Patient's question:
My baby was born at 34 weeks plus 6 days, and it has been 28 days now. The blood screening test revealed a 17α-hydroxyprogesterone level of 17.3 nmol/L. What is the normal range for this value? What symptoms might reappear?Doctor's answer:
This is a screening test for congenital adrenal hyperplasia. It is caused by a deficiency in a hereditary metabolic enzyme. The normal reference range for males is 0.70–3.6 ng/ml. If your baby's 17a-hydroxyprogesterone level is higher than the reference value, it may indicate congenital adrenal hyperplasia. This condition primarily interferes with growth and development and causes electrolyte imbalances. Regular follow-up tests should be conducted, and if it is indeed this condition, active diagnosis and treatment should be initiated.
