Managing diabetes complications with Randox Reagents
The prevalence of diabetes is steadily increasing across the world, with approximately 422million people worldwide with diabetes and is currently one of the leading causes of death in the world. A diabetes diagnosis comes in three forms; Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus and Gestational Diabetes. Each type of diabetes can have long-term, detrimental effects to your health if it is not controlled, with some of the key complications being heart disease, kidney damage, retinopathy and even limb amputations.
Diabetes can be controlled through maintaining a healthy diet and regular exercise, however in situations where complications occur, innovative testing can aid in the prevention and management of detrimental consequences to patients. Randox Reagents offer a range of high performance and unique tests which can be used to manage complications of diabetes such as:
Kidney disease is a life threatening complication of diabetes, commonly called diabetic nephropathy in patients with diabetes. Around 40% of people with diabetes develop diabetic nephropathy, characterised through prolonged periods of high glucose levels in the blood. To effectively monitor diabetic nephropathy, it is essential to test cystatin C levels in patients, which is a useful indicator of renal function in patients where creatinine measurements are unreliable. Unlike creatinine, cystatin C does not have a ‘blind area’ – up to 50% of renal function can be lost before significant creatinine elevation occurs. This makes cystatin C capable of detecting early stage kidney dysfunction in patients with diabetic nephropathy.
Microalbumin testing is also important to identify patients with diabetic nephropathy approximately 5-10 years earlier than proteinuria tests, helping to reduce the incidence of end stage renal disease. This is because low albumin concentrations in the urine are the earliest market of renal damage and therefore enable preventative measures to be taken.
Metabolic syndrome is a severe complications of uncontrolled diabetes which contains a number of conditions which occur together, increasing your risk of heart disease, stroke and diabetes. Metabolic syndrome can be monitored through measuring Non-Esterified Fatty Acids (NEFA), which are molecules released from triglycerides by the action of the enzyme lipase and are transported in the blood bound to albumin. NEFA contributes a small proportion of the body’s fat, however they provide a large part of its energy, with elevated concentrations having adverse effects on both carbohydrate and lipid metabolism.
With the global burden of diabetes rising year on year, diabetes complications monitoring has never been more important. Randox Reagents offer a wide range of innovative testing to laboratories, to help clinicians accurately diagnose and monitor diabetes complications.

On 9 March 2017, Randox Reagents are celebrating World Kidney Day! World Kidney Day is a global campaign aimed at raising awareness of the importance of our kidneys to our overall health. It aims to reduce the frequency and impact of kidney disease and its associated health problems worldwide.
This year, the World Kidney Day promotes education on the harmful consequences of obesity and its association with kidney disease, advocating healthy lifestyle and health policy measures that make preventive behaviours an affordable option.
With this in mind, throughout the week we have been sharing on social media some interesting facts on diagnostic tests which can help aid an early risk assessment of kidney disease in obese patients, allowing preventative action to be taken before any serious damage occurs. The tests of focus this week included cystatin C, adiponectin and microalbumin…
The creatinine test is routinely run for patients who are suspected for deteriorating kidney function, however this test has limitations. Cystatin C is an alternative test, and is particularly useful in patients where creatinine measurements are not suitable e.g. individuals who are obese, malnourished, have liver cirrhosis or reduced muscle mass. Importantly, unlike creatinine, cystatin C does not have a ‘blind area’ – up to 50% of kidney function can be lost before significant creatinine elevation occurs. Cystatin C is extremely sensitive to very small changes in kidney function and is therefore capable of detecting early stage kidney dysfunction. The cystatin C test therefore allows preventative measures to be taken much earlier and before significant kidney function decline.
There is substantial evidence that excess visceral fat is the main driving force for almost all of the disorders associated with the metabolic syndrome, including CKD.1,2 The adiponectin test from Randox can accurately assess levels of abdominal visceral fat, independent of age, race or fitness level.3,4 Assessing adiponectin, and therefore visceral fat levels, can help assess risk of CKD, as well as a range of other illnesses such as pre-diabetes, CVD and various cancers.
The microalbumin test detects very low levels of a blood protein called albumin, in urine. The detection of albumin in urine can be an indicator of kidney injury and can result in irreversible damage if left untreated. Low albumin concentrations in the urine are the earliest marker of kidney damage and therefore enable preventative measures to be taken. Microalbumin testing can identify individuals with diabetic nephropathy approximately 5-10 years earlier than proteinuria tests helping reduce the frequency of end stage renal disease.
Both World Kidney Day and Randox are working towards improving healthcare worldwide. With continuous investment in R&D, Randox are helping with the risk assessment and earliest detection of renal function problems. By assessing one’s risk of kidney problems (with the adiponectin test), it can give patients (obese and other) the tools to prevent kidney problems further on down the line. With early diagnosis (through the cystatin C and microalbumin tests) it will be possible to keep kidney problems from getting worse, therefore lowering the number of those diagnosed with CKD worldwide.
A laboratory running a competitors 3rd party Microalbumin QC noticed shifts in their QC values whenever they changed reagent batch.
They tested two levels of quality control over three different batches of reagent the results can be seen in the table below.
|Competitor Control – Microalbumin|
As can be seen from the findings above, Microalbumin results shifted significantly each time they changed reagent batch. This was the case for both the level one and level two control however when the lab tested the same set of patient samples across the three reagent batches results were consistent and did not show the same shifts.
The laboratory decided to contact Randox and ask about our Microalbumin controls. They were concerned about the shifts seen with their current supplier and highlighted the fact they were no longer confident in the results they were releasing. This led to them trialling the Randox liquid ready-to-use Microalbumin control with the same three reagent batches they tested previously.
Having tested two levels of the Randox quality control over the same three reagent batches the laboratory reported to us that their results were back on track and they were delighted with the outcome! The results of the Randox control can be seen in the table below.
|Randox Control – Microalbumin|
The difference seen with the Randox control across the three reagent batches was much smaller than that of their previous control and was in line with the changes seen with their patient samples.
This case study highlights the commutability of the Randox QC range. By using a control with a matrix that reacts to the test system in the same manner as the patient sample the laboratory was confident in the patient test results produced and were able to meet ISO 15189:2012 requirements.
