Looking beyond hormones in TRT monitoring
Our most complete TRT profile combines hormone markers with blood health, liver function, kidney function, cholesterol, thyroid function, ferritin, blood sugar, protein, and prostate markers that are commonly monitored during testosterone replacement therapy.
By bringing these markers together into a single profile, it provides the widest overview in our TRT range and can be used as a baseline before treatment or to monitor changes over time.
You might consider this test if you’re preparing to start testosterone replacement therapy, are receiving ongoing TRT, have been advised to monitor a wider range of health markers, or would like our most complete TRT assessment.

- Prepare for your test by following these instructions.
- Take your sample between 6am and 10am.
- Avoid vigorous exercise, ejaculation, or direct prostate stimulation (e.g. a rectal examination or receptive anal sex) for 48 hours beforehand – all of these can raise your PSA level.
- Wait at least six weeks before taking this test if you\’ve had a urine infection, prostatitis (prostate infection), or urological intervention (e.g. prostate biopsy or cystoscopy).
- Please let us know in the supporting information if you take testosterone replacement therapy (TRT), finasteride, dutasteride, or saw palmetto, as these can also affect your results.
- Avoid nipple stimulation, as this can increase prolactin levels.
- Taking this test fasted is preferable but not compulsory as eating can impact prolactin levels.
- Take this test when any symptoms of short-term illness have settled.
- Stay well hydrated before your test.
- Take your sample at least 24 hours after any vitamin or mineral supplements.
- Do not take biotin supplements for two days before this test, discuss this with your doctor if it is prescribed.
- If you take levothyroxine or desiccated thyroid extract (DTE), take your blood test before your dose for the most accurate thyroid function results.
- If you have to take your blood test later in the day, aim to leave at least six hours between taking levothyroxine medication and your blood draw (or 12 hours after DTE/T3 medication).
- Please also let us know in the supporting information if you take amiodarone or lithium, as these can also affect your results.
