Interpreting Your Potency Report: Guidance from Our Clinical Nursing Team
Confused by your potency report results? Our UK clinical nursing team explains key biomarkers, what your numbers may indicate, and your next steps after testing.
Receiving your potency report can feel both informative and, at times, a little overwhelming — especially if you are unsure what the numbers and reference ranges actually mean. At Health Screening Clinic, our nurse-led team is here to help you understand what your results may suggest, so that you feel confident and informed when discussing them with an appropriate healthcare professional.
This educational guide walks you through the key biomarkers typically featured in a potency or male hormone screening report, what the values may indicate, and how to think about your results in a broader wellbeing context.
What Is a Potency Report?
A potency report is a blood-based hormone screening result that evaluates key biomarkers associated with male reproductive health, sexual function, and hormonal balance. It typically includes measurements of testosterone (total and free), sex hormone-binding globulin (SHBG), luteinising hormone (LH), follicle-stimulating hormone (FSH), prolactin, and oestradiol.
In brief: A potency report provides a hormonal snapshot — usually covering 4–8 biomarkers — that may highlight patterns relevant to energy levels, libido, fertility, and overall male hormonal health. Results are reviewed in the context of age-related reference ranges and should always be discussed with a qualified healthcare professional.
Testing and reporting are the first step. Our clinic provides results clearly and professionally — the next steps in your care pathway are guided by those findings in consultation with an appropriate clinician.
Key Biomarkers in Your Potency Report — Explained
Understanding each marker individually helps you read your report with greater clarity. Below is a breakdown of the most commonly included biomarkers and what they may suggest when values fall outside the typical reference range.
Total Testosterone
Testosterone is the primary male sex hormone and plays a role in muscle mass, mood, energy, libido, and reproductive function. Total testosterone measures both bound and unbound testosterone in the bloodstream.
- Reference range (adult males, UK labs): Approximately 8–29 nmol/L
- What lower values may suggest: Reduced energy, mood changes, or reproductive concerns — though context is always important
- What higher values may suggest: Can sometimes occur in certain health conditions; requires clinical review
Free Testosterone
Free testosterone refers to the biologically active fraction not bound to proteins. It may be a more clinically meaningful indicator in some individuals, particularly where SHBG levels are elevated. Our guide on total testosterone vs free testosterone explains this distinction in more depth.
Sex Hormone-Binding Globulin (SHBG)
SHBG is a protein that binds to testosterone in the blood, effectively reducing the amount available for use by the body. Elevated SHBG can mean less free testosterone is available, even if total testosterone appears within range. See our guide on why the SHBG test matters for monitoring male health for further detail.
Luteinising Hormone (LH) and Follicle-Stimulating Hormone (FSH)
LH and FSH are produced by the pituitary gland and regulate the testes. Their levels can help indicate whether a hormonal imbalance may originate from the testes themselves or from the regulatory axis in the brain.
Prolactin
Prolactin is typically associated with breastfeeding but is present in all individuals. Elevated levels in males may sometimes be associated with reduced libido or fertility concerns and can occasionally point to other areas worth investigating further.
Oestradiol
A form of oestrogen also present in males, oestradiol helps maintain bone density and sexual function. Both significantly elevated and very low levels may be clinically relevant.
Practical Insight: No single biomarker tells the full story. Your report should always be considered as a complete hormonal picture, not a collection of isolated figures.
Understanding Your Reference Ranges
| Biomarker | Typical Adult Male Range (UK) | Possible Low Implication | Possible High Implication |
|---|---|---|---|
| Total Testosterone | 8–29 nmol/L | Fatigue, low libido, mood changes | Rare; requires clinical context |
| Free Testosterone | 0.2–0.6 nmol/L | Reduced available hormone | May relate to low SHBG |
| SHBG | 10–57 nmol/L | More free testosterone available | Less free testosterone available |
| LH | 2–9 IU/L | May point to pituitary signal issue | May indicate testicular concern |
| FSH | 2–12 IU/L | May affect sperm production signals | Can suggest testicular feedback |
| Prolactin | 86–324 mIU/L | Rarely clinically significant when low | May warrant further investigation |
| Oestradiol | 28–156 pmol/L | May affect bone and sexual health | Can sometimes relate to testosterone conversion |
Please note: Reference ranges may vary slightly between laboratories. Always interpret your results against the ranges printed on your specific report.
Who Should Consider a Potency Screening Test?
A potency or male hormone screen may be worth considering for a range of individuals, particularly those who have noticed changes in their health and wellbeing that they would like to explore further.
