If need be to specify a sample taken in the morning or in the evening, please select the specific analysis codes:
Sampling done between 7 a.m. and 10 a.m. : ACTHM
Sampling done in the evening: ACTHS
If sampling on EDTA tube: on cooled tube, refrigerated centrifugation, immediate decantation and freezing
Not to to be performed on haemolysed sample1 individual aliquot for this analysis.
CIRCADIAN RHYTHM: This biological molecule has a circadian rhythm (maximum concentration in morning), with a sufficiently significant amplitude to have an important influence on the clinical interpretation
ATTENTION: interference possible in patients treated with biotin (vitamin B7, B8 or H) or taking any food supplement containing biotin. Essential to STOP treatment 8 days before taking the sample.

<=30 days: Reference values at 8 hours - neonatal period: < 100 ng/L
Reference values for ACTH:
morning: 5 - 60 ng/L | 1.1 - 13.2 pmol/L
