What is a Total PSA Test?

A Total PSA test is a simple blood test to check prostate cancer risk by measuring the total amount of Prostate Specific Antigen (PSA) in your bloodstream. PSA is a protein naturally produced by the prostate gland, and while it is normal to have some present, elevated PSA antigen levels can suggest changes in the prostate. These changes may be due to benign conditions such as prostate enlargement or inflammation, but in some cases they may be an early indicator of prostate cancer.

 

The PSA blood test has become one of the most important tools in men’s health for checking PSA levels and supporting early prostate cancer diagnosis. Although it is not a standalone test, it plays a key role in prostate screening programmes and can guide further investigations when needed.

 

Many men choose a PSA screen test for peace of mind, especially if they have a family history of prostate cancer or are experiencing urinary symptoms. Quick and straightforward, the prostate PSA test offers valuable insights that allow doctors to make informed decisions about your prostate health.

 

At Medilabs in London, we provide accurate PSA blood checks with rapid results, giving you clarity and helping you stay in control of your wellbeing.

Benefits of a Total PSA Blood Test

Benefits of a Total PSA Blood Test

 

Taking a Total PSA test is a simple step that can make a big difference to your long-term prostate health. While the test alone cannot confirm prostate cancer, it provides crucial information about your PSA antigen levels and overall prostate function. Here are the key benefits explained in detail:

 

·     Early Detection of Prostate Cancer

The most recognised benefit of the PSA cancer blood test is its ability to highlight prostate cancer risk before noticeable symptoms develop. Cancers detected early are often smaller, confined to the prostate, and easier to treat effectively.This means a simple PSA screen test could lead to life-saving early intervention.

 

·     Ongoing Monitoring of Prostate Health

Tracking PSA readings over time gives a clearer picture of prostate health than a single test result. Repeated PSA blood checks can identify upward trends that may indicate gradual changes, prompting timely follow-up investigations and preventing delays in care.

 

·     Supports Accurate Prostate Cancer Diagnosis

While a raised PSA level doesn’t always mean cancer, it acts as a red flag that helps guide further diagnostic steps such as MRI scans or biopsies. In this way, the prostate PSA test works as an important first filter in the prostate cancer diagnosis process.

 

·     Simple and Minimally Invasive Procedure

Unlike other diagnostic procedures that can feel uncomfortable, the PSA blood test is quick and minimally invasive. A small blood sample is all that is required, with results usually available within a short timeframe. This makes it a practical choice for routine PSA screening.

 

·     Provides Reassurance and Peace of Mind

For many men, taking a blood test to check prostate cancer risk offers reassurance. A normal PSA reading can help ease worries, while an abnormal result provides clarity and direction for next steps. Either way, it empowers you with knowledge about your health.

 

·      Detects Other Prostate Conditions Early

Raised PSA antigen levels are not always linked to cancer. They can also be a sign of non-cancerous conditions such as prostatitis (inflammation) or benign prostatic hyperplasia (enlargement). Detecting these early through a PSA blood test allows prompt treatment and better symptom management.

 

·     Helps Monitor Treatment Effectiveness

For men already diagnosed with prostate conditions, regular checking PSA levels can help monitor how well treatment is working. Falling PSA levels often indicate successful management, while rising levels may suggest the need to adjust the treatment plan.

 

·     Widely Recognised and Reliable Screening Tool

The PSA screening test is widely used worldwide, supported by medical professionals and healthcare guidelines. Its accessibility and reliability make it one of the most trusted tools in men’s health for monitoring and protecting prostate wellbeing.

 

At Medilabs, our PSA blood test service combines accuracy with compassionate care. Whether you are seeking reassurance, investigating symptoms, or monitoring ongoing treatment, we provide clear results and guidance to help you make informed decisions about your health.

Step-by-Step at Medilabs

1

Booking Your Appointment
You can easily book your PSA screen test online or by phone at a time that suits you. Our team will confirm your appointment and answer any initial questions about the blood test to check prostate cancer risk.

2

Pre-Test Guidance
Before your visit, we’ll provide you with preparation advice to ensure your PSA reading is as accurate as possible. This may include avoiding certain activities, such as vigorous exercise, or recent medical procedures that could temporarily affect PSA antigen levels.

