The Complete 42-Biomarker TRT Safety Panel

Thinking about starting Testosterone Replacement Therapy (TRT), or already on your journey and need to track your progress? TRT can be life-changing, but it is not just about bumping up your testosterone numbers—it is about keeping the rest of your body running like a finely tuned machine.

The TRT Profile Advanced Blood Test is our gold-standard safety panel. It tracks 42 critical biomarkers to provide an in-depth look at your hormones, cholesterol, liver and kidney efficiency, red blood cell production, and prostate health.

Why Choose the Advanced TRT Panel?

Comprehensive Monitoring: Tracks how exogenous testosterone affects vital internal processes, including blood thickness (haematocrit) and cardiovascular health.

Professional Clinic Sampling: We provide the kit and arrange a visit to a partner clinic. A qualified phlebotomist will perform a standard venous blood draw from your arm, ensuring a high-volume, premium-quality sample.

Fast, Digital Results: Get your results emailed to you in an estimated 2 working days.

Expert Oversight: Includes a bespoke doctor's report evaluating your data.

Next-Steps Support: If your results indicate low testosterone, we partner directly with the specialists at Leger Clinic to help you navigate your treatment options or schedule a second baseline test.

What We Test: The 42 Biomarkers

Note: Testosterone supplementation can significantly alter your red blood cell production, lipid profiles, and natural hormone levels. Regular monitoring ensures you reap the benefits of TRT while mitigating potential side effects.

🩸 Blood Health & Clotting

Red Blood Cells (Haemoglobin, Haematocrit, Red Cell Count, MCV, MCH, MCHC, RDW): Crucial for tracking oxygen delivery and monitoring for polycythaemia (thickened blood), a common side effect of TRT.
White Blood Cells (Total Count, Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils): Assesses immune system function and flags underlying inflammation or infection.
Clotting Status (Platelet Count, MPV): Evaluates your blood’s ability to clot and repair wounds effectively.

🧪 Organ Function & Metabolic Health

Kidney Health (Creatinine, eGFR): Measures how effectively your kidneys are filtering metabolic waste.
Liver Health (ALP, ALT, GGT): Identifies signs of liver strain, inflammation, or bile duct issues.
Proteins (Total Protein, Albumin, Globulin): Evaluates nutritional status and how hormones are transported through your bloodstream.
Diabetes (HbA1c): Provides your average blood sugar levels over the last two to three months.

❤️ Cardiovascular & Iron Status

Cholesterol Status (Total Cholesterol, LDL, Non-HDL, HDL, Total/HDL Ratio, Triglycerides): TRT can alter your lipid profile; tracking this protects your long-term cardiovascular health.
Iron Status (Ferritin): The most sensitive marker for checking iron deficiency or iron overload.

🔄 Hormones & Prostate Health

Thyroid Hormones (TSH, Free T3, Free Thyroxine/T4): Ensures your metabolic engine is functioning correctly.
Key Hormones (Total Testosterone, Calculated Free Testosterone, SHBG, Oestradiol, Prolactin): Gives a clear picture of active, usable testosterone, potential oestrogen spikes, and pituitary health.
Fertility Markers (FSH, LH): Monitored because exogenous testosterone suppresses these hormones, often leading to a temporary drop in sperm count.
Prostate Health (PSA - Total): Screens for prostate protein levels. While TRT is not proven to cause prostate cancer, caution and consistent tracking are highly recommended.

📋 Essential Pre-Test Instructions

To ensure your results are highly accurate, please follow these preparation protocols closely:

Timing & Hydration

Schedule Early: Your blood sample must be collected between 6:00 am and 10:00 am. For accurate prolactin readings, ensure you have been awake for at least one full hour before your appointment.
Hydrate Well: Drink plenty of water before your test.
No Fasting Required: You do not need to fast, but you must avoid fatty foods for 8 hours prior to the draw.
Be Healthy: Wait until any short-term illness symptoms have completely settled before taking the test.

Activity Restrictions (48 Hours Before Test)

To prevent temporary, artificial spikes in your PSA and Prolactin levels, avoid the following for 48 hours before your appointment:

Vigorous exercise or heavy lifting.
Ejaculation or nipple stimulation.
Direct prostate stimulation (e.g., medical rectal examinations or receptive anal sex).
Note: If you have recently had a urinary tract infection (UTI), prostatitis, or a urological procedure (like a prostate biopsy or cystoscopy), wait at least 6 weeks before taking this test.

Medications & Supplements

Biotin: Stop taking biotin supplements 2 days before the test (if prescribed, discuss this with your doctor first).

Vitamins & Minerals: Take your sample at least 24 hours after your last supplement dose.

Thyroid Medications: If you take standard thyroxine, you can take it as usual. If you take desiccated thyroid extract (DTE) or liothyronine, wait until after your blood draw to take your dose.

TRT & Prostate Meds: Please declare if you are currently using TRT, finasteride, dutasteride, saw palmetto, amiodarone, or lithium in your supporting information.

