I see many men present due to elevated or high PSA levels as part of their regular health screening. Prostate-specific antigen (PSA) is a protein produced by secretory cells that line the prostate. A PSA test measures the concentration of this protein in a blood sample and is commonly used for prostate cancer screening in Singapore and to monitor prostate health.
A high PSA result does not automatically mean you have prostate cancer. High PSA results must be interpreted according to the context, considering age, health status, medications and recent physical activities. PSA can also be elevated by conditions such as benign prostatic hyperplasia (BPH) and inflammation of the prostate.
Similarly, a PSA result within the expected range does not completely rule out prostate cancer. Your result helps your doctor assess your risk and decide whether you need monitoring or further investigation.
A PSA test requires a single blood sample taken from a vein, usually in your arm. The blood draw itself takes only a few minutes, and the appointment can generally be completed in around five minutes.
You do not need to fast before the test. Results are typically available within one working day.
Your PSA result is then considered alongside factors such as your age, previous PSA readings, prostate health and family history rather than interpreted as a stand-alone cancer test.
Prostate cancer was the most commonly diagnosed cancer among men in Singapore from 2018 to 2022, accounting for approximately one in six male cancer diagnoses, according to the Singapore Cancer Registry.
Singapore does not have a national population-wide prostate cancer screening programme. Hence, whether and when to undergo PSA testing should take into account your age, family history, general health and personal preferences.
This makes prostate screening in Singapore a shared decision between you and your doctor, after discussing what PSA testing can detect as well as its limitations.
There are different reference ranges of PSA for various age groups of men.
A lower percentage of free PSA may indicate a higher likelihood of prostate cancer.
The larger the prostate, the more PSA it produces. This is common in men over 50.
Prostatitis can cause significant PSA spikes in younger or sexually active men.
While most prostate cancers express PSA, low levels do not rule out cancer, as more aggressive forms may produce less PSA. It is important to understand the context of the individual.
There is no single screening schedule that applies to every man. Your age, family history, health and previous PSA results help determine when testing should begin and how often it should be repeated.
For men at average risk, a discussion about PSA screening can generally begin from around age 50. An earlier discussion, from around age 40 to 45, may be appropriate if you have a strong family history of prostate cancer or a family history suggesting an inherited cancer risk, including certain breast or ovarian cancers.
If you are already being monitored for an elevated PSA or another prostate condition, your urologist may recommend more frequent testing based on your previous results.
For men undergoing routine screening, retesting intervals may range from around two to four years when risk is lower, while a shorter interval may be recommended when PSA or other risk factors require closer monitoring.
Several temporary factors can affect PSA, so preparing for the blood test can help reduce the chance of a misleading result.
Before your test:
If there is a temporary factor that may have affected your result, your doctor may recommend waiting and repeating the test.
A total PSA result is not always enough to determine whether further investigation is needed. Innovations like PSA density, PSA velocity, and the Prostate Health Index (phi) are being explored to improve cancer detection and minimise unnecessary biopsies.
PSA density compares your PSA level with the volume of your prostate. This helps assess whether an elevated PSA may partly reflect a larger prostate rather than cancer.
PSA velocity looks at how quickly PSA changes over time. Rather than focusing on one result, your doctor considers the pattern across multiple tests.
The Prostate Health Index (PHI) combines total PSA, free PSA and a form of PSA known as -2proPSA into a single score to provide additional information about prostate cancer risk.
A raised PSA does not automatically lead to a prostate biopsy.
Your doctor will first consider the PSA level alongside your age, previous readings, prostate size, medications, symptoms and factors that could have temporarily raised your PSA. The next step may then involve repeat testing, examination or imaging.
PSA can fluctuate between tests, so a single raised reading is not usually considered in isolation.
If this is your first raised PSA result, your doctor may recommend repeating the blood test after temporary or reversible causes such as infection, ejaculation or recent cycling have been excluded.
Your doctor may also perform a digital rectal examination (DRE) to assess the prostate for changes such as abnormal firmness or a lump. The DRE provides additional clinical information but does not diagnose prostate cancer on its own.
If your PSA remains elevated or other findings raise concern, imaging may be the next step.
Multiparametric MRI (mpMRI) allows your urologist to look for suspicious areas within the prostate before deciding whether a biopsy is required.
If the MRI and your overall risk indicate that a biopsy is appropriate, the images can help guide tissue sampling towards suspicious areas.
PSA test cost in Singapore can include more than the laboratory blood test itself, particularly when PSA testing forms part of a prostate screening consultation.
The cost of PSA testing in Singapore varies depending on the clinic and the assessments required. As a general guide:
A prostate screening consultation may include a review of your age, family and medical history, urinary symptoms, medications and previous PSA results. Your doctor can then advise whether you require examination, repeat PSA testing or further investigation.
Whether MediSave, an Integrated Shield Plan or corporate insurance applies depends on the reason for testing, your policy and the investigations or treatment required. Check your coverage with your insurer and the clinic before proceeding.
PSA screening is not simply about whether your result falls above or below a particular number. Your age, family history, previous PSA results, medications and overall health all affect how the result should be interpreted.
If you are considering screening, bring any previous PSA results and a list of your current medications to your consultation. Tell your doctor about any family history of prostate, breast or ovarian cancer.

A PSA test is a single blood test that measures prostate-specific antigen. A prostate screening is the wider assessment around it: a review of your age, family history, symptoms, medications and previous PSA results, often with a digital rectal examination and sometimes an ultrasound or uroflowmetry. The PSA result is interpreted in that context rather than on its own.
There is no single dangerous number. PSA rises naturally with age, so the expected upper range moves from about 2.5 ng/mL in your 40s to about 6.5 ng/mL in your 70s. A level above the range for your age, or one that rises quickly between tests, is a reason for further assessment, not a diagnosis. Very high levels make cancer more likely but still need confirmation with examination, MRI and, where indicated, biopsy.
Not necessarily. PSA can be raised by benign prostate enlargement, prostatitis, a urinary infection, recent ejaculation, cycling or a recent procedure. Your doctor will consider your age, prostate size and previous readings, and may repeat the test before deciding whether an MRI or biopsy is needed. Equally, a normal PSA does not completely rule out cancer.
No. A PSA test does not require fasting. It is a simple blood draw that takes a few minutes. To avoid a misleading result, avoid ejaculation for about 48 hours and cycling or vigorous pelvic exercise for 24 to 48 hours beforehand, and tell your doctor about any recent urinary infection or prostate procedure.
For men at average risk, the discussion usually starts around age 50. If you have a strong family history of prostate cancer, or a family history of certain breast or ovarian cancers, it may be appropriate to start from around 40 to 45. The decision is shared between you and your doctor.
Yes. A PSA blood test can be requested through a polyclinic or GP, and it is included in many health screening packages. If the result is raised, you will usually be referred to a urologist for further assessment. You can also book directly with a private urologist without a referral.
As a general guide, a PSA blood test alone costs around SGD 35 to 60, a first specialist consultation around SGD 170 to 250, and a prostate screening consultation or package around SGD 250 to 400, depending on the assessments included, such as ultrasound or uroflowmetry. Fees vary between clinics, so ask for an estimate when booking.
There is no fixed schedule for everyone. For routine screening at lower risk, PSA may be repeated every two to four years. If your PSA is raised, you have other risk factors or you are already being monitored for a prostate condition, your urologist may recommend yearly or more frequent testing.
The PSA blood test involves only a standard blood draw. A digital rectal examination, if performed, takes a few seconds and may feel briefly uncomfortable but is not usually painful. Ultrasound and uroflowmetry are painless.
