Overview
According to Endocrine Society Clinical Practice Guideline, screening for 21-hydroxylase deficiency by measuring 17-hydroxyprogesterone is recommended for all newborns. The Endocrine Society's Clinical Practice Guideline recommends that genetic counseling be provided for individuals who are planning to conceive, and there is a family history of 21-hydroxylase deficiency.
Screening
According to Endocrine Society Clinical Practice Guideline, screening for 21-hydroxylase deficiency by measuring 17a-hydroxyprogesterone is recommended for all newborns.
- Blood sample on filter paper should be obtained from heel puncture preferably between two and four days after birth.
- Screening programs should be done using a two-tier protocol (initial immunoassay with further evaluation of positive tests by liquid chromatography/tandem mass spectrometry.
- Most affected neonates have concentrations greater than 3500 ng/dL (105 nmol/L).[1][2]
Genetic counseling
The Endocrine Society's Clinical Practice Guideline recommends that genetic counseling be provided for individuals who are planning to conceive, and there is a family history of 21-hydroxylase deficiency.[2]
