Abstract

The zinc content in whole blood and serum was determined in 239 healthy males and 217 healthy females by atomic absorption spectrophotometry.The mean level of zinc obtained in whole human blood from males was 607.0 +/- 105.3 micrograms/100 ml and in females 585.2 +/- 122.9 micrograms/100 ml.The mean level of zinc in serum was 116.6 +/- 55.2 micrograms/100 ml and 105.2 +/- 66.9 micrograms/100 ml in males and females respectively.The zinc concentration in whole blood and serum in males proved to be slightly higher than in females though the difference is not statistically significant.For the males a positive correlation was found between age and the zinc level in whole blood and serum; this is only statistically significant in whole blood.In females, the zinc level in whole blood showed a positive correlation with age which was not statistically significant, while in serum this correlation was negative and statistically significant.
