Preventive health screenings help identify certain diseases and risk factors before they cause noticeable symptoms.
There is not one universal list of tests that every adult should complete every year. The screenings appropriate for you depend on your age, sex and anatomy, medical history, family history, lifestyle, previous results, medications, and individual risk factors.
Common preventive screenings may include blood pressure measurement, cholesterol testing, diabetes screening, cancer screening, bone-density testing, infectious-disease screening, and selected evaluations based on individual risk.
A thoughtful preventive health evaluation is therefore less about ordering every available test and more about determining which screenings are likely to provide useful information for you.
What Is a Preventive Health Screening?
A preventive health screening is a test or evaluation performed primarily to look for a health problem before symptoms have developed.
For example, someone may feel completely healthy while having:
High blood pressure
Elevated cholesterol
Prediabetes
Osteoporosis
Hepatitis C
Early-stage cancer
Screening may help identify some of these conditions earlier, when additional evaluation, monitoring, lifestyle changes, or treatment may be beneficial.
This is different from diagnostic testing. If you already have symptoms, testing is generally being performed to determine what is causing those symptoms rather than simply screening for an asymptomatic condition.

What Health Screenings Do Most Adults Need?
There is no single preventive screening schedule that applies to everyone, but several areas deserve consideration throughout adulthood.
Blood Pressure Screening
Blood pressure is one of the most basic and important preventive measurements.
The U.S. Preventive Services Task Force recommends screening adults 18 years and older for hypertension. Adults age 40 and older and adults at increased risk are generally screened more frequently, while younger adults with consistently normal blood pressure and low risk may be screened less often.
High blood pressure often causes no obvious symptoms, yet over time it can increase the risk of:
Heart disease
Stroke
Kidney disease
Heart failure
Other cardiovascular complications
An abnormal office reading may need to be confirmed with home or ambulatory blood-pressure measurements before hypertension is diagnosed.
Cholesterol and Lipid Screening
Cholesterol testing can help assess cardiovascular risk.
A lipid panel commonly evaluates:
Total cholesterol
LDL cholesterol
HDL cholesterol
Triglycerides
The CDC notes that most healthy adults should generally have cholesterol checked approximately every 4 to 6 years, although testing may be needed more frequently when cardiovascular risk is higher.
Factors that may influence testing frequency include:
Previous abnormal cholesterol
Diabetes
High blood pressure
Smoking
Kidney disease
Cardiovascular disease
Family history of premature cardiovascular disease
Family history of very high cholesterol
Laboratory testing should be interpreted in the context of your overall health rather than treating an individual number in isolation. You can learn more in our guide to Understanding Laboratory Testing.
Diabetes and Prediabetes Screening
Type 2 diabetes frequently develops gradually, and blood sugar may become abnormal long before noticeable symptoms occur.
The USPSTF recommends screening adults ages 35 to 70 who have overweight or obesity for prediabetes and type 2 diabetes. Screening may also be appropriate outside this group when additional risk factors are present.
Common screening tests include:
Fasting glucose
Hemoglobin A1c
Oral glucose tolerance testing in selected situations
Risk factors such as family history, previous gestational diabetes, metabolic abnormalities, medications, or other medical conditions may influence when testing should begin.
What Cancer Screenings Do Adults Need?
Cancer screening recommendations vary considerably depending on age, sex, anatomy, family history, previous findings, and cancer risk.
Several common examples include the following.
Colorectal Cancer Screening
For adults at average risk, the USPSTF recommends colorectal cancer screening beginning at age 45 and continuing through age 75.
Between ages 76 and 85, the decision is individualized according to health status, previous screening history, and other factors.
Screening options may include:
Colonoscopy
Fecal immunochemical testing (FIT)
Stool DNA testing
CT colonography
Other recommended screening strategies
A history of colon polyps, inflammatory bowel disease, certain genetic conditions, or a significant family history may require earlier or more intensive screening.
Breast Cancer Screening
For women at average risk, the USPSTF currently recommends screening mammography every two years from ages 40 through 74.
Women with increased risk because of genetic findings, family history, previous breast findings, or other factors may require a different screening strategy.
Additional imaging such as breast MRI may sometimes be appropriate for individuals at substantially increased risk.
Cervical Cancer Screening
Cervical cancer screening recommendations depend on age and the testing method used.
Under current final USPSTF guidance:
Women ages 21–29 are generally screened with cervical cytology, commonly called a Pap test, every three years.
Women ages 30–65 may use cervical cytology every three years, high-risk HPV testing every five years, or HPV/Pap cotesting every five years.
Routine screening can often stop after age 65 when adequate previous screening has been completed and there are no high-risk circumstances.
Previous abnormal Pap tests, cervical precancer, cervical cancer, immune-system conditions, or other risk factors can change this schedule.
Lung Cancer Screening
Lung cancer screening is not recommended for every adult.
The USPSTF recommends annual low-dose CT lung screening for adults ages 50 to 80 who:
Have at least a 20 pack-year smoking history, and
Currently smoke or quit within the previous 15 years.
Screening generally stops after someone has not smoked for 15 years or when health circumstances substantially reduce the expected benefit of screening.
A standard chest X-ray is not a substitute for recommended low-dose CT lung cancer screening.
Prostate Cancer Screening
Prostate cancer screening requires more individualized decision-making.
Current USPSTF guidance recommends that men ages 55 to 69 make an individual decision about PSA-based screening after discussing potential benefits and harms with their physician.
The USPSTF recommends against routine PSA-based screening in men age 70 and older.
