Health Screenings

Explore recommended health screenings for you. Each screening is explained in simple terms: who should get it, what to expect, and why it matters for your health.

11 categories
34 screenings

Cardiometabolic

Blood pressure, diabetes, and lipid screening

Blood pressure screening (hypertension)

A simple blood pressure reading helps detect hypertension, often before any symptoms appear.

Adults (routine care)At routine visits (often at least yearly; more often if elevated or on treatment)

Type 2 diabetes risk assessment questionnaire

A validated diabetes risk questionnaire, such as FINDRISC or CANRISK, can help decide whether blood-test screening is supported and how closely follow-up should happen.

Canadian adultsOptional risk assessment; timing depends on clinical context

Type 2 diabetes screening (A1C and/or fasting plasma glucose)

Blood tests like A1C and fasting plasma glucose can detect prediabetes and Type 2 diabetes early.

Adults age 40+ in Canada, or younger if risk factors are presentEvery 3 years from age 40 in Canada; earlier or more often if high risk

Dyslipidemia screening (lipid profile)

A lipid profile measures cholesterol and triglycerides to estimate cardiovascular risk.

Adults (risk-based)Commonly every 3–5 years in lower risk adults; more often if elevated or on treatment

Lifestyle

Brief screens that support lifestyle risk reduction

Tobacco use screening

A brief screen identifies tobacco/nicotine use and helps connect you to effective quitting support.

Teens and adultsAt routine visits (often yearly)

Unhealthy alcohol use screening (e.g., AUDIT-C)

AUDIT‑C is a 3‑question screen that helps identify unhealthy patterns of alcohol use.

AdultsPeriodically (often yearly or during checkups)

Substance use screening (non-alcohol)

A brief screen helps identify substance use risks and connect you to harm-reduction and treatment options.

Teens and adults (context-dependent)Periodically (often during routine visits)

Mental Health

Mental health screening questionnaires and supports

Depression screening (questionnaires)

A brief questionnaire can help identify depression so support and treatment can start earlier.

Adults (18+)Periodic (implementation varies)

Safety & Social

Safety and social screening used in primary care and OB settings

Intimate partner violence screening

A brief screen can help identify intimate partner violence and connect people to confidential support.

Women of reproductive age (varies by setting)Periodic (implementation varies)

Pediatrics

Screening and preventive checks in children

Vision screening in children (amblyopia risk detection)

Vision screening in preschoolers can detect amblyopia risk factors when treatment works best.

Children age 3-5At least once between ages 3 and 5

Cancer

Organized and clinical cancer screening and surveillance

Colorectal cancer screening (fecal immunochemical test - FIT)

FIT is a home stool test used in many Canadian provincial screening programs to detect signs of colorectal cancer early.

Varies by province (commonly 50–74)Varies by province (often every 2 years; Alberta uses yearly FIT)

Colorectal cancer screening/surveillance (colonoscopy)

Colonoscopy examines the colon and can remove polyps, which can prevent colorectal cancer.

Risk-basedRisk-based (set by your clinician/gastroenterologist)

Cervical cancer screening (Pap test / cervical cytology)

A Pap test checks cervical cells for changes that can be treated before they become cancer.

Varies by province (often starts 21–25 and ends 65–69)Often every 3 years when Pap is used (province-specific)

Cervical cancer screening (primary HPV test)

Primary HPV screening checks for high‑risk HPV types and can allow longer intervals when results are negative.

Varies by province (commonly 25–69)Often every 5 years when HPV-negative (province-specific)

Breast/chest cancer screening (screening mammography)

Screening mammography is an X‑ray test that can find breast cancer early, often before it can be felt.

Varies by province (e.g., ON/BC: 40–74; QC/MB: 50–74; AB: 45–74)Often every 2 years (some provinces recommend annual in ages 40–49)

Lung cancer screening (low-dose CT / LDCT)

Low-dose CT (LDCT) lung screening is intended for eligible high-risk people (program-defined) and is not recommended for average-risk individuals.

Varies by province (commonly 50–80)Typically yearly while eligible

Bone

Fracture risk assessment and bone density screening

Osteoporosis / fracture risk screening (FRAX/CAROC-style risk assessment)

FRAX/CAROC-style tools estimate your 10‑year fracture risk and help decide whether DXA testing or treatment is needed.

