Radiolabel Validation of Cortisol in the Hair of Rhesus Monkeys

Hair is becoming an increasingly popular matrix to measure cortisol as a biomarker of stress. It has been used in a diverse range of topics including: autism (Ogawa et al., 2017), the impact of asthma in children (Kamps et al., 2014), socioeconomic status (Vliegenthart et al., 2016), sleep (Maurer et al., 2016) as well as the association of hair cortisol with disease (e.g. Pereg et al., 2013). It has also been used to assess steroid hormones in utero from neonates, a measure that is only possible in hair, and more recently nails (Tegethoff et al., 2011), without invasive sampling.
