results we included 66 eligible studies. the pooled prevalence of hbsag in blood donors of both emro and middle eastern (e and m) countries was 2.03% (95% confidence interval [ci]: 1.79 – 2.26). in addition, the prevalence rates in the emro countries was 1.99% (95% ci: 1.84 – 2.14) and 1.62% in the middle eastern countries (95% ci: 1.36 – 1.88). the prevalence among blood donors with more than ...

CLINICAL CHEMISTRY, Vol. 33, No. 1, 1987 189 tubes containing 200 ML of 0.6 mol/L HC1O4; thus deproteinization was instantaneous. The tubes were centrifuged within 1 h and the clear protein-free supernate was stored at 4 #{176}C until assayed. Such deproteinized samples were stable for at least two months at 4 #{176}C and were analyzed without prior neutralization. Lactate was measured with an ...

each country faces a continuing challenge to collect enough blood to meet the national needs. according to who, there should be at least 20 blood donations per 1,000 population for developing countries, in kazakhstan this indicator was only 16.8 in 2011. thus, we conducted an epidemiological assessment and drew a map of the regional distribution of blood and plasma donations in kazakhstan durin...
