Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The aim of this study is to determine the volume of the thyroid gland in preterm infants born between 24 and 32 weeks of gestation inborn or admitted to the unit within 14 days from birth and compare it with the results of TSH and FT4 blood concentration. Besides, the objective of the study is to determine values of thyroid hormones in premature infants born before 33 wk gestation to help neonatologist to interpreter the thyroid hormone results

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The aim of this study is to determine the volume of the thyroid gland in preterm infants born between 24 and 32 weeks of gestation inborn or admitted to the unit within 14 days from birth and compare it with the results of TSH and FT4 blood concentration. We will performed the thyroid ultrasound to estimate the thyroid volume to aid in the comparative evaluation of infants with suspected thyroid disease. The value of sonography thyroid volume will give specialists possibility to identify a gland as normal, small or enlarged. Besides, the objective of the study is to determine value of thyroid hormones in premature infants born before 33 wk gestation to help neonatologist to interpreter the thyroid hormone results
