DIY health testing is a booming industry worth £99 million a year in the UK - a rise of 30 per cent in the last five years and experts predict that figure will continue to rise. Increasingly people are taking their health into their own hands. There's no shortage of tests you can buy - everything from cholesterol to Chlamydia to diabetes. But can a test that costs as little as a few pounds from your local chemist really compare to the laboratory tests that your doctor would do? In this programme, Ginny Buckley puts the DIY tests to the test. She meets up with a group of consumers who have agreed to try out a range DIY kits which will measure their cholesterol levels, their liver function and look at their blood sugar to see if they're at risk of diabetes.
