Which blood, heart and cancer screening tests should be done after 40, and who should be checked more often?
Forty is a turning point in health monitoring. The risk of high blood pressure, cholesterol, diabetes and some cancers begins to rise from this age, and most of these conditions progress silently for years. A regular check-up is the most effective way to catch disease before symptoms appear.
Core laboratory tests and measurements
Every check-up after 40 should include a full blood count, fasting glucose (and HbA1c where needed), total cholesterol, LDL, HDL and triglycerides, kidney and liver function tests, thyroid-stimulating hormone (TSH), urinalysis and a blood pressure reading. Vitamin D and B12 deficiency are also common at this age.
Heart assessment
A resting ECG is a suitable start for everyone. Stress ECG and echocardiography are added for people with early heart disease in the family, smokers, and those with diabetes or high blood pressure. A coronary calcium score can be informative for people at intermediate risk.
Screening by sex and age
- Women: From 40, mammography for breast screening (every two years in the national programme) and a smear or HPV test every five years between ages 30 and 65.
- Men: After 50, or earlier with a family history of prostate cancer, PSA and a urology consultation are decided together with your doctor.
- Everyone: From 50, a faecal occult blood test or colonoscopy for colorectal cancer screening. People with diabetes should have an eye-fundus examination every year.
How often?
For people with no known disease and low risk, a comprehensive assessment every one to two years is enough. People with high blood pressure, diabetes, high cholesterol or heart disease should be seen at the intervals set by their doctors, often every six months.
Preparing for a check-up
Fast for 8-12 hours before blood tests; you may drink water. Take regular medicines as your doctor instructs. Bring previous test results and a list of your medicines. This article is general information; the screening plan that suits you should be set with your doctor according to your age, family history and current complaints.
After the check-up: how to assess the report
Not every value outside the reference range means disease; results must be interpreted by age, sex and the medicines you take. Always review your report with a doctor and plan a repeat test or further investigation for abnormal values. Keep your results in a folder or your patient portal and follow the change over the years; the trend matters more than a single value.
The real benefit of a check-up is changing your lifestyle when findings appear and, if needed, starting early treatment. Losing weight, cutting salt, walking regularly and quitting smoking can reduce many risks without medication.
