Overview

Cortisol 4pm testing captures your stress hormone level during its normal afternoon decline. Healthy adrenal function shows high morning cortisol gradually dropping through the day, reaching this mid-afternoon checkpoint significantly lower than morning peak.

This test helps assess whether your daily rhythm is functioning—afternoon crashes may reflect abnormally low cortisol, while evening anxiety or sleep difficulty may indicate cortisol that's not declining appropriately, available across Australia.

Most informative when compared to morning cortisol values to see the full pattern.

Symptoms

Essential for people with afternoon energy crashes, evening anxiety, sleep onset difficulty, or comprehensive adrenal rhythm assessment.

Questions

  • 4pm captures cortisol during its normal afternoon decline. Comparing afternoon to morning levels reveals whether your rhythm is functioning properly.
  • Afternoon cortisol should be significantly lower than morning levels—typically 50-70% lower. The decline matters more than absolute values.
  • Persistently elevated afternoon cortisol suggests chronic stress, Cushing's syndrome, or rhythm disruption. You may feel wired or anxious in evenings.
  • Very low afternoon cortisol with low morning levels suggests adrenal insufficiency. Low afternoon with normal morning may be normal variation.
  • Yes, comparing morning and afternoon levels provides more information than either alone. Some providers order both simultaneously.
  • High evening cortisol can interfere with sleep onset. The natural decline should reach lowest levels at bedtime.

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.

"I'm a little biased as I work here! However, I love that The Bloody Good Test tracks my health over time. 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"
