What lab result indicates the need for further investigation in a patient with diabetes?

The presence of microalbuminuria detected on lab testing is an important lab result for patients with diabetes that warrants further investigation. Microalbuminuria indicates an early stage of kidney damage or dysfunction, which is a common complication in individuals with diabetes due to prolonged high blood glucose levels. Identifying this condition allows for timely intervention to potentially slow the progression to more severe kidney disease, such as diabetic nephropathy.

Microalbuminuria signifies that there is a leakage of protein into the urine, which is not typically present in healthy individuals. Monitoring and addressing this finding is crucial in managing the overall health of diabetic patients, making it a key indicator for further diagnostic evaluation and possible modifications in treatment, such as the initiation of angiotensin-converting enzyme (ACE) inhibitors, even if hypertension is not present.

On the other hand, an A1c of 5.5% is within the normal range and typically indicates good glycemic control. An LDL-cholesterol level exceeds the threshold considered acceptable for patients with diabetes, but this value alone does not necessitate immediate investigation compared to the implications of microalbuminuria. Normal triglyceride levels are indicative of a lower risk factor regarding lipid-related complications and do not warrant further immediate investigation either.
