Blood selenium levels of Indians: Delhi area
- 10 Downloads
Whole blood and plasma selenium levels were measured in 40 healthy Indian residents living in and around Delhi (20 males and 20 females). The mean whole blood and plasma selenium levels were 169.0±40 and 139.0±36.7 ng/ml in males and 161.2±46.2 and 128±40.6 ng/ml (mean±SD) in females, respectively. These blood levels did not differ significantly between males and females and are consistent with adequate selenium status. From regression plots based on the present results and literature data, it is expected that the probable mean selenium intake could be about 122 and 112 μg/day in males and females respectively.
