PSA Test

The PSA (prostate-specific antigen) test is a simple blood test that measures a protein made by the prostate gland. It is used to screen for prostate cancer, monitor treatment, or investigate symptoms like difficulty urinating — but it does not, by itself, diagnose cancer. This guide explains what the test measures, how to prepare, what your results mean, and what you can expect in Bangladesh.

What Is a PSA Test and What Does It Measure?

PSA stands for prostate-specific antigen, a protein produced by both normal and cancerous cells of the prostate gland. The test measures the total amount of this antigen in your bloodstream — both free (unbound) and bound to other proteins.

The test has three main uses:

• Screening for prostate cancer in men at higher risk (over 50, or 45 with a family history).
• Monitoring men on active surveillance (low-risk cancer) or to observe response to treatments like surgery, radiation, or hormone therapy.
• Investigation of urinary symptoms such as a weak stream, frequent urination, or trouble starting/stopping.

How Is the PSA Test Done? Do I Need to Prepare?

The PSA test requires a single blood draw, usually from a vein in your arm. It is a routine procedure, done in a pathology lab or hospital clinic, and takes about a minute. No fasting, water restrictions, or other special preparation is typically needed.

However, certain activities can temporarily raise your PSA level. To avoid a false elevation:

• Avoid ejaculation for at least 48 hours before the test.
• Avoid heavy exercise (especially cycling) on the day before testing.
• Postpone the test if you have had a digital rectal exam (DRE), prostate biopsy, or catheter insertion within the past 2–4 weeks.
• If you have a urinary tract infection or acute prostatitis, men should first treat the infection and then retest after 4–6 weeks.

What Do My PSA Results Mean? Understanding the Numbers

There is no single ‘normal’ cutoff for PSA. Values increase naturally with age because the prostate gland grows. Doctors use age-adjusted ranges to help interpret results — but they are not absolute; trends over time matter more.

Age-Adjusted PSA Reference Ranges (approximate)

Age group	Typical PSA range (ng/mL)	Notes
40–49	0 – 2.5	Lower level; cancer unlikely below 2.5
50–59	0 – 3.5	Gray zone — raise for further evaluation if >3.5
60–69	0 – 4.5	Common range; 4.0 is typical cutoff but not strict
70+	0 – 6.5	Higher due to BPH; shared decision-making needed

A single elevated result is not a diagnosis of cancer. Your doctor will likely repeat the test after a few weeks and may check a free/total PSA ratio to improve accuracy. Only a prostate biopsy can confirm cancer. Also, some medications (e.g., finasteride, dutasteride) lower PSA by about 50% — tell your doctor about any medicines you take.

What Factors Can Raise (or Lower) PSA Levels?

PSA can rise due to prostate cancer, but also due to several other factors. This is why a high result does not automatically mean you have cancer.

• Benign prostatic hyperplasia (BPH) — a non-cancerous enlargement of the prostate, common with age.
• Prostatitis — inflammation or infection of the prostate, often causing pain.
• Urinary tract infection (UTI) — infection anywhere in the urinary system.
• Recent catheter or procedures — even a DRE can temporarily raise levels.
• Heavy exercise — especially cycling, due to pressure on the perineum.
• Ejaculation within 48 hours — it can cause a moderate, temporary rise.

Factors that lower PSA include: certain 5-alpha-reductase inhibitors (finasteride/dutasteride), aspirin, and diuretics — always disclose your medications to your doctor.

How Much Does a PSA Test Cost in Bangladesh?

Prices vary by lab quality, location (Dhaka vs. other cities), and whether the test is is included in a package. The cost ranges below are approximate and can change — always confirm before booking.

