Men's Health After 40: The Tests Worth Discussing With Your Doctor

Turning 40 does not trigger one universal panel of medical tests.

It does mark a useful point to review your cardiovascular risk, family history, cancer-screening schedule, sleep, sexual health, and metabolic health. Several conditions become more common in midlife, and many develop before you notice symptoms.

The right plan depends on more than age. A 42-year-old man with a father who had a heart attack at 48 needs a different conversation than a 42-year-old with no family history, normal blood pressure, and no history of smoking.

Here are the tests worth discussing with your doctor, including the ones that should be routine and the ones that only make sense under specific circumstances.

Men's Health Screening by Age and Risk

This table provides a starting point. Your doctor may recommend earlier, later, or more frequent testing based on your history.

1. Blood Pressure: The Basic Measurement That Needs to Be Accurate

High blood pressure often causes no symptoms. It can still increase your risk of stroke, heart disease, kidney disease, and other complications.

The U.S. Preventive Services Task Force recommends screening every adult for hypertension. It suggests annual screening for adults 40 and older and for younger adults with increased risk.[1]

One high reading in an exam room does not automatically establish a diagnosis. Stress, caffeine, recent exercise, pain, talking during the measurement, and an incorrectly sized cuff can affect the result.

If your office reading is elevated, ask about confirming it with:

• A validated home blood-pressure monitor

• Measurements taken at different times over several days

• A 24-hour ambulatory monitor when appropriate

• A review of medications and supplements that may raise blood pressure

Bring the actual readings to your appointment. "It runs high sometimes" gives your doctor less information than a seven-day log showing morning readings around 138/86 and evening readings around 128/80.

2. Cholesterol Testing: Start With the Standard Panel

A standard lipid panel typically includes:

• Total cholesterol

• Low-density lipoprotein cholesterol

• High-density lipoprotein cholesterol

• Triglycerides

Your doctor should interpret those numbers alongside age, blood pressure, smoking status, diabetes, kidney function, family history, and other risk factors. A low-density lipoprotein cholesterol result cannot describe your entire cardiovascular risk by itself.

The 2026 American College of Cardiology and American Heart Association cholesterol guideline recommends using the PREVENT calculator to estimate 10-year and 30-year cardiovascular risk in adults ages 30 to 79.[2]

That calculation can help you and your doctor decide whether lifestyle changes alone are reasonable or whether cholesterol-lowering medication deserves consideration.

Lipoprotein(a) Is Now Worth a One-Time Discussion

The same 2026 guideline recommends measuring lipoprotein(a) at least once in adulthood. Lipoprotein(a), often written as Lp(a), is a largely inherited particle associated with cardiovascular risk.[2]

A high result does not establish that you have heart disease. It may support closer attention to low-density lipoprotein cholesterol and other modifiable risks.

This test may be especially relevant if:

• A parent or sibling had an early heart attack or stroke

• Your family has very high cholesterol

• You developed cardiovascular disease despite otherwise ordinary cholesterol results

• Your calculated risk and family history seem inconsistent

Apolipoprotein B and Coronary Calcium Require More Context

Apolipoprotein B can help estimate the number of cholesterol-carrying particles that may enter artery walls. Doctors may consider it when triglycerides are elevated, metabolic disease is present, or the standard panel leaves uncertainty.

A coronary artery calcium scan uses computed tomography to look for calcified plaque. The 2026 guideline says calcium scoring can improve risk assessment in men 40 and older, but that does not make it a routine test for every man over 40.[2]

It has greater value when the result could change a decision about preventive treatment. Ask your doctor what each possible score would change before scheduling the scan.

3. Blood Sugar: Diabetes Can Develop Before Symptoms Appear

Blood glucose testing may use:

• Fasting plasma glucose

• Hemoglobin A1C

• An oral glucose-tolerance test

Hemoglobin A1C estimates average blood sugar over approximately two to three months. A fasting glucose measures one point in time.

The U.S. Preventive Services Task Force recommends screening adults ages 35 to 70 who have overweight or obesity for prediabetes and type 2 diabetes.[3]

Screening may begin earlier or occur more often when other risks are present, including:

• A parent or sibling with diabetes

• High blood pressure

• Abnormal cholesterol or triglycerides

• Limited physical activity

• Certain medications

• Previous evidence of elevated blood sugar

• Membership in a population with a higher prevalence of diabetes

Ask what your result means in context. A single mildly abnormal value may need confirmation, and changes over several years can be more informative than one isolated measurement.

