A systematic review of hair cortisol during pregnancy: Reference ranges and methodological considerations.

ABSTRACT: The present study systematically reviewed 56 articles that assessed hair cortisol concentrations during pregnancy collected from PubMed, Scopus, and Web of Science on 8/9/19 and updated on 6/29/20. Our goals were to establish reference ranges by trimester based on published studies. The majority of any given sample (e.g., 70 %, the range of -1SD to +1SD) is expected to fall between 0 and 34.15 pg/mg in trimester 1 and 2, and between 8.59 and 44 pg/mg in trimester 3, with very wide ranges (e.g., values of >250 pg/mg) and substantially higher values (e.g., averages of 200's-300's reaching as high as 768 pg/mg) coming out of one specific lab. Delineating a reference range for hair cortisol concentrations across pregnancy is challenging because of known factors like differences in values retur
