Screening discussion

Overall comparison

Discuss individualized screening

The profile fits a selective or reasonable screening pathway rather than a universal recommendation.

USPSTF 2019

Selectively offer screening · Grade C

For men aged 65–75 who never smoked, USPSTF recommends selective screening after considering family history and other risk factors.

ACC/AHA 2022

No automatic ACC/AHA screening indication

The entered factors do not match a specific ACC/AHA recommendation; clinical context may still change the decision.

SVS guidance

No automatic SVS screening indication

The entered factors do not match a specific SVS screening recommendation.

Optional record context

Bloodwork—not an AAA screening test

There is no separate male or female blood panel that determines AAA screening. Sex at birth changes the evidence branch above; laboratory testing is selected from the person’s broader cardiovascular, metabolic, and kidney history.

Core context

Lipid profile, glycemic testing, and kidney function may support broader cardiovascular care when clinically appropriate.

Sex-specific care

Reference intervals and preventive testing can differ by sex, age, medications, pregnancy history, and laboratory method; this page does not label results normal or abnormal.

D-dimer boundary

D-dimer is nonspecific, is not included in the USPSTF, ACC/AHA, or SVS AAA screening criteria, and does not replace ultrasound. Enter it only to carry an already-ordered result into the printed discussion summary.

How to use the result

What happens next?

Confirm the history

Verify age, smoking exposure, first-degree family history, symptoms, and whether a prior ultrasound already occurred.

Discuss ultrasound

AAA screening is a one-time abdominal ultrasound—not a CT scan or blood test—for most eligible asymptomatic adults.

Keep labs separate

Review cardiovascular and kidney labs for their own indications without using them as an AAA screening score.
