About the Free PSA Blood Test

Prostate Specific Antigen (PSA) is a protein that is produced by the prostate. Although the protein is produced by healthy prostate cells, levels can rise if there is a problem with the prostate, particularly in prostate cancer.

PSA is a useful screening test for prostate cancer but it is not perfect so you should be aware of its shortcomings. Many men will have a high PSA but not have prostate cancer. Testing the PSA in these men can result in them having invasive procedures, such as a prostate biopsy, when there is actually no problem. Similarly, some men will have a "false negative" result – a normal PSA when there actually is underlying cancer. For this reason, even if your PSA is normal, you should still see a doctor if you have symptoms such as difficulty passing urine, getting up lots at night to pee, or feel that you are not emptying your bladder properly.

There are two biomarkers that can be measured in PSA - the total PSA level and the free PSA level. The total PSA test measures the total amount of PSA in the blood, including both bound and unbound forms. The free PSA test measures only the unbound, or free, PSA in the blood. It is important to have both of these biomarkers measured. 

This is the test to measure FREE PSA. You can find the test for TOTAL PSA here. Or check out the Ultimate PSA Blood Test that measures both the free and the total levels of PSA.

The ratio of these two markers can be a very good indicator for your GP as to what is happening and the likelihoods of current or future issues. This is calculated by dividing Free PSA by Total PSA and multiplying by 100, giving the Free to Total PSA ratio as a percentage.

    - Free PSA


    You can measure the Total PSA here, or check out the Ultimate PSA Blood Test that measures both free and total, as well as the ratio.


    This test has a longer turnaround time than our usual "same/next day". The nature of the test is such is that it takes time to prepare and analyse. Specifically the turnaround time is:

    - 3 days

Doctor's notes

Hi, I am Dr. Adam Staten and here's my view on this test as a GP and Clinical Director at One Day Tests.

The Free PSA blood test can be a valuable tool in detecting prostate cancer and other prostate-related conditions.

However, it is important to note that a high level of PSA in the blood does not necessarily mean that prostate cancer is involved.

Other factors, such as age, ethnicity, and certain medications, can also affect PSA levels and it is absolutely vital that you follow up your results with your GP.

Red flag symptoms for the Free PSA Blood Test

Even if your blood tests are normal, you should see a doctor if you have any of the symptoms below because they may be a sign of serious underlying illness. 

  • Frequent urination
  • Pain ejaculating
  • Blood in semen or urine
  • Progressively severe symptoms of any kind

Your Results and Health Dashboard

The results of your Free PSA Blood Test will be emailed to you as a secured PDF file, ready for your GP and will also be uploaded to our Health Dashboard area of the website. It’s a unique and powerful tool, powered by our in-house clinical analysis research, to match your biomarkers across test panels and symptoms, as well as provide clinical commentary on all individual biomarkers you tested for.

The health dashboard will also provide "panel level" commentary - a birds eye view of the biomarkers that were tested. This feature allows you to view your test results and clinical commentary, and compare them to previous results, giving you a clear understanding of how your health is progressing.

By using the Health Dashboard, you can identify changes in your biomarkers and make necessary adjustments to your lifestyle. This added value is immense, as it empowers you to monitor your health and make informed decisions about your well-being.

It's free and is available with all of our tests.

Special instructions

Hi, I am Stefania Brown, I am the Laboratory Manager at One Day Tests and here are the lab's special requests for the Free PSA Blood Test.

For the 48 hours before having a PSA test:

  • avoid sexual activity as ejaculation as it may raise PSA levels significantly (but temporarily).
  • avoid vigorous exercise in the previous 48 hours.
  • you do not have an active urinary infection (PSA may remain raised for many months)
  • you have not had a prostate biopsy in the previous 6 weeks

Venepuncture appointment - how to prepare

If you are coming into one of our clinics for the test, this is what you need to do before you arrive:

  • Drink plenty of water about an hour before the appointment.
  • Avoid coffee/tea/energy drinks. Water is good!
  • That’s it! We’ll do the rest.

Home test kit for Free PSA Blood Test - how it works

Our blood test kits are simple and convenient.

The most important step in doing a blood test at home is to read the instructions very carefully. The process is very simple, but there are a few pitfalls you need to be aware of - you will save yourself a lot of time if you do it right the first time around!

  • Full printed instructions will arrive with your kit - please read them carefully.
  • Drink plenty before taking the sample and warm your hands up in the sink with warm water for a few minutes. This will make your blood flow much better.
  • Fill the tubes to the top line. We don’t need much blood; filling tubes to the top line is about 15 drops of blood.
  • Post the samples on the same day you take them, before midday, Monday to Thursday. If you post it any other time it might get to us late or be stuck at a sorting office over the weekend. You will then have to do it again.
  • Package the sample in the same box the kit came in. Otherwise, Royal Mail or DPD will reject it. The sample tubes go into a pouch, then into a cardboard box, and then into a return envelope. All of this is provided in the kit: please use it.

We look forward to receiving your sample in our lab!
