"160","volume":"41","author":"Koram","year":"2007","journal-title":"Ghana Med J"},{"key":"ref0002","author":"ANAES","journal-title":"Lecture critique de l\u2019h\u00e9mogramme: valeurs seuils \u00e0 reconna\u00eetre comme probablement pathologiques et principales variations non pathologiques"},{"key":"ref0003","doi-asserted-by":"crossref","first-page":"1802","DOI":"10.1093\/clinchem\/48.10.1802","volume":"48","author":"Hom","year":"2002","journal-title":"Clin Chem"},{"key":"ref0004","author":"CLSI","year":"2008","journal-title":"Defining, establishing, and verifying reference intervals in the clinical laboratory; approved guideline"},{"key":"ref0005","first-page":"198","author":"Bain","year":"2002","journal-title":"Blood cells \u2013 A practical guide"},{"key":"ref0006","doi-asserted-by":"publisher","DOI":"10.1093\/ajcp\/74.6.765"},{"key":"ref0007","first-page":"5","volume":"10","author":"Kueviakoe","year":"2011","journal-title":"ISRN Hematol"},{"key":"ref0008","doi-asserted-by":"publisher","DOI":"10.1111\/j.1751-553X.2008.01087.x"},{"issue":"1","key":"ref0009","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1128\/CDLI.11.1.29-34.2004","volume":"11","author":"Lugada","year":"2004","journal-title":"Clin Diagn Lab Immunol"},{"issue":"3","key":"ref0010","doi-asserted-by":"crossref","first-page":"443","DOI":"10.1128\/CDLI.10.3.443-445.2003","volume":"10","author":"Menard","year":"2003","journal-title":"Clin Diagn Lab Immunol"},{"key":"ref0011","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0036308"},{"issue":"5","key":"ref0012","first-page":"61","volume":"72","author":"Troussard","year":"2014","journal-title":"Ann Biol Clin"},{"key":"ref0013","author":"Comit\u00e9 r\u00e9gional de l\u2019Afrique, 56","year":"2006","journal-title":"La dr\u00e9panocytose dans la r\u00e9gion Africaine: Situation actuelle et perspectives.