PSA Test Cost in Bangladesh (Private Labs & Hospitals)

Item	Approx. BDT range	Notes
PSA (total) alone	500–1,500	Basic labs; lower in smaller cities
PSA with free/total ratio	1,500–3,000	Better specificity; not all labs offer
Part of comprehensive health package (including PSA, CBC, etc.)	3,500–6,000	Often done at screening events

Prices change over time. Always call the lab or visit their office to confirm current rates. Most private labs (e.g., Popular, Medinova, Ibn Sina, Square) and hospital-based pathology departments in Dhaka offer the test.

What Are the Limitations of the PSA Test?

The PSA test is a useful screening tool but has important shortcomings you should know:

• High false-positive rate — many elevated PSA levels will be due to BPH or infection, not cancer, which can cause worry and unnecessary further tests.
• Overdiagnosis — the test often detects slow-growing cancer (low-grade) that might never cause a problem, yet is treated with aggressive treatment.
• Overtreatment — many men who are diagnosed due to a high PSA may then receive surgery or radiation that can cause leftover effects (such as urinary incontinence, erectile dysfunction) that outweigh the benefit.
• Not cancer-specific — cancer is only confirmed by biopsy; the test does not measure how dangerous a you may have.

To address these limitations, doctors may use the free-to-total PSA ratio, PSA velocity (change over time), or newer markers like PHI (prostate health index). These are not widely available in Bangladesh but are offered at some major private hospitals.

When Should You See a Urologist?

You should see a urologist if:

• Your PSA is persistently elevated or rising over a repeat test.
• You have urinary symptoms — weak stream, frequent urination, blood in urine or semen, pelvic pain.
• You are between 50–70 years old and considering screening — discuss risks and benefits first.
• You are 45+ with a family history of prostate cancer (father, brother).

During the consultation, your doctor will review your history, perform a digital rectal exam (DRE), and may order a repeat PSA or free PSA. If the assessment raises concern, a prostate biopsy may be discussed.

Frequently Asked Questions

Can a normal PSA level still mean I have prostate cancer?

Yes. A normal PSA level (typically below 4 ng/mL) does not completely rule out prostate cancer. Some aggressive cancers produce little PSA, and some men with cancer have levels within the normal range. Conversely, a high PSA does not always mean cancer. That is why doctors rarely rely on PSA alone — they consider your age, family history, digital rectal exam findings, and sometimes repeat testing or imaging before deciding on a biopsy.

Should I stop taking my medicines before a PSA test?

Certain medications can lower PSA levels and may give a falsely reassuring result. Common examples include finasteride (for hair loss) and dutasteride (for enlarged prostate). If you take any of these, tell your doctor before the test. Do not stop any medication on your own — your doctor will advise whether to pause it and for how long. Other drugs like NSAIDs or statins have less clear effects, but always disclose your full medicine list.

What happens if my PSA is high — do I need a biopsy right away?

Not immediately. A single high PSA value is not a diagnosis. Your doctor will usually repeat the test after a few weeks, especially if you had an infection, recent ejaculation, or a long bike ride before the first test. If the level remains high, the next step is often a multiparametric MRI of the prostate, which can show suspicious areas. A biopsy is only recommended if both PSA and MRI suggest significant risk. This stepwise approach reduces unnecessary biopsies.

Is the PSA test covered by health insurance in Bangladesh?

Coverage varies by insurer and policy. Many private health insurance plans in Bangladesh cover the PSA test as part of routine health check-ups or when ordered by a specialist. However, some plans may require pre-authorization or only cover it for men over a certain age (e.g., 50+). It is best to check with your insurance provider directly or ask the hospital billing department before the test. Out-of-pocket cost is generally low (see the article for price range).

Can I get a PSA test at a diagnostic center without a doctor’s prescription?

In Bangladesh, most diagnostic centers and hospitals require a doctor’s prescription for a PSA test. This is a safety measure to ensure the test is clinically indicated and that results are interpreted by a qualified physician. While a few centers may allow self-requested testing, it is strongly discouraged — without proper context, a PSA result can cause unnecessary anxiety or false reassurance. Always consult a urologist first.
