High HbA1c Levels Do Not Always Lead to Diabetes

Prediabetes is an asymptomatic condition preceding type 2 diabetes. It is characterized by hyperglycemia, which is defined as a blood glucose level that is higher than normal but below the level for a clinical diagnosis of diabetes. More...

Collagen Biomarkers Clarify Prognosis of Diabetic Renal Complications

Type 1 diabetes, once known as juvenile diabetes or insulin-dependent diabetes, is a chronic condition in which the pancreas produces little or no insulin. Insulin is a hormone needed to allow sugar (glucose) to enter cells to produce energy. More...

Neutrophil‐Lymphocyte Ratio and Lactate Predict Mortality in Septic Patients

Sepsis is the primary cause of death from infection. It is also one of the leading causes of intensive care unit (ICU) mortality, despite early administration of antibiotics and hemodynamic management. More...

Antibody Tests Recommended for Parasitic Infection Diagnosis

Pleural parasitic infestation (PPI) is a disease prevalent in certain parts of the world and it is frequently misdiagnosed due to its lack of standardized diagnostic criteria. The clinical manifestations are non-specific and many patients are initially treated for tuberculosis or misdiagnosed as lung cancer. More...
