The Global Impact of Diabetes
Diabetes is a chronic disease that occurs when the human body cannot effectively produce or regulate insulin, a hormone critical to the regulation of blood sugar (glucose). From 1990 to 2022, the number of people living with diabetes rose from 200 million to 830 million. In 2022, 14% of people 18 years or older were living with diabetes. This is a 7% increase from 1990. More than half of adults over 30 years old who were living with diabetes were not taking medication to manage their diabetes. In 2021, diabetes was the direct cause of 1.6 million deaths. Complications from diabetes can include blindness, kidney failure, heart attacks, stroke, and lower limb amputation. A healthy diet, regular physical activity, avoiding tobacco, and maintaining a body weight that is healthy for your age and gender can help prevent or delay the onset of severe diabetes symptoms or complications. Utilizing diagnostics to detect and monitor diabetes is beneficial for both clinicians and patients in helping to maintain a treatment plan or lifestyle that is meant to increase positive outcomes for patients living with diabetes (1).
The Evolution of Diabetes Testing: From Tasting Urine to Modern Diagnostics
The idea of diagnosing someone with diabetes by actually tasting their urine seems unimaginable to most of us today. Nevertheless, our current understanding of diabetes testing has evolved along fascinating pathways of history and medical genius.
In the Beginning: Diagnosing Diabetes by Taste
Diabetes has been known as a disease since ancient times. Evidence from around 1500 B.C. indicates some knowledge of symptoms of diabetes. By 600 B.C., physicians made the amazing observation that ants were attracted to the sweet urine of those afflicted with diabetes, which led to the first known association between sugar in urine and diabetes.
During the Middle Ages, a practice known as uroscopy emerged among practitioners. Here, urine was examined to diagnose a number of ailments. The sugar in urine had a special, sweet taste, which was a hallmark of this diagnosis. The physicians of that time used detailed charts cataloguing the flavor of urine based upon the urine's appearance, smell, and taste to formulate their assessment.
In 1674, English physician Thomas Willis awesomely described diabetic urine as "wonderfully sweet as if it were imbued with honey or sugar." The first clinical test for the detection of sugar in urine was created in 1841 by German chemist Karl Trommer, who applied acid hydrolysis to analyzing urine samples for predicting sugar content levels.
Shifting Towards Detection and Treatment in the 20th Century
With the beginning of more accurate detection by modern standards and treatment of diabetes in the 20th century, these early techniques gave way to the most radical organizational shift. Injecting into the paradigm of consideration was the discovery and use of insulin surgical events, which altered the treatment of diabetes.
The introduction of the Oral Glucose Tolerance Test (OGTT) in 1922 provided a more accurate means for the diagnosis of diabetes by observing the response of the body to glucose load. It heralded a new age in diabetes care.
Urine test strips, which were introduced in the 1950s for simplicity in monitoring blood glucose levels, were refined in 1964 by The Ames Company (a division of Miles Laboratories, subsequently acquired by Bayer) to the point of widespread accessibility. Finally, the first "portable" glucose monitor came into being in 1970. Nevertheless, it was only during the 1980s that easy-to-use home glucose monitors became available for those with diabetes, allowing for regular blood sugar level checks.
While glucose monitors and test strips transformed diabetes management on a daily basis, they had one disadvantage: they were capable of showing blood glucose levels at a single point in time without taking into account the fluctuations that occurred over hours or days.
The A1C Testing Era Emerges
To get around this limitation, the 1970s saw the birth of A1c testing, a landmark advance from which diabetes care would never be the same again. Rather than a measure of blood glucose concentration at a single point in time, A1c measures long-term blood glucose control with average blood sugar levels over a window of the past two to three months. This has made it an important tool for diagnosing diabetes and, more importantly, in assessing how patients are managing their diabetes.
The A1c test continues to be used widely in both clinical and research settings as a method for gauging diabetes control. It is accepted as a reliable means to assess long-term status of blood glucose and therefore gives doctors important information to aid them in assessing the efficacy of treatment strategies.
Understanding the A1c Measurements
Though blood glucose tests can confirm the presence of diabetes, the A1c test provides a more complete view of long-term glucose control. There are fuzziness on the exact limit met from the normal A1c to the range suggesting diabetes. The International Expert Committee recommended a cut-off for diagnosing diabetes that favours specificity.
The appeal of capillary blood A1c measurement, otherwise known as POC A1c testing, is growingly appreciated in clinical settings as a convenient and useful tool for in-office glucose control monitoring. While some promising results have been produced with respect to newer POC instruments, there remains a need for greater studies to establish their reliability among diverse populations.
What Does the Future Hold for Diabetes Testing?
Advances in diagnostic technologies will further ameliorate the tools for managing and diagnosing diabetes. From urine tasting to hemoglobin A1c testing, the journey of diabetes testing reflects medical civilization and the commitment for better, more accessible health for all. Brands like SEKISUI Diagnostics stand committed to the evolving, sharpening of diagnostic tools that will help diabetics gain better management of their lives. (2)
