STUDY OF THYROXINE (T4) AND THYROID STIMULATING HORMONE (TSH) LEVELS IN NEWBORNS TO FIND A CORRELATION BETWEEN T4 AND TSH LEVELS WITH GESTATIONAL AGE AND TO COMPARE T4 AND TSH LEVELS IN HEALTHY AND SICK NEWBORN BABIES
Congenital hypothyroidism is the most common cause of preventable mental retardation. The present study was conducted on newborns over a period of one year, with an aim to compare T4 and TSH levels in healthy and sick babies and to find a correlation between T4 and TSH levels with gestational age. Enzyme Linked Immunosorbent Assay (ELISA) technique was used for assessing T4 and TSH levels. The study showed a significant positive correlation of serum T4 with gestational age and significant negative correlation of serum TSH with gestational age. In comparison of healthy and sick neonates with T4 and TSH levels, the differences observed were not significant
