Preventive Health Risk Calculators & Screening Resource Directory
-
AHA PREVENT Cardiovascular Risk Calculator
Estimates the likelihood of developing cardiovascular disease, atherosclerotic cardiovascular disease and heart failure over 10 years, and over 30 years for eligible younger adults. It incorporates cardiovascular, kidney and metabolic health factors.
Intended users: Adults ages 30–79 without known cardiovascular disease, with clinician support.
Limitations: Not designed for people with established cardiovascular disease or certain other excluded conditions. Results require clinical interpretation. The AHA updated the calculator on October 14, 2026, to correct an issue with an optional HbA1c predictor.
-
Breast Cancer Risk Assessment Tool (BCRAT / Gail Model)
Estimates a woman's chance of developing invasive breast cancer over the next five years and through age 90, using age, reproductive history, breast biopsy history and breast cancer history in close relatives.
Intended users: Women for whom the model is applicable, generally without a prior breast cancer diagnosis or known high-risk genetic mutation.
-
BCSC Breast Cancer Risk Calculators
Offers validated tools estimating five-year invasive breast cancer risk and six-year advanced breast cancer risk in screening populations.
Intended users: Women undergoing mammography who want a more individualized risk discussion.
Limitations: The advanced cancer tool uses specific mammography screening assumptions. Risk estimates depend on accurate input data and are not a diagnosis or a replacement for screening recommendations. Use the current version of each calculator rather than archived versions.
-
Assesses inherited breast and ovarian cancer risk using family history, genetic test results when available, and other relevant factors.
Intended users: People with a significant family history of breast or ovarian cancer, known genetic variants, or possible hereditary cancer syndromes.
Limitations: Requires detailed and accurate family history and may require genetic information. Results should be interpreted with a qualified healthcare professional or genetic counselor. It does not replace genetic counseling or genetic testing.
-
Colorectal Cancer Screening Recommendations
Explains screening options for colorectal cancer, including stool-based tests and colonoscopy, and the ages and intervals at which screening is recommended.
Intended users: Average-risk, asymptomatic adults ages 45–75; screening from ages 76–85 is individualized.
Limitations: The average-risk recommendation does not apply to people with certain prior colorectal conditions, hereditary syndromes or other high-risk histories. Symptoms such as rectal bleeding require clinical evaluation rather than a routine screening calculator.
-
Lung Cancer Screening Eligibility
Helps determine whether someone meets U.S. preventive screening criteria for annual low-dose CT scans based on age and smoking history.
Intended users: Adults ages 50–80 with at least a 20 pack-year smoking history who currently smoke or quit within the past 15 years.
Limitations: Eligibility does not guarantee that screening is appropriate for every individual. A clinician should discuss benefits, false-positive findings, potential harms and whether the person could undergo treatment if cancer were detected.
-
CDC Chronic Kidney Disease Risk Calculators
Provides two calculators: one estimates the probability of having stage 3–5 chronic kidney disease (CKD), and the other estimates the likelihood of progression to kidney failure in people who already have CKD.
Intended users: Adults concerned about kidney disease and clinicians assessing kidney risk.
Information needed: Age, sex and medical history for the CKD calculator; kidney function and urine albumin results, with additional laboratory results for the more detailed progression model.
Limitations: The CDC identifies these as clinical and research tools. They should not be used to diagnose or manage kidney disease independently.
-
Kidney Failure Risk Equation (KFRE)
Estimates the probability of kidney failure requiring dialysis or transplantation over two or five years in people with established chronic kidney disease. The standard four-variable equation uses age, sex, estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (uACR).
Intended users: People with established CKD and clinicians managing kidney disease.
Limitations: Not intended to predict kidney disease in otherwise healthy people. The calculation requires reliable laboratory data and is most useful when incorporated into clinical assessment. The CDC kidney calculator above also offers a kidney failure progression model.
-
A brief questionnaire that helps adults assess their likelihood of having prediabetes or developing type 2 diabetes, based on common risk factors.
Intended users: Adults who want to understand their diabetes risk and whether to discuss blood glucose testing with a healthcare professional.
Limitations: It is a screening questionnaire, not a diagnostic test. A high score does not confirm prediabetes; a low score does not rule it out. Laboratory testing may be appropriate based on age, medical history and other risk factors.
-
American Diabetes Association Type 2 Diabetes Risk Test
Helps adults understand their risk of type 2 diabetes using factors such as age, weight, physical activity, family history and history of gestational diabetes.
Intended users: Adults who want to assess diabetes risk and determine whether further screening may be worthwhile.
Limitations: The result does not diagnose diabetes or prediabetes. A clinician may recommend HbA1c, fasting plasma glucose or another appropriate laboratory test.
-
FRAX Fracture Risk Assessment Tool
Estimates the 10-year probability of a hip fracture and a major osteoporotic fracture using clinical risk factors. Bone mineral density can also be entered when available.
Intended users: Adults being assessed for osteoporosis or fracture risk, particularly postmenopausal women and older adults.
Limitations: The calculator requires selection of the appropriate country model. It does not replace a DXA scan or a clinician's assessment, and it may underestimate risk in some circumstances, including certain recurrent-fall or fracture situations.
-
CDC Adult Immunization Schedule
Provides age-based vaccination recommendations for adults, with additional guidance for people with certain medical conditions, occupational exposures, travel needs and other risk factors.
Intended users: Adults and healthcare professionals reviewing immunization status.
Limitations: This is a clinical schedule, not an individualized calculator. Recommendations can change, and the appropriate vaccines depend on vaccination history, health conditions, contraindications and current guidance. Verify the current schedule before publishing or making recommendations.
How to use these resources
Choose a tool relevant to your health concerns or family history.
Review the information required before beginning.
Use the results as a starting point for discussion with your healthcare professional.
Keep track of recommended laboratory tests, screenings, vaccinations and follow up appointments.
Important: Online calculators and screening resources do not diagnose medical conditions and cannot replace individualized medical advice. A low risk estimate does not necessarily mean screening is unnecessary. Recommendations depend on your age, medical history, family history, previous results and individual circumstances.
