morning cortisol blood test (if I recall right) is just crawl out of bed, don't drink, eat or even clean your teeth (probably wera your clothes to bed to save any effort), then get someone to drive you to blood test first thing on waking if possible (our test places open about 7.30AM), and get blood test about 7.30AM-8AM. then go home have brekkie etc. best if also get an aft test about 4PM to compare the two.
Doing anything supposedly causes the blood cortisol to rise and you want to test if it is low on waking. if you could just test it in bed, even better! LOL That's from memory. It's tot tst if your sortisol rises naturally overnight as it should to OK levels or if not.
Afternoon does not have to be fasting. Gee my recall is poor, I think about 4PMish?
Hope this helps as to why they say that about the fasting.Sorry I clean forget what the salty taste means... had it and now forget.. back in 2002-2203 ish
