Abstract

BACKGROUND: The aim of this study was to improve the sensitivity of the congenital adrenal hyperplasia (CAH) neonatal screening by including second-tier steroid profiling on a DBS using LC-MS. RESULTS: We developed a method to measure the steroid profile in DBS and established gestational age-specific reference ranges of cortisol, cortisone, 11-deoxycortisol, 21-deoxycortisol, 17-hydroxyprogesterone, testosterone, Δ4-androstenedione, corticosterone and 11-deoxycorticosterone using 450 heel prick samples of neonates, participating in the Dutch Screening Program. Analyzing 92 cards with a positive CAH screening showed that only 21-deoxycortisol was 100% specific for diagnosed CAH patients. CONCLUSION: Steroid precursors can be measured in DBS and we suggest to implement the method as a second tier testing for CAH in The Netherlands.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