TRT Eligibility & Health Safety

While TRT can restore energy, libido, mood, and muscle mass, it is not right for everyone.

According to guidelines from the British Society for Sexual Medicine (BSSM), treatment should be paused or avoided if you have certain stages of prostate cancer, breast cancer, severe chronic heart failure, an active desire to conceive, or preexisting high haematocrit levels. If your initial results indicate low testosterone, guidelines recommend scheduling a second, more in-depth confirmatory test four weeks later before initiating a treatment plan.

Biomarkers Tested

Total Biomarkers: 42

Red Blood Cells
Haemoglobin: The iron-rich protein in red blood cells that carries oxygen to the body's tissues; low levels indicate anaemia.
Haematocrit: Measures the percentage of red blood cells in the total blood volume.
Red Cell Count: The total number of red blood cells circulating in the blood, essential for delivering oxygen.
MCV: Mean Corpuscular Volume measures the average size of your red blood cells.
MCH: Mean Corpuscular Haemoglobin calculates the average amount of haemoglobin inside a single red blood cell.
MCHC: Mean Corpuscular Haemoglobin Concentration measures the density of haemoglobin within red blood cells.
RDW: Red Cell Distribution Width measures the variation in the size and volume of your red blood cells.

White Blood Cells
White Cell Count: The total count of white blood cells, used to detect infection, inflammation, or immune disorders.
Neutrophils: The most abundant white blood cell, acting as the first responder to bacterial infections.
Lymphocytes: White blood cells that produce antibodies and fight viral infections.
Monocytes: Large white blood cells that help clear dead tissue and defend against bacteria.
Eosinophils: White blood cells involved in fighting parasitic infections and allergic responses.
Basophils: The rarest white blood cells, which release histamine during allergic reactions.

Clotting Status
Platelet Count: Measures the number of platelets, the cells responsible for blood clotting and wound repair.
MPV: Mean Platelet Volume measures the average size of your platelets, indicating how actively the body is producing them.

Kidney Health
Creatinine: A waste product from muscle breakdown, filtered by the kidneys; high levels suggest reduced kidney function.
eGFR: Estimated Glomerular Filtration Rate is a calculation based on creatinine, age, and sex to assess kidney efficiency.

Liver Health
ALP: Alkaline Phosphatase is an enzyme found in the liver and bones; elevated levels can indicate bile duct obstruction or bone issues.
ALT: Alanine Aminotransferase is a liver enzyme; high levels are a specific indicator of liver inflammation or damage.
GGT: Gamma-Glutamyl Transferase is a liver enzyme often elevated by alcohol consumption, bile duct issues, or liver damage.

Proteins
Total Protein: Measures the sum of albumin and globulin in the blood to assess nutritional status and organ function.
Albumin: The primary protein produced by the liver, essential for maintaining blood volume and transporting hormones.
Globulin: A group of proteins including antibodies and enzymes that support the immune system.
SHBG: Sex Hormone Binding Globulin binds to testosterone and oestradiol, regulating their bioavailability in the body.

Diabetes
HbA1c: Glycated haemoglobin, which provides an average of blood sugar levels over the previous 2 to 3 months.

Cholesterol Status
Total Cholesterol: The total amount of cholesterol in the blood, including LDL, HDL, and other lipids.
LDL Cholesterol: Low-Density Lipoprotein, or "bad" cholesterol, which can deposit plaque in artery walls.
Non HDL Cholesterol: A calculation (Total minus HDL) representing all cholesterol types that can cause arterial blockages.
HDL Cholesterol: High-Density Lipoprotein, or "good" cholesterol, which removes excess cholesterol from the bloodstream.
Total Cholesterol : HDL: A ratio used to predict heart disease risk; a lower number is generally better.
Triglycerides: A type of fat (lipid) in the blood used for energy; high levels increase the risk of heart disease.

Iron Status
Ferritin: The primary protein that stores iron in the body; it is the most sensitive marker for iron deficiency or overload.

Thyroid Hormones
TSH: Thyroid Stimulating Hormone, produced by the pituitary gland to control the thyroid's hormone production.
Free T3: Triiodothyronine, the active thyroid hormone responsible for regulating metabolism.
Free Thyroxine: Also known as Free T4, the main hormone released by the thyroid, which is converted into active T3.

Hormones
FSH: Follicle Stimulating Hormone stimulates the production of sperm in men and egg maturation in women.
LH: Luteinising Hormone triggers the release of testosterone in men and ovulation in women.
Oestradiol: The primary form of oestrogen, critical for bone health, reproductive function, and hormonal balance in both sexes.
Testosterone: The primary male sex hormone, essential for muscle mass, bone density, libido, and mood.
Free Testosterone - Calc.: An estimate of the unbound testosterone available for the body to use, calculated from total testosterone, SHBG, and albumin.
Prolactin: A hormone produced by the pituitary gland; high levels can suppress testosterone production and affect sexual function.

