Should you get a PSA test? A prostate-specific antigen (PSA) blood test may help detect prostate cancer before symptoms appear, but it is not recommended as routine screening for everyone. Whether to test depends on your age, family history, personal risk factors, overall health and preferences.
At Lab On Demand in Indianapolis, we offer PSA blood testing alongside preventive health, wellness and longevity-focused laboratory services. Our goal is to make testing accessible while helping patients understand why a test may be useful and the importance of appropriate medical follow-up.
What is a PSA blood test?
A PSA test measures prostate-specific antigen, a protein produced by cells in the prostate gland.
PSA levels can increase for several reasons, including prostate cancer, benign prostate enlargement and inflammation.
An elevated PSA does not automatically mean you have prostate cancer. Likewise, a lower PSA level does not completely rule out cancer.
PSA testing may be used for three different purposes:
- Prostate cancer screening: Checking for possible cancer before symptoms develop.
- Diagnostic evaluation: Helping investigate symptoms or other concerning findings.
- Monitoring: Following PSA levels in someone previously diagnosed with prostate cancer.
These situations have different clinical considerations. If you have urinary symptoms, blood in your urine or other concerns, arrange a medical evaluation rather than relying on a screening test alone.
At what age should you consider PSA screening?
Medical organizations provide somewhat different recommendations, but they agree that the decision should consider individual risk and potential harms.
The U.S. Preventive Services Task Force recommends shared decision-making for men ages 55–69 and recommends against routine PSA screening for men age 70 and older.
The American Cancer Society recommends offering an informed screening discussion at different ages according to risk.
| Age | Screening discussion |
|---|---|
| 40 | May be appropriate for those at especially high risk, such as men with multiple first-degree relatives diagnosed at an early age |
| 45 | Recommended discussion age by the American Cancer Society for higher-risk men, including Black men and men with certain family histories |
| 50 | Recommended discussion age for average-risk men expected to live at least 10 more years |
| 55–69 | USPSTF recommends an individualized decision after reviewing benefits and harms |
| 70+ | USPSTF recommends against routine PSA-based screening |
These are not universal instructions to undergo testing at a particular age.

What are the benefits and risks of PSA screening?
The potential benefit of PSA screening is identifying some clinically significant prostate cancers earlier, when treatment may be more effective.
However, screening also has limitations.
An elevated result may lead to repeat blood tests, imaging or prostate biopsy. Some elevated results occur without cancer. Screening may also detect slow-growing cancers that would never have caused symptoms, leading to unnecessary treatment.
Potential treatment complications include urinary incontinence and erectile dysfunction.
Before testing, ask your healthcare professional:
- What is my individual risk of prostate cancer?
- How likely am I to benefit from screening?
- What would happen if my PSA were elevated?
- How would we decide whether additional testing is necessary?
Understanding these questions before the blood draw helps make screening a more informed decision.
What does a high PSA result mean?
A high PSA result means the measured concentration of prostate-specific antigen is elevated relative to the laboratory reference range or the clinical threshold being considered.
It does not establish a cancer diagnosis.
Several factors can affect PSA levels, including:
- Benign prostate enlargement
- Prostate inflammation or infection
- Recent prostate procedures
- Certain medications
- Ejaculation or vigorous cycling close to testing in some circumstances
A clinician may recommend repeating the PSA test or arranging additional evaluation before deciding whether imaging or biopsy is appropriate.
There is no single PSA cutoff that reliably distinguishes cancer from noncancerous conditions in every patient.
How should you prepare for a PSA blood test?
A PSA test requires a blood sample and generally does not require fasting when performed alone.
Before testing, tell your healthcare professional about medications, supplements, recent urinary symptoms, prostate procedures and any previous PSA results.
Your clinician may recommend avoiding ejaculation or certain activities shortly before the test, depending on the circumstances.
Do not discontinue prescribed medications without medical guidance.
At Lab On Demand, confirm the preparation requirements for your specific order before your appointment, especially if you are combining PSA testing with other laboratory tests.
How does PSA testing fit into preventive health and longevity testing?
PSA testing addresses a specific prostate-health question. It is not a comprehensive measure of longevity, biological age or overall cancer risk.
However, when clinically appropriate, PSA testing may be one part of a broader conversation about preventive health.
At Lab On Demand in Indianapolis, we provide laboratory testing for people interested in monitoring established health markers, managing existing conditions and discussing long-term wellness with their healthcare professionals.
Preventive and longevity-focused laboratory testing at Lab On Demand
Our testing menu includes options such as:
Cardiovascular and metabolic health
- Lipid panels to assess cholesterol and triglycerides
- Hemoglobin A1c to evaluate average blood glucose
- Comprehensive metabolic panels to assess selected kidney, liver and metabolic markers
Hormonal and men’s health
- Testosterone testing
- Thyroid-function testing
- Men’s health laboratory profiles
- PSA testing when clinically appropriate
Nutrition and general wellness
- Vitamin D testing
- Nutritional health profiles
- Other individualized laboratory testing options
These tests may provide useful information when selected for a specific clinical purpose and interpreted in context.
More testing does not necessarily mean better preventive care. Not every biomarker needs routine measurement, and some tests can lead to incidental findings or unnecessary follow-up.
For people interested in longevity, laboratory results are most useful when combined with evidence-based preventive care, appropriate cancer screening, blood-pressure assessment, physical activity, nutrition and individualized medical advice.

Is PSA testing part of an immigration medical exam?
Lab On Demand also provides laboratory services associated with USCIS immigration medical examinations (Form I-693) in Indianapolis.
However, PSA screening is not a routine requirement of the standard I-693 immigration medical examination.
Immigration medical examinations follow separate USCIS requirements and CDC Technical Instructions, which may include tuberculosis screening, syphilis testing, gonorrhea testing and vaccination assessment, depending on the applicant.
PSA testing and longevity-focused laboratory testing are separate services that should not be confused with required immigration screening.
For immigration-specific services, visit our I-693 immigration medical exam page.
Frequently asked questions about PSA testing
Should every man over 40 get a PSA test?
No. Routine PSA screening is not recommended for every man over 40. Earlier discussions may be appropriate for people with increased risk, including certain family histories or inherited genetic variants.
Is a PSA blood test painful?
The test involves a routine blood draw. You may experience brief discomfort or minor bruising at the collection site.
Can PSA testing detect prostate cancer early?
PSA screening can help identify some prostate cancers before symptoms develop, but it cannot independently diagnose cancer and can produce false-positive or false-negative results.
Is PSA the same as a testosterone test?
No. PSA measures a prostate-related protein, while testosterone testing measures a hormone. The tests serve different purposes.
Can I combine PSA testing with other blood tests?
Yes, multiple laboratory tests can often be collected during the same visit when appropriately ordered. However, whether you need a PSA test, lipid panel, A1c or hormone testing should depend on your individual circumstances.
Does a normal PSA mean I do not have prostate cancer?
No. A normal or lower PSA does not completely exclude prostate cancer. Your healthcare professional considers the result alongside your symptoms, history and risk factors.