Usually 40+ (risk-based)Every few years, or after a major health change or fracture

Osteoporosis screening (bone mineral density test - DXA)

A DXA scan measures bone mineral density to diagnose osteoporosis and guide fracture prevention.

Risk-based (commonly older adults; earlier with risk factors)Every 2–5 years depending on results and risk (clinician-guided)

Vascular

Vascular screening such as AAA ultrasound

Abdominal aortic aneurysm screening (ultrasound)

An abdominal ultrasound can screen for an aortic aneurysm (AAA) before it becomes dangerous.

US: usually 65–75; Canada men: 65–80Usually one-time if normal; follow-up imaging if an aneurysm is found

Infectious Disease

Infection screening tests and panels

Chlamydia and gonorrhea screening (NAAT)

NAAT testing detects chlamydia and gonorrhea, common, often silent infections that are treatable.

Risk-based (often teens and young adults)Based on risk (often at least yearly when risk is ongoing; sooner after exposure)

HIV screening (serology)

HIV screening detects infection early. Treatment is highly effective and reduces transmission.

Adolescents and adultsAt least once; repeat based on risk (and during pregnancy)

Hepatitis C screening (serology)

Hepatitis C screening is a blood test that can identify infection; modern treatment is curative for most people.

AdultsOften one-time; repeat if ongoing risk

Hepatitis B screening (serology)

Hepatitis B screening checks for infection and immunity and helps guide vaccination and care.

Risk-basedBased on risk (and during pregnancy)

Syphilis screening (serology)

Syphilis screening is a blood test used in risk-based testing and routine prenatal care.

Risk-basedBased on risk (and during pregnancy)

Latent tuberculosis infection screening (LTBI)

LTBI screening tests for TB infection in people at higher risk, before symptoms appear.

Risk-basedBased on risk and exposure (repeat if ongoing risk)

Pregnancy

Pregnancy screening tests (prenatal care)

Prenatal aneuploidy screening (first trimester screen / NIPT where applicable)

Prenatal aneuploidy screening estimates the chance of certain chromosomal conditions. This is screening, not a diagnosis.

Pregnancy (timed testing, usually first trimester/early second)Once per pregnancy (timing depends on the test)

Gestational diabetes screening

Gestational diabetes screening checks how your body handles sugar during pregnancy and helps reduce complications.

Pregnancy (commonly 24–28 weeks)Once per pregnancy (sometimes earlier and/or repeated based on risk)

Group B strep screening in pregnancy

GBS screening helps determine whether antibiotics are recommended during labour to protect the newborn.

Pregnancy (late pregnancy)Once per pregnancy (late pregnancy)

Prenatal infectious disease screening (e.g., HIV, HBV, syphilis)

Prenatal infection screening uses blood tests to protect both parent and baby (commonly HIV, hepatitis B, syphilis).

PregnancyOnce per pregnancy (timing varies; sometimes repeated based on risk)

Asymptomatic bacteriuria screening during pregnancy (urine culture)

A urine culture early in pregnancy can detect silent bacteria that increase the risk of kidney infection and pregnancy complications.

Pregnancy (early pregnancy)Typically once early in pregnancy (practice varies)

Rh(D) incompatibility screening (blood typing and antibody testing)

Blood type and antibody screening identify pregnancies at risk of Rh(D) incompatibility so complications can be prevented.

PregnancyFirst prenatal visit; repeat antibody testing later in pregnancy if applicable

Newborn

Newborn screening programs (province-defined)

Newborn screening (metabolic/endocrine panels - province-defined)

A heel-prick blood spot test screens newborns for a province-defined set of rare but treatable conditions.

Newborn period (usually within the first 1–2 days of life)Once after birth (sometimes repeated in certain situations)

Newborn hearing screening

A quick, painless test checks a newborn’s hearing so support can start early if needed.

Newborn periodOnce after birth (repeat if the initial screen is inconclusive)

Newborn critical congenital heart disease screening (pulse oximetry)

Pulse oximetry screening measures oxygen levels to help detect some critical congenital heart defects before a newborn becomes ill.

Newborn periodOnce after birth (before discharge; timing varies by program)
