Biological samples ⏵ Saliva assays

Description

This category contains information on the assays that have been performed on the 1946 birth cohort saliva samples and their results.Survey members attending the clinic were asked to provide a saliva sample at the clinic and then three further samples (at 9.00-9.30pm the evening they attended clinic and then on waking the following morning and again at 30 minutes after waking). Survey members were asked to put their evening sample in the green coloured tube, their waking sample in the yellow coloured tube and their waking + 30 sample in the red coloured tube. Where they used the incorrect colour, the order of the cortisol readings was amended. The correct final sequence for the four cortisol samples is waking, waking + 30, clinic sample, evening sample. Note that the clinic and evening samples were collected the day before the waking and waking + 30 samples.
