Common Cholesterol Test Kit Problems
Medical testing devices such as the increasingly common cholesterol test kit aimed at the domestic market depend on the reliability of the results they produce. Imagine the confusion and worse if devices such as thermometers for example couldn’t be relied on to give consistent and accurate readings. The same goes for all types of blood testing equipment.
However, no matter how well made consumer medical tests are these days they often don’t perform as well as they do in clinic test conditions and that’s almost always because of the people who use them. Hard to believe that someone would take a temperature reading just after either a very cold or hot drink – but they do and that the results are accordingly unpredictable is about the only predictable thing about them.
And so it is with cholesterol test kits – the majority of problems are not to do with the kit itself but rather lie with the person using it. In general it’s because of a straightforward failure to properly follow (or even read at all) the instructions. It’s amazing how many people are interested enough to want to know what their cholesterol levels are, yet don’t realise that eating or drinking anything twelve hours prior to the test will alter the levels quite significantly.
Contamination is another major culprit – simply not washing your hands can result in your blood sample containing traces of other substances that may very well affect the validity of the result. Another is inability to extract enough blood quickly enough to provide a fresh sample sufficient to fill the bowl (or similar receptacle).
Then of course there are tests that rely on light (reflective photometry to be technical) to analyze the results. Unfortunately, many people find it awkward to make out the result and so take the device over to (you guessed it) a bright light which effectively over exposes it.
Finally, never depend on the results of a single test. Even when conducted in a clinical setting it is not uncommon to notice differences between tests on the same individual. Like most else in your body, cholesterol levels fluctuate naturally so the only reliable guide is to take the average.Common Cholesterol Test Kit Problems,