You may wish to consider testing if you:
- Have noticed a sustained reduction in energy or motivation
- Are experiencing changes in libido or sexual function
- Are exploring your fertility profile as part of family planning
- Have a family history of hormonal conditions
- Are approaching or beyond 40 years of age and wish to monitor hormonal changes
- Are already under the care of a clinician and need a baseline screen
Our male health screening options are designed to offer clarity and an informed starting point. Our guide on essential health checks men over 40 need covers the wider markers worth monitoring alongside your potency report.
Practical Insight: Screening is proactive, not reactive. Many individuals who request potency testing are in good overall health and simply want a clearer picture of where they stand hormonally.
How Often Should You Have a Potency Screen?
There is no universal rule, but general guidance suggests:
- First-time screening: At any age when symptoms or concerns are present
- Routine monitoring (40+): Annually or every two years, depending on previous results and personal circumstances
- Post-lifestyle change: After significant weight loss, change in physical activity, or a period of sustained stress
- During fertility planning: As part of a broader pre-conception health assessment
Our health screening packages include options suited to different stages of life and health monitoring goals.
What Your Results May Indicate — And What Comes Next
Receiving results outside the reference range does not automatically signal a serious problem. Hormonal levels fluctuate and are influenced by factors including sleep quality, stress, recent illness, time of sample collection, and body weight.
If your results are within the reference range: This is broadly reassuring. However, normal values do not guarantee the absence of any concern — if you have ongoing symptoms, seek appropriate healthcare advice.
If your results are outside the reference range: This may suggest that further investigation is worthwhile. Our clinical team will highlight any values of note in your report. We recommend discussing these findings with your GP or an appropriate healthcare professional, who can provide clinical interpretation in the context of your full medical history.
If results are significantly outside range: If you are experiencing severe or acute symptoms alongside abnormal results, please seek urgent medical care promptly.

Frequently Asked Questions
1. What is a potency report and what does it measure?
A potency report is a hormone blood test result covering key male reproductive and sexual health markers, including testosterone (total and free), SHBG, LH, FSH, prolactin, and oestradiol. Together, these biomarkers may indicate patterns relating to libido, energy, fertility, and hormonal balance. Results should always be reviewed with a healthcare professional.
2. What does it mean if my testosterone is low on my potency report?
A lower testosterone reading may sometimes be associated with reduced energy, changes in mood, or libido concerns. However, a single result should always be considered alongside symptoms and other markers. Low readings do not always confirm a clinical condition and should be discussed with an appropriate clinician.
3. Can my potency report results change over time?
Yes. Hormonal levels naturally fluctuate due to factors such as age, stress, sleep, and lifestyle. It is not uncommon for a repeat test to return a different result. Your nurse may note any values warranting further monitoring in your report.
4. Do I need to fast before a potency blood test?
Fasting is not always required, but testing in the morning — ideally between 7am and 10am — is recommended for testosterone as levels are naturally higher earlier in the day. Your clinic will advise you on specific preparation requirements.
5. Is a potency report the same as a fertility test?
Not exactly. A potency report focuses primarily on hormone levels, while a full fertility assessment may additionally include sperm analysis. Hormone results can, however, provide relevant context as part of a fertility health picture.
6. Who reviews my potency report results at Health Screening Clinic?
Health Screening Clinic is nurse-led. Our clinical nursing team prepares and presents your results clearly. We provide testing and reporting services; clinical interpretation and any resulting decisions about treatment or management should be made with an appropriate healthcare professional.
7. Can elevated prolactin on a potency report be serious?
Elevated prolactin in males may sometimes be associated with reduced libido or fertility concerns and can occasionally suggest other areas worth investigating. If your prolactin is notably elevated, we would always recommend discussing the result with a healthcare professional for further assessment.
8. What should I do if my results fall outside the reference range?
Review your full report in context, note any markers highlighted by the clinic, and arrange a consultation with your GP or an appropriate clinician. They can assess your results alongside your medical history and advise on whether further investigation is needed. If you are experiencing severe symptoms, please seek urgent medical care.
9. How do I book a potency screening test at Health Screening Clinic?
You can book directly through our website at healthscreeningclinic.co.uk. Our team will confirm what the test includes and how your results will be delivered.
10. Can lifestyle changes affect my potency report results?
Yes. Weight management, improved sleep, reduced alcohol intake, and regular physical activity may all support hormonal health. That said, lifestyle factors alone will not always resolve clinically significant imbalances, and professional advice remains important.
