Sleep Profile Extensive Saliva Test

$110.00 AUD

Struggling with sleep and wondering if your hormones could be a factor in why you can't switch off at night or feel exhausted in the morning?

This saliva test measures both melatonin and cortisol — the two hormones most responsible for your sleep-wake cycle — at multiple points across the day and evening. It provides insights into the hormonal factors that may be contributing to poor sleep, whether that's difficulty falling asleep, staying asleep, or waking unrefreshed.

By tracking extended readings of both hormones, this test gives your practitioner a detailed view of how your body transitions between wakefulness and sleep. It's particularly valuable for shift workers, people with chronic insomnia, or anyone whose sleep hasn't responded to standard approaches.

Overview

Sleep is regulated by a delicate interplay between two key hormones: melatonin and cortisol. Melatonin, produced by your pineal gland, signals your body that it's time to sleep. Cortisol, your primary stress hormone, should naturally decline in the evening to allow melatonin to take over. When this balance is disrupted, sleep quality can be affected.

The Sleep Profile Extensive test takes multiple readings of both melatonin and cortisol across your day and evening, providing your practitioner with a detailed hormonal timeline. Unlike a standard sleep profile, the extensive version captures extra data points — giving a more complete picture of how these hormones rise and fall over a longer duration.

This additional detail is particularly important for shift workers whose hormonal rhythms may be significantly disrupted, and for anyone with complex or treatment-resistant sleep issues. Pinpointing the exact time window where melatonin or cortisol deviates from normal helps your practitioner choose the right intervention for that specific disruption.

Symptoms

This test is designed for anyone experiencing persistent sleep difficulties — including trouble falling asleep, frequent waking, early morning waking, or feeling unrefreshed despite adequate sleep. It's especially useful for shift workers, people with chronic insomnia, those experiencing anxiety-related sleep issues, and individuals whose sleep problems haven't improved with standard interventions. Healthcare practitioners use this test to pinpoint hormonal imbalances and tailor treatment plans.

Questions

  • The Extensive version includes additional melatonin and cortisol readings, giving your practitioner more data points to track hormonal activity over a longer period. This extra detail is particularly useful for complex cases or shift workers.
  • You'll receive a kit with collection tubes. At each scheduled time, you collect a small saliva sample using the device provided. It's simple, painless, and done in the comfort of your own home.
  • This test identifies hormonal imbalances in melatonin and cortisol that commonly contribute to sleep problems. It doesn't diagnose conditions like sleep apnoea, which requires different testing. However, it addresses one of the most common — and treatable — causes of poor sleep.
  • Absolutely. In fact, this test is particularly valuable for shift workers. Collect your samples according to your usual sleep-wake schedule and note your shift pattern on the form. Your practitioner will interpret the results in the context of your work routine.
  • Results are typically available within 3-5 business days after the laboratory receives your samples.
  • Yes. Melatonin supplements, sleep medications, and corticosteroids can influence your results. Discuss any supplements or medications with your practitioner before testing, but never stop prescribed medication without medical advice.

How to prepare

Collect three saliva samples at the times specified in your test kit instructions. Avoid eating, drinking (other than water), brushing teeth, or using mouthwash for at least 30 minutes before each collection. Avoid alcohol on the day of collection. Try to follow your normal routine on collection day so results reflect your typical patterns. If you're a shift worker, collect according to your usual sleep-wake schedule and note your work pattern on the form provided.

After the test

Discuss your results with a healthcare practitioner experienced in sleep and hormonal health. Depending on your specific imbalances, they may recommend melatonin support, cortisol-lowering strategies such as evening relaxation practices, targeted supplementation, or sleep hygiene adjustments. For shift workers, specific chronotherapy approaches may be suggested. Retesting after implementing changes helps confirm improvements in your hormonal rhythm.

Your test results will be available in your private dashboard. If there are any urgent issues, we'll let you know so you can follow up with your health professional.

Understanding results

Your results will show melatonin and cortisol levels plotted across the collection times, compared to healthy reference ranges. In a well-functioning system, cortisol should be highest in the morning and decline throughout the day, while melatonin should rise in the evening as cortisol falls. Elevated evening cortisol can prevent sleep onset, while low melatonin production can make it difficult to fall or stay asleep. Your practitioner will interpret the specific patterns in your results and identify where the hormonal rhythm is breaking down.

Simple health checks in my control

I didn't know that private blood tests were an option. Tried this platform as the packages suited what I wanted for a good price. Easy to follow instructions, and super quick results. Platform provides more information than my gp's ever have on the tests and what the results meant. Would like more clinics to be able to test at (specifically Capital Pathology) but there is a decent network. Will continue to use.

After turning 40, I wanted to make sure I wasn't going to drop dead from something basic I should have known about earlier. Measuring all my core biomarkers each year gives me peace of mind my health is on the right track"
