献血者献血量该如何确定,《献血者健康检查要求》中没有明确规定,只是简单要求体重:男≥50kg,女≥45kg;Hb男性≥120g/L,女性≥115g/L即可献血。人体血液总含量占到人体重的7%~8%,与体重在一定程度上呈正比。由于不同体重(w)、体重指数(BMI)、身高/体重(体型)的献血者体内总血量明显不同,这导致献血者可以捐献的血量不同。有报道称总血量与献血反应的发生有非常高的相关性〔1〕,体重越重献血反应的发生率越 Blood donation blood donation how to determine, “blood donors health check requirements” is not clearly defined, simply asking for weight: male ≥ 50kg, female ≥ 45kg; Hb men ≥ 120g / L, women ≥ 115g / L to donate blood. The total amount of human blood accounts for 7% to 8% of body weight, and weight to a certain extent, was proportional. Due to the significantly different total blood volume of donors with different body weight (W), body mass index (BMI) and height / weight (body size), this results in different amounts of blood donated by blood donors. It has been reported that the total blood volume and the occurrence of blood reaction has a very high correlation 〔1〕, the heavier the more the incidence of blood reaction
