Why use this test? Checking the precise dynamics of morning cortisol secretion is important if you suspect that the cortisol awakening response is not occurring properly. This can also be useful in context of the daily cortisol pattern.
More: CAR is the rise in cortisol levels observed at 30 minutes post-awakening (approximately 35-60% above the waking value) followed by an expected decline one hour after waking. The behaviour of cortisol is an important physiological response to anticipation of the day ahead and is a key indicator of central stress response system health. The waking, 30 minute, and 60 minute cortisol results comprise something of a “mini stress test.”

The laboratory will not compromise themselves by testing saliva that is past its used by (too viscous). Their only concern is the accuracy of the results and the integrity of the laboratory. So when a sample turns up that has been delayed by Australia Post, and it isn't fit for testing, they have no hesitation in rejecting it, and we start the process over (at no cost to you).
More: The official position of saliva travel time is that saliva samples are good for (up to) 12 days, Despite the guidelines, each sample is assessed for suitability upon arrival prior to testing.
