Cortisol Blood Test

Attend your appointment and one of our experienced nurses or phlebotomists will collect your blood sample. If your test also includes another sample, such as urine or stool, we will provide the necessary collection kit and clear instructions.

Results are typically available within Same day. Some individual markers may take longer if they require specialist laboratory processing. We will normally wait until the full profile is complete before issuing your reviewed results.

Fasting is not usually required, but timing is important because cortisol changes naturally throughout the day. Unless your clinician has requested a different time, a morning sample—typically between 8:00 am and 10:00 am—is usually preferred.