3

Professional Blood Collection
During your appointment, one of our experienced clinicians will take a small blood sample from your arm. The process is quick, minimally invasive, and carried out in a professional, comfortable environment. This is the key step in checking your PSA levels.

4

Laboratory Analysis
Your sample is then sent to our accredited laboratory, where it is carefully analysed to measure your Total PSA antigen levels. Advanced testing methods ensure precision and reliability, so your PSA cancer blood test results are dependable.

5

Results and Next Steps
Once the results are ready, you’ll receive them promptly, along with clear guidance on what your PSA screening outcome means. If your PSA levels are within the normal range, you’ll gain reassurance. If raised, we will advise on appropriate follow-up steps and support you in discussing further investigations with your GP or specialist.

Understanding Your PSA Results

Your PSA blood test results will show your PSA antigen levels in nanograms per millilitre (ng/mL) of blood. Interpreting these results requires context, as PSA readings can be influenced by age, prostate size, and other health conditions.

 

Typical UK Reference Ranges for PSA (Total PSA)

  • Age 50–59: Up to 3.0 ng/mL
  • Age 60–69: Up to 4.0 ng/mL
  • Age 70–79: Up to 5.0 ng/mL

 

It is important to note that values below these thresholds are generally considered within the normal range, while higher PSA levels may suggest further investigation is needed.

 

What Different PSA Readings May Indicate

 

  • Normal PSA levels: Usually indicate healthy prostate function, though regular PSA screening may still be advised, especially if you are in a higher risk group.
  • Slightly raised PSA: May be due to benign causes such as prostatitis (inflammation) or benign prostatic hyperplasia (BPH). These conditions are not cancerous but can still cause uncomfortable urinary symptoms.
  • Significantly raised PSA: Can be a potential warning sign of prostate cancer and may require additional tests such as MRI, biopsy, or referral to a specialist.

 

Important Considerations

 

A raised PSA reading does not always mean cancer. Likewise, a normal PSA blood check does not completely rule it out. That’s why the PSA screen test is used as part of a wider prostate cancer diagnosis process, rather than in isolation.

 

At Medilabs, your results are presented clearly and with full explanation, so you understand exactly what they mean for your prostate health. Where needed, we guide you on the appropriate next steps and encourage follow-up with your GP or urologist.

Preparation

·     Avoid Vigorous Exercise

Strenuous physical activity, especially cycling, running, or gym workouts, can temporarily raise PSA antigen levels. It’s best to avoid such activities for at least 48 hours before your PSA blood test.

 

·     Refrain from Ejaculation

Sexual activity can affect PSA levels, leading to misleading results. For the most reliable outcome, avoid ejaculation for 48 hours before your PSA screen test.

 

·     Schedule Around Medical Procedures

If you’ve recently had a digital rectal examination, prostate biopsy, or urinary catheterisation, wait at least 6 weeks before taking a blood test prostate PSA, as these procedures may elevate PSA readings.

 

·     Inform Us About Medications

Certain medications, such as those used for urinary symptoms or prostate enlargement, may lower PSA levels artificially. Let our team know about any treatments you’re taking before your PSA blood check.

 

·     Stay Hydrated and Relaxed

Drink plenty of water before your test, and try to remain calm. Stress and dehydration won’t drastically affect PSA screening, but being well-prepared helps make the blood draw quicker and more comfortable.

Aftercare

·     Apply Gentle Pressure

If you experience mild bruising at the blood draw site, apply gentle pressure with a clean cotton pad. This helps reduce discomfort and swelling.

 

·     Stay Hydrated

Drinking water helps your body recover quickly after any blood test, including a PSA cancer blood test, and supports healthy circulation.

 

·     Avoid Heavy Lifting with the Arm Used

If your arm feels sore, avoid heavy lifting or strenuous exercise with that arm for the rest of the day to reduce bruising or irritation.

 

·     Monitor for Side Effects

Most men feel completely fine after a PSA blood test. If you notice prolonged bruising, swelling, or unusual discomfort at the injection site, let our team or your GP know.

 

·     Review and Act on Your Results

Once your PSA levels are available, take time to review them carefully. At Medilabs, we provide clear explanations of what your PSA screen test means and advise whether further steps in the prostate cancer diagnosis pathway are needed.