4. Colorectal Cancer Screening Starts at 45

Average-risk adults should begin colorectal cancer screening at age 45 and continue through age 75. Screening after 75 becomes an individual decision based on health, previous screening, and preferences.[4]

You have several options. They include:

• A fecal immunochemical test every year

• A stool DNA and fecal immunochemical test every one to three years

• Computed tomography colonography every five years

• Colonoscopy every ten years

• Other combinations involving sigmoidoscopy and stool testing

A positive stool-based test usually needs follow-up with a colonoscopy.

Some men need an earlier or different plan. Tell your doctor if you have a parent, sibling, or child with colorectal cancer or an advanced polyp. Also report blood in the stool, unexplained iron-deficiency anemia, persistent changes in bowel habits, or unexplained weight loss. Those symptoms require evaluation rather than routine screening.

The best screening method is one you can complete correctly and repeat at the recommended interval.

5. Prostate Cancer Screening Requires an Individual Decision

The prostate-specific antigen test measures a protein produced by prostate tissue. An elevated result can occur with prostate cancer, an enlarged prostate, inflammation, infection, recent procedures, and other conditions.

Under the current final U.S. Preventive Services Task Force recommendation, men ages 55 to 69 should make an individual decision about prostate-specific antigen screening after discussing potential benefits and harms with a clinician. Routine screening is not recommended for men 70 and older.[5]

The Task Force is updating this recommendation, so the exact age guidance may change.

A prostate-specific antigen test can identify some cancers earlier. It can also lead to:

• False-positive results

• Repeat blood tests

• Magnetic resonance imaging

• Prostate biopsy

• Diagnosis of a cancer that might never cause symptoms

• Treatment side effects, including urinary incontinence and erectile dysfunction

Your risk discussion should include family history and ancestry. Men with a father or brother who developed prostate cancer, especially at a younger age, may need to begin the conversation earlier.

Ask three questions before testing:

1. What is my individual risk?

2. What would we do with an elevated result?

3. How would my preferences affect the next step?

6. Lung Cancer Screening Is for Men With a Specific Smoking History

A routine chest X-ray does not serve as the recommended screening test for lung cancer.

The U.S. Preventive Services Task Force recommends an annual low-dose computed tomography scan for adults who meet all three criteria:[6]

• Age 50 to 80

• At least a 20 pack-year smoking history

• Currently smoke or stopped within the past 15 years

One pack-year means smoking an average of one pack per day for one year. Smoking one pack per day for 20 years or two packs per day for 10 years both equal 20 pack-years.

Screening can produce false-positive findings and may identify abnormalities that require additional imaging. The decision should include a discussion of benefits, limitations, and your ability to undergo treatment if cancer is found.

Anyone who currently smokes should also receive help quitting. Screening cannot replace smoking cessation.

7. Testosterone Testing Makes Sense When Symptoms Are Present

Fatigue, weight gain, reduced exercise performance, low mood, erectile dysfunction, and reduced sexual interest can occur for many reasons. Sleep deprivation, depression, medication effects, obesity, diabetes, alcohol use, thyroid disease, relationship problems, and sleep apnea can produce overlapping symptoms.

The Endocrine Society recommends against routine testosterone screening in the general male population. A diagnosis of hypogonadism requires compatible symptoms plus consistently low testosterone measurements.[7]

If testing is appropriate, the Society recommends confirming a low result with a second early-morning, fasting measurement. Its July 2026 statement describes a commonly used clinical threshold near 300 nanograms per deciliter while emphasizing that assay quality, symptoms, and repeat testing matter.[8]

If both results are low, further testing may help determine whether the cause involves the testicles, pituitary gland, medication use, obesity, chronic disease, or another condition.

Testosterone therapy also requires a discussion of:

• Fertility plans

• Prostate monitoring

• Red blood cell count

• Cardiovascular history

• Untreated severe sleep apnea

• Treatment goals

• Long-term safety uncertainties

A single afternoon testosterone result should not become the basis for lifelong treatment.

8. Sleep Apnea Evaluation Can Be More Useful Than Another Blood Panel

Consider discussing sleep apnea if you:

• Snore loudly

• Wake up gasping or choking

• Have witnessed pauses in breathing

• Wake with headaches or a dry mouth

• Feel sleepy while driving or working

• Have difficult-to-control high blood pressure

• Sleep for seven or eight hours but remain exhausted

The U.S. Preventive Services Task Force found insufficient evidence to recommend population-wide screening in adults without recognized symptoms. That conclusion does not apply to people who report symptoms or concerns that suggest sleep apnea.[9]

Your doctor may begin with a history, physical examination, and structured risk assessment. Some patients can complete a home sleep-apnea test. Others need an overnight study in a sleep laboratory.

This is an example of why a symptom review matters. A broad laboratory panel may fail to explain fatigue when interrupted breathing is the underlying problem.

