Why age-based screenings matter
Preventive screenings are tests ordered for people who have no symptoms. Their purpose is to detect conditions early, when treatment is more effective and less expensive. The U.S. Preventive Services Task Force (USPSTF) issues evidence-based recommendations that specify which screenings to offer, at what age, and how often. Many of these screenings are covered at no cost-sharing under the Affordable Care Act when billed as preventive care. For a plain-language explanation of what that coverage typically includes, see what preventive care actually covers.
This article is general health information, not medical advice. Your clinician will consider your personal history, family background, and risk factors when recommending specific tests. Always consult a qualified healthcare professional before making decisions about your own care.

Screenings for children and adolescents (birth through age 17)
Well-child visits follow a dense schedule in the first two years of life, then shift to annual checkups. At each visit, the clinician tracks growth, development, and immunization status. Common screenings across this age range include:
- Newborn metabolic and hearing screening (first days of life)
- Vision and hearing checks at ages 3 to 5, then periodically through adolescence
- Blood pressure measurement starting at age 3
- Lead exposure screening for children at elevated risk (typically ages 1 to 2)
- Autism spectrum disorder developmental surveillance through age 3, with formal screening at 18 and 24 months
- Depression screening for adolescents aged 12 and older
- Obesity screening with body mass index (BMI) assessment starting at age 6
For a detailed breakdown organized by specific age milestones, pediatric preventive care checkups covers each well-child visit and what to expect.
Screenings for adults aged 18 to 64
Adult screening schedules are shaped by age, sex, and risk factors. The intervals below reflect general USPSTF guidance; a clinician may adjust frequency based on individual circumstances.
| Screening | Who | General frequency |
|---|---|---|
| Blood pressure | All adults | At least every 2 years if normal; annually if elevated |
| Cholesterol (lipid panel) | Adults with cardiovascular risk factors | Varies by risk level |
| Diabetes (blood glucose) | Adults aged 35 to 70 who are overweight or obese | Every 3 years if normal |
| Cervical cancer (Pap smear / HPV test) | People with a cervix, ages 21 to 65 | Every 3 to 5 years depending on test type |
| Colorectal cancer | Adults aged 45 to 75 | Varies by test type (colonoscopy every 10 years; stool tests annually) |
| Breast cancer (mammography) | Women aged 40 to 74 | Biennial; some guidelines support starting at 40 |
| Depression | All adults | Periodically |
| Lung cancer (low-dose CT) | Adults aged 50 to 80 with a significant smoking history | Annually |
STI screenings, including those for HIV, gonorrhea, chlamydia, hepatitis B, and hepatitis C, have their own age and risk-based recommendations. HIV screening, for example, is recommended at least once for all adults aged 15 to 65, with more frequent testing for higher-risk individuals.
Screenings for adults 65 and older
Older adults carry a higher baseline risk for several conditions, and some screenings are introduced or intensified after age 65. Others are discontinued when the harms of screening begin to outweigh the likely benefits, a determination that should be made in conversation with a clinician.
- Osteoporosis: Bone density testing (DEXA scan) recommended for women aged 65 and older, and for younger postmenopausal women with elevated fracture risk.
- Abdominal aortic aneurysm: One-time ultrasound for men aged 65 to 75 who have ever smoked.
- Cognitive assessment: No formal USPSTF recommendation for routine screening exists, but clinicians often assess cognition at annual wellness visits.
- Vision and hearing: Annual checks support fall prevention and quality of life.
People managing chronic conditions such as hypertension, diabetes, or heart disease will likely follow additional monitoring schedules set by their care team. For special populations including pregnant individuals and those with serious chronic illness, recommendations differ significantly, so direct consultation with a healthcare provider is necessary.
Keeping organized records of past screenings helps both patients and clinicians avoid duplicate testing and identify gaps. Family health records explains what to document and how to store it.
Putting screenings into your family's routine
Fitting preventive appointments into a busy household takes planning. The USPSTF and CDC both maintain online tools that can help families identify which screenings apply to each member by age and sex. An annual preventive health checklist can serve as a practical starting point for organizing the year. For longer-term scheduling across a household, building a preventive care routine offers step-by-step strategies.
Understanding the cost side of preventive care is also worth attention. Many screenings fall under the no-cost preventive benefit in qualifying health plans, but billing errors and out-of-network providers can result in unexpected charges. Reviewing your plan's specific coverage before each appointment reduces surprises. General guidance on managing those costs is available in the Managing Health Costs section of this site.