Prostate
PSA - Total: Prostate Specific Antigen is a protein produced by the prostate; levels are monitored to screen for prostate enlargement or cancer.

How to prepare for your test

Prepare for your test by following these instructions.

Sample collection and timing
Take your sample between 6am and 10am.
Take this test when any symptoms of short-term illness have settled.
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).
Avoid nipple stimulation or heavy meals before taking the test, as these can increase prolactin levels.

Fasting and hydration
Avoid fatty foods for eight hours before your test, you do not need to fast.
Stay well hydrated before your test.

Medications and supplements
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.
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.

Frequently Asked Questions

Frequently asked question about our blood testing and diagnostic services. If there is a question not answered feel free to contact us!

Are there any age restrictions for your tests?

Yes, our services are currently available only to individuals aged 18 and over. We require you to confirm your Date of Birth in your Customer Account area.

Can I book a professional to take my blood?

Yes! We offer options for a clinic visit or a nurse home visit for a professional venous draw. You can select this option when choosing which test is right for you!

If you prefer to book your own phlebotomist, no problem! Simply select this option prrior to processing your order and we will send the kit to your home for you to arrange your own clinic visit.

Can I share my results with my own GP?

Yes, and we encourage it! You can download your doctor-reviewed report as a PDF from your secure portal to share with your GP or specialist during your next appointment.

Can I take these tests if I am pregnant or breastfeeding?

While you can take the tests, pregnancy and breastfeeding significantly alter your hormone and nutrient levels. This means our standard "normal" ranges may not apply to you. We recommend consulting your midwife or GP before ordering.

Can I use these tests to monitor an existing medical condition?

Our tests are excellent for tracking trends and monitoring wellness. However, they should not be used to self-diagnose or adjust prescribed medication without first consulting your treating physician and GP.

Do I need a doctor’s referral or a prescription?

No. Optimal You provides a private service that allows you to take control of your health data without needing to visit a GP first.

How do I get started with a blood test?

Simply choose your test on our website and checkout.

Whilst on the particular test you are looking to purchase, select a test type from the drop down. You have three or four options depending on the type of test you are purchasing:

At Home Finger Prick Blood Test - You will receive you sample kit via the post. Simply follow the instructions enclosed and return using the packaging provided.

Book a Venous Draw at a Clinic - You will receive an email after you have processed your order containing instructions on how to book your clinic appointment. Our partners have national coverage of the UK to make your sample collection convenient to you whilst maintaining our quick service times. You can find your closest clinic via our partner medichecks on our clinic finder page.

Book a Venous Draw at Home with a Nurse - Once you have chosen this option, simply go through our checkout process, a nurse will be in touch to book your at home visit to complete your sample.

Self arrange a Profesional Sample Collection - You will receive your sample collection kit in the post for you to take to your chosen phlebotomy clinic. Note you will be responsible for arranging your appointment and for any associated fees.

How long does it take to get my results?

Most results are ready within 2–5 working days after the lab receives your sample. You will receive an email notification as soon as they are ready.

How soon do I need to post my sample back?

To ensure the stability of your biomarkers, you should post your sample on thesame dayyou collect it. Avoid collecting samples on a Friday afternoon or over the weekend to prevent them from sitting in the post; Monday through Thursday is best.

Is my data secure?

Absolutely. We use industry-standard encryption, and your data is stored securely in compliance with GDPR. Only you and our medical team have access to your results.

Is there a specific day or time I should take my sample?

Most tests are best performed first thing in a morning, especially if fasting is required. For hormonal tests (like Testosterone or Menopause profiles), we usually recommend collecting your sample before 10:00 AM when hormone levels are most stable.

You will receive additional guidance post purchase to give you all of the information needed as some tests have different guidelines.

What happens if I struggle to get enough blood from a finger-prick?

Don't worry, it happens! We include extra lancets in every kit. Pro tip: Make sure your hands are very warm (try soaking them in warm water) and stay well-hydrated for 24 hours before your test. If you still can't collect enough, contact us and we can help you arrange a venous blood draw instead.

What happens if my results are abnormal?

If a result is critically outside the normal range, our medical team will highlight this and provide clear guidance on the next steps during our contact with you, which may include you seeing your GP, going to A&E or calling the NHS on '111'.

What is the difference between a Finger-Prick and a Venous Draw?

A finger-prick is a self-collection kit done at home. A venous draw is a traditional blood sample taken from a vein by a professional. Some advanced tests (like our TRT or Enhanced Profiles) require a larger sample and are best done via a venous draw.

Who reviews my results?

Every report is reviewed by a qualified UK doctor. They provide personalized comments to help you understand what your biomarkers mean for your health.

Why are my results different from a previous test I had?

Biomarkers can fluctuate based on the time of day, your diet, stress levels, recent exercise, or even the lab equipment used. This is why we focus on "ranges." If you see a significant change, our medical team’s comments will help put that data into context.