9. One-Time Infection Screening Is Easy to Miss

The U.S. Preventive Services Task Force recommends hepatitis C screening for adults ages 18 to 79. For most adults, this is a one-time blood test. People with continued exposure risk may need repeat testing.[10]

The Task Force also recommends human immunodeficiency virus screening for adolescents and adults ages 15 to 65. Younger and older people with increased risk should also be screened.[11]

Ask whether these tests already appear in your medical record. Many men assume a previous clinician performed them as part of routine blood work, although both require specific orders.

Sexually transmitted infection testing should reflect your sexual history, partners, symptoms, and exposure risks. A direct conversation gives your doctor more useful information than assumptions based on age or marital status.

10. Men Who Have Smoked Should Remember the Age-65 Ultrasound

The U.S. Preventive Services Task Force recommends one abdominal ultrasound for men ages 65 to 75 who have ever smoked. The test looks for an abdominal aortic aneurysm, an enlargement in the main artery running through the abdomen.[12]

In this recommendation, "ever smoked" commonly means at least 100 cigarettes over a lifetime.

Men ages 65 to 75 who have never smoked may still discuss selective screening. The decision can account for family history and other cardiovascular risks.

This screening occurs once, which makes it easy to overlook when no system tracks whether you completed it.

Tests That Should Not Become Automatic After 40

More testing can produce more abnormal results without improving your health.

A test may lead to repeat imaging, biopsy, anxiety, cost, or treatment of something that would never have caused harm. Before agreeing to a broad preventive panel, ask:

• What condition are we looking for?

• Do I have symptoms or risk factors for it?

• Does a medical guideline recommend this test for someone like me?

• What would an abnormal result lead to?

• Would a normal result change my care?

• Is the test covered by insurance?

• What are the risks of follow-up testing?

These questions are especially useful when considering whole-body scans, extensive hormone panels, tumor-marker tests, or repeated advanced cardiovascular imaging.

Preventive care should produce decisions. A long report without a clear follow-up plan has limited clinical value.

What a Thorough Visit After 40 Should Cover

Testing is only one part of preventive care. Your appointment should also address:

• Family history, including the age when relatives developed disease

• Tobacco, alcohol, and other substance use

• Exercise, strength, and cardiovascular fitness

• Nutrition and changes in weight

• Sleep quality and daytime alertness

• Sexual function and urinary symptoms

• Mood, stress, and depression

• Medication and supplement use

• Vaccination history

• Skin changes and sun exposure

• Dental, hearing, and vision care

• Your personal priorities for the next decade

A clinician needs enough time to connect those topics. For example, erectile dysfunction, a rising hemoglobin A1C, blood pressure readings near 145/90, and a 38-inch waist may form a cardiovascular and metabolic pattern that deserves a coordinated plan.

Concierge and direct primary care practices may provide longer appointments and easier follow-up. Membership alone does not guarantee appropriate screening or sound medical judgment. Ask how the physician approaches prevention, tracks screening deadlines, and follows abnormal results.

Frequently Asked Questions

What blood tests should a man over 40 get?

Common discussions include a cholesterol panel and blood glucose or hemoglobin A1C. Lipoprotein(a) should generally be measured at least once in adulthood. Other blood tests should reflect symptoms, medications, medical history, and risk.

Should every man over 40 have his testosterone checked?

No. Current Endocrine Society guidance recommends testing when symptoms and signs suggest testosterone deficiency. Diagnosis requires consistently low early-morning results on at least two tests.

At what age should men get a colonoscopy?

Average-risk colorectal cancer screening begins at 45, but colonoscopy is only one option. Stool-based testing and other screening methods are also available.

When should a man get a prostate-specific antigen test?

Current U.S. Preventive Services Task Force guidance recommends an individual decision for men ages 55 to 69. Family history and other risk factors may justify an earlier conversation.

Should every man over 40 get a coronary calcium scan?

No. A coronary calcium scan may help when cardiovascular risk remains uncertain and the result could change a treatment decision. Your doctor should first assess standard risk factors and explain how each possible result would affect care.

Does an annual physical include all of these tests?

Usually not. Services vary by practice, age, insurance coverage, symptoms, and personal risk. Ask your doctor which tests have been ordered and which screenings remain due.

The Bottom Line

Men's health after 40 requires more than ordering a large blood panel.

Start with accurate blood pressure, cholesterol and cardiovascular-risk assessment, blood-sugar screening when indicated, and colorectal cancer screening at 45. Add prostate, lung, testosterone, sleep, infection, and aneurysm testing when your age, symptoms, or risk factors support them.

The goal is a plan you and your doctor can follow over time.
