What is medical testing?
You've probably had a blood or urine test at some point. Doctors use medical tests like these to learn more about your health. The results can reassure you that all's well or identify problems that require treatment.
Checklist of vital health tests
As you get older, it's advisable to consider having regular tests for:
- cholesterol levels
- blood pressure
- susceptibility to diabetes
Where you can have tests done
You'll usually be tested at your doctor's surgery. From there, your doctor might refer you to a specialist. Sometimes you can do home testing.
Testing for cholesterol
You're most at risk of high cholesterol if you're a man over 45 or a woman over 55.
High cholesterol is a major risk factor for heart disease, especially if you have high blood pressure or smoke, eat a high fat diet or are physically inactive.
The test for high levels of cholesterol is a simple blood test, drawn from a vein in your arm or finger.
Your cholesterol levels change with time. So it's advisable to have at least two different tests several weeks or months apart before beginning any kind of treatment.
Testing your blood pressure
Your blood pressure tends to rise with age. If you have high blood pressure, also known as hypertension, you are more at risk of a stroke, heart disease or kidney failure.
Blood pressure needs to be checked regularly. It also has to be re-checked at different times to get an accurate reading.
Testing for diabetes
Up to one million people may have diabetes without knowing it, and many don't find out until their 50s. It is a serious health condition that's much more common with age.
Testing involves taking a sample of your urine to see if it contains glucose. You may have to have a blood test to confirm any diagnosis.
Having diabetes puts you at greater risk of strokes, heart disease, nerve, eye and kidney problems, yet in most cases diabetes can be avoided. Testing for it is a first step.
Diabetes testing is advisable once you're over 40, especially if you're overweight, Asian or have a family history of the disease.
You can have good sight into your 80s and 90s if you look after your eyes. You are entitled to a free sight test if you are over 60.
If you're over 50, you can have a free sight test if you:
- need complex lenses
- are registered blind or partially sighted
- have diabetes
- have, or are at risk of, glaucoma
An eye test is not just a test for glasses. It's important for your general health and to spot diseases of the eye that are more common as you age, like macular degeneration, cataracts and glaucoma.
Detecting hearing loss
Everyone loses some hearing ability with age. Age-related hearing loss, or presbyacusis, affects more than half of all people over 60. It's the second most common cause of disability as you age.
If you are worried about hearing loss, your doctor can examine your ears and do some simple tests, like asking what sounds you can hear. You'll also need to explain why you think your hearing is not as good as it used to be.
If your doctor thinks you might have hearing loss, you may be referred to an audiology clinic or Ear, Nose and Throat (ENT) department for further tests.
