Abstract
This study is to determine the level of IG E in cord serum and correlate with birthweight and gestational age. Cord serum was collected from 66 preterm newborns varying from 26 weeks to 36 weeks AGA, Mean gestational age 32.5 – 2.78 weeks mean weight 1868 gms ± 542 gms. Sera were separated stored at -20°C until estimation was done. Immunoglobulin E was measured by quantitope 125l – IG E radioimmunoassay and all values are expressed in IU/Ml. The samples were analyzed in duplicate. The interassay variation was less than 10% and intraassay was less than 5%. As the IG E distribution in cord serum was assymetric the logarithmic value was used for simple linear regression analysis. Immunoglobulin E mean concentration 0.795 IU/Ml median 0.125 and the range 0 to 10.0 IU/Ml SD ± 1.81. Correlation coefficients for the log of IG E concentration vs gestational age (r = .003) and vs birthweight (r = 0.119) were not significant.
