Cordblood zine, adenosine deaminase, total proteins, albumins, albumin/globulinratio andhemoglobin levelswereestimated in lowbirthweight(LBW)andnormalbirthweightneonates. Thirtyfulltermnewbornswho were weighinglessthanor equal to2.5kgandthirtyfulltermnewborns whowere weighingmorethan2.5kgservedas testandcontrol groups respectively. Cord bloodsamples were collectedfrom these subjects immediately afterdelivery and serum was used for the analysisofzinc, adenosinedeaminase, totalproteins, albumins, albumin/ globulinratio usingstandard methods. Haemoglobinwas estimated in thewholeblood. Theresultsofthestudyindicatedthatthezinclevelsin thecordbloodoflowbirthweightand normal birthweightwerenotsignifi cantlydifferent.