Other professional organizations have somewhat different recommendations, and factors such as family history and individual prostate-cancer risk may affect the discussion.
Who Needs Bone-Density Screening?
Bone-density testing can identify osteoporosis before a fracture occurs.
The USPSTF recommends osteoporosis screening for:
Women 65 years and older
Postmenopausal women younger than 65 who are determined to be at increased fracture risk
A DXA scan is commonly used to measure bone mineral density.
Risk factors that may lead to earlier evaluation include low body weight, smoking, family history of hip fracture, certain medications, early menopause, and medical conditions that affect bone health.
For men, the USPSTF currently considers the evidence insufficient to recommend universal population screening, so bone-density testing is generally individualized.
Do Adults Need Screening for Hepatitis or HIV?
Certain infectious diseases can remain asymptomatic for years.
Hepatitis C
The USPSTF recommends hepatitis C screening for adults ages 18 to 79.
Additional or repeat testing may be appropriate for people with ongoing exposure risks.
HIV
The USPSTF recommends HIV screening for adolescents and adults ages 15 to 65, with screening outside that age range when increased risk is present.
Testing for other sexually transmitted infections may also be recommended depending on sexual history, pregnancy, exposure risk, and other individual circumstances.
Are There Other Preventive Screenings Some Adults Need?
Yes. Certain screenings are recommended only for specific populations or risk profiles.
One example is abdominal aortic aneurysm screening.
The USPSTF recommends a one-time abdominal ultrasound for men ages 65 to 75 who have ever smoked. Screening may be selectively considered in men within this age range who have never smoked.
Preventive evaluations may also include assessment of:
Depression and mental health
Tobacco use
Alcohol and substance use
Fall risk in older adults
Sexual health
Pregnancy-related risks when applicable
Vision and hearing concerns
Medication safety
Nutrition and physical activity
Weight and metabolic health
These may not always involve a laboratory test or imaging study, but they remain important components of preventive care.
Does Everyone Need the Same Screening Tests Every Year?
No.
This is one of the most important principles of preventive medicine.
A healthy 25-year-old with no significant family history should not automatically receive the same testing as a 62-year-old with a history of smoking, diabetes, hypertension, and a strong family history of colorectal cancer.
Screening decisions may depend on:
Age
Sex and relevant anatomy
Medical history
Family history
Previous screening results
Tobacco exposure
Cardiovascular risk
Metabolic risk
Medications
Pregnancy history
Occupational exposures
Sexual history
Other individual risk factors
More testing is not automatically better preventive care.
Tests can produce false-positive results, incidental findings, unnecessary follow-up procedures, anxiety, cost, and occasionally physical harm. The goal is to choose screening that has a reasonable likelihood of improving healthcare decisions.
Can Family History Change When Screening Should Begin?
Absolutely.
Family history can sometimes justify beginning screening earlier or using a different screening strategy.
Important examples include relatives with:
Colorectal cancer or advanced colon polyps
Breast cancer
Ovarian cancer
Prostate cancer
Pancreatic cancer
Premature heart disease
Severe cholesterol abnormalities
Osteoporosis or hip fracture
Known hereditary cancer syndromes
Other inherited medical disorders
The age at which your relative developed the condition can also be important.
Before your next preventive visit, consider updating your family medical history. Our guide to Preparing for Your Annual Preventive Health Evaluation explains what information can be helpful to gather in advance.
Do I Still Need Preventive Screening If I Feel Healthy?
Yes, when you meet appropriate screening criteria.
The purpose of screening is specifically to evaluate people who may not yet have symptoms.
Conditions such as hypertension, high cholesterol, prediabetes, osteoporosis, and several cancers may develop silently.
Feeling well is therefore not necessarily evidence that preventive screening is unnecessary.
At the same time, preventive healthcare should extend beyond simply ordering tests. Lifestyle, family history, physical activity, nutrition, sleep, tobacco exposure, medications, weight, cardiovascular risk, and personal health goals all contribute to the bigger picture.
Our Patient's Guide to Preventive Healthcare and Health Optimization explains how these pieces can be combined into a more individualized health strategy.
How Do I Know Which Preventive Screenings I Am Due For?
A good starting point is to review your screening history during a periodic preventive health evaluation.
Bring or review:
Your age
Current medications and supplements
Major medical conditions
Family medical history
Previous laboratory results
Date of your last mammogram, Pap/HPV test, colonoscopy, or other cancer screening when applicable
Smoking history
Previous bone-density testing
Vaccination history
Any new diagnoses in close relatives
Your physician can then compare this information with current evidence-based recommendations and determine which screenings are appropriate now, which can wait, and which may not be necessary.
At Ask Dr. Hu, our approach to Preventive Care & Health Optimization focuses on building an individualized plan rather than applying the same checklist to every patient.
The Bottom Line
Most adults need preventive health screening, but not every adult needs the same tests or the same testing frequency.
Common preventive screening discussions may include:
Blood pressure
Cholesterol and cardiovascular risk
Diabetes and prediabetes
Colorectal cancer
Breast cancer
Cervical cancer
Lung cancer for qualifying individuals
Prostate cancer when appropriate
Osteoporosis
Hepatitis C
HIV and other infections when appropriate
Selected additional screenings based on individual risk
The most useful approach is to develop a screening schedule based on your age, health history, family history, previous results, lifestyle, and personal risk factors.
Preventive healthcare works best when screening is combined with healthy lifestyle choices, appropriate follow-up, and an ongoing understanding of how your health changes over time.
