BLOOD TESTING // AUSTRALIA & UK
Blood biomarkers
Biomarkers are measurements from your blood. They can add useful information to a review of your eating, training and health, but no single result explains how you feel.

What can the results tell us?
Explore examples of the markers we may review. Results need context and cannot diagnose fatigue, under-fuelling or RED-S on their own.
17 markers
Blood markers explained
Testosterone (Total & Free)
Hormones & RED-S
Helps assess hormone levels. Age, medication, sample timing and recent training can affect the result.
Oestradiol
Hormones & RED-S
A hormone involved in menstrual and bone health. Cycle timing matters; a low result needs clinical context.
SHBG
Hormones & RED-S
A protein that binds sex hormones. It helps put other hormone results into context.
FSH & LH
Hormones & RED-S
Hormones involved in reproductive function. Results vary with cycle timing and need medical context.
PSA
Hormones & RED-S
A prostate-related marker used only when appropriate. Testing and interpretation should be discussed with a doctor.
TSH (Thyroid)
Thyroid & Energy
A hormone that helps regulate the thyroid. An abnormal result needs a doctor’s assessment.
Free T3 & Free T4
Thyroid & Energy
Thyroid hormones that help regulate energy use. These tests do not measure your metabolic rate.
Ferritin & Serum Iron
Oxygen & Iron
Helps assess iron stores and circulating iron. Inflammation and other factors can affect the results.
Full Blood Count (FBC)
Oxygen & Iron
Measures blood cells, including haemoglobin, which carries oxygen. Abnormal results need clinical review.
Creatinine
Liver & Kidney
Used to assess kidney function. Muscle mass, hydration and recent exercise can affect the result.
ALT & ALP (Liver)
Liver & Kidney
Enzymes used in liver and wider health checks. Raised levels have several possible causes.
Albumin & Globulin
Liver & Kidney
Blood proteins that provide information about wider health. They do not measure nutrition status on their own.
Bilirubin
Liver & Kidney
A substance produced when red blood cells break down. Raised levels need clinical context.
GGT
Liver & Kidney
An enzyme used in liver checks. Medication, alcohol and other factors can affect levels.
C-Reactive Protein
Inflammation
A non-specific inflammation marker. It does not identify the cause of inflammation.
Total Cholesterol & Triglycerides
Lipids
Blood fats used in cardiovascular health assessment. Interpretation belongs with your clinician.
HDL & LDL
Lipids
Cholesterol measurements used alongside other factors to assess cardiovascular risk.

Gareth reviews results to guide fuelling and training, not to diagnose or treat illness. Blood tests do not diagnose RED-S on their own. Clinical concerns are referred to your GP or sports doctor.
