Is There A Faster Cheaper and Painless Way To Test Diabetes?

Diabetes, if not managed or treated with care, could easily lead to serious medical conditions including blindness, heart disease, high blood pressure, kidney disease, nervous system disease, stroke and amputation.

In order to diagnose whether a person is having diabetes or pre-diabetes, doctors usually use a fasting plasma glucose (FPG) test to measure blood glucose in that person who has not eaten anything for at least 8 hours. Sometimes, an oral glucose tolerance test (OGTT), which measures blood glucose after the person fasts at least 8 hours and 2 hours after the person drinks a glucose-containing beverage, might also be employed.

For diagnosis of diabetes (not for pre-diabetes), a random plasma glucose test is used. The test, also known as casual plasma glucose test, measures blood glucose of a person at any time without regarding when this person last ate.

Here comes the so-called Wrinkle Test, which is considered as a faster and cheaper method to diagnose if a person has diabetes. The Wrinkle Test can identify a disorder in the sensors on a person’s skin and was developed by researchers at the National University of Singapore (NUS) and the National University Hospital (NUH).

Carrying out the test is fairly simple. Apply a local anesthetic as cream on the fingers of the person being tested. If the skin does not wrinkle after some time, then this person must has a nerve fiber disorder that could be caused by disease like diabetes.

The results of the test are compared against a scale of between zero and 4. Zero indicates there is no wrinkling and is a sign that the constriction of blood vessels is being impaired. Studies have shown that wrinkling is caused by a constriction of blood vessels. A patient with a small nerve fiber disorder, which disrupts the constriction, would have fewer wrinkles.

Though many diseases could actually cause a disorder on the small nerve fibers on the patients’ skin, diabetes is the most important cause because almost half of the diabetic patients in Singapore suffer from some kind of the disorder.

Nevertheless, Wrinkle test is surely not the only way to identify nerve fiber disorders. In fact, nerve disorder could be diagnosed by removing a skin sample, which was then sent to laboratory for testing. And it usually takes between 1 to 2 weeks before results can be known.

  1. This is a very useful and essential test for the diabetic,it is very essential that the disease is in check.
