Best practice for this test
Prepare for a result that can be interpreted properly.
A rested morning fasted sample gives the most consistent glucose and iron assessment.
Avoid strenuous training for 24 to 48 hours before collection and arrive normally hydrated.
Record recent training load, illness, supplements and, where relevant, menstrual history.
No specific cycle day is required because reproductive hormones are not included in this fixed profile.
Your safety comes first. Any later collection instructions sent by Beaches or Inuvi take priority. Do not stop prescribed medication or fast if it could be unsafe. Contact us first if you have diabetes, are pregnant, are prone to fainting or are unsure about medication.

About this profile
What it is designed to explore.
Relative Energy Deficiency in Sport cannot be diagnosed or excluded by a blood test alone. This profile is designed to contribute objective information to a wider assessment that considers energy availability, symptoms, menstrual or endocrine health, bone health, training and recovery.

A responsible service
Testing supports care. It does not replace it.
If you feel acutely unwell or have symptoms that need urgent assessment, seek appropriate medical care rather than waiting for a private blood test.
A result outside the reference range does not always mean illness, and a result inside it does not rule every problem out. Interpretation depends on symptoms, history and context.
