Common questions

Everything you need to know before ordering your Erectile Dysfunction Blood Test.

What does this test check?

This profile checks 10 key markers that can contribute to erectile difficulties: testosterone (total and free), SHBG, prolactin, thyroid function (TSH, FT4), cholesterol, HbA1c (diabetes risk) and PSA (prostate health). It looks for the physical causes that underlie most cases of ED.

Why test blood for erectile dysfunction?

Most cases of ED have a physical rather than psychological cause. Low testosterone, thyroid dysfunction, diabetes, raised cholesterol and hormonal imbalances are all common contributors. Identifying the underlying cause means treatment can be targeted rather than generic.

Do I need to fast or prepare?

Follow these steps:

  • Avoid fatty foods for 8 hours (for cholesterol accuracy)

  • Morning sample between 6 and 10 AM (for testosterone accuracy)

  • No vigorous exercise or cycling for 48 hours (affects PSA)

  • Avoid ejaculation for 48 hours (affects PSA)

Is this test confidential?

Completely. Your results are delivered through a secure online portal and reviewed personally by a GP. No information is shared with your NHS GP or anyone else without your explicit consent.

How will I receive my results?

Secure online results with a GP-written explanation from Brooksby Medical in 2 to 3 working days.

More about Brooksby

Is my report reviewed by a doctor?

Yes. Every Brooksby test comes with a written report from Dr James Coleman, a practising GMC-registered GP, who personally reviews your results in the context of your symptoms and explains what each marker means and what to do next. If anything in your report needs discussing, you can request an optional free follow-up from your account — though many people are happy with the written report alone.

How accurate are the results?

All samples are processed in UKAS-accredited UK laboratories — the same accreditation standard used by hospital laboratories. Your results are then personally reviewed by a qualified GP before your report is issued.

Who writes the reports?

Every report is written by Dr James Coleman, an experienced, GMC-registered GP — not generated by AI or written by non-medical staff.

How long do results take?

Most reports are ready within 2–3 working days of your sample arriving at the lab. You will receive an email when your report is ready in your secure portal.

Do I need a GP referral?

No. You can order directly without a referral. Brooksby Medical is a CQC-registered service, and every result is reviewed by a practising doctor.

Can I share my results with my NHS GP?

Absolutely. Your report is designed to be shared with any healthcare professional. Many of our patients bring their Brooksby report to their NHS GP appointment for further discussion.

What happens if something is abnormal?

Your doctor-written report will flag any abnormal results with clear explanations and recommended next steps. For significantly abnormal results, we'll contact you directly.

What is the difference between venous and fingerprick?

Fingerprick tests use a small lancet to collect drops of blood at home. Venous tests are drawn from a vein by a nurse or phlebotomist. Each test page specifies which is required.

Is my data kept private?

Yes. All data is handled in accordance with UK GDPR. Packaging is plain with no indication of contents. Results are sent securely to you only, not shared or sold.
