Volume of red cells in capillary blood varies from that of venous blood. The magnitude of this variation as well as its impact on the diagnosis of anaemia in pregnancy needs to be studied. This study demonstrates the disparity between capillary and venous PCV in pregnancy.
To determine whether capillary blood PCV (cPCV) differed from venous blood PCV (vPCV) of normal pregnant women in Enugu, Nigeria, and its effect on diagnosis and prevalence of anaemia.
PCV was estimated using pairs of venous and capillary blood samples from 200 consecutive pregnant women at the Antenatal Clinic of University of Nigeria Teaching Hospital, Enugu, Nigeria.
Participants' cPCV (median = 34.0%, IQR = 31.0-35.8) was significantly lower than their vPCV (median = 34.0%, IQR = 32.0-37.0) (Z = -6.85, P < 0.001). However, women's cPCV had strong positive correlation with their vPCV (r = 0.883, P < 0.001). The prevalence of anaemia among participants using capillary and venous blood was 33.5% (67/200) and 28.0% (56/200), respectively (O.R = 1.3 (CI 95%: 0.85, 1.98), P = 0.233).
Capillary blood PCV was lower than vPCV among pregnant women in Enugu, Nigeria. Nevertheless, the prevalence of anaemia derived from cPCV did not differ significantly from that of vPCV.
毛细血管血红细胞容量与静脉血红细胞容量不同。这种变化的幅度及其对妊娠贫血诊断的影响需要研究。本研究显示了妊娠期间毛细血管血和静脉血 PCV 之间的差异。
确定尼日利亚埃努古的正常孕妇的毛细血管血 PCV(cPCV)是否与静脉血 PCV(vPCV)不同,以及其对贫血诊断和患病率的影响。
使用尼日利亚埃努古大学教学医院产前诊所的 200 名连续妊娠妇女的静脉和毛细血管血样本对 PCV 进行估计。
参与者的 cPCV(中位数=34.0%,IQR=31.0-35.8)明显低于 vPCV(中位数=34.0%,IQR=32.0-37.0)(Z=-6.85,P<0.001)。然而,女性的 cPCV 与 vPCV 呈强正相关(r=0.883,P<0.001)。使用毛细血管和静脉血的参与者贫血患病率分别为 33.5%(67/200)和 28.0%(56/200)(O.R=1.3(95%CI:0.85,1.98),P=0.233)。
尼日利亚埃努古的孕妇毛细血管血 PCV 低于静脉血 PCV。然而,源自 cPCV 的贫血患病率与 vPCV 无显著差异。
