Exhaled Breath Test Discriminates COPD

Chronic obstructive pulmonary disease (COPD) is a type of obstructive lung disease characterized by long-term poor airflow. The main symptoms include shortness of breath and cough with sputum production. COPD is a progressive disease, meaning it typically worsens over time. More...

Lab Evidence Confirms Outbreak of Haff Disease

Haff disease is a syndrome of unexplained rhabdomyolysis following consumption of certain types of fish, and it is caused by an unidentified toxin. Rhabdomyolysis is a clinical syndrome caused by injury to skeletal muscle that results in release of muscle cell contents into the circulation. More...

Enhanced Immunoassay Validated for NGAL

The ectopic expression of Neutrophil Gelatinase-Associated Lipocalin (NGAL) has been reported in patients with various malignancies such as kidney, colorectal, gastric, pancreatobiliary, hepatic, breast, gynecological and hematologic cancers. More...

Cholesterol Test May Help Assess Heart Disease Risk

Researchers have developed a first-of-its-kind rapid assay for measuring effectiveness of a patient’s high-density lipoprotein cholesterol (HDL-C) in cleaning up arterial cholesterol. This HDL-C function test could improve risk assessment and diagnosis, and help provide and monitor more personalized treatments for cardiovascular disease (CVD) patients. More...

Specific Biomarker Assessed for Cartilage Degradation

Osteoarthritis (OA) is one of the most common forms of musculoskeletal disorders and one of the major causes of pain and disability in the adult population. Viscosupplementation is a symptomatic treatment of the knee osteoarthritis based on the intra-articular injection of hyaluronic acid (IAHA). More...

Pre-Op Cholesterol Level Predicts RCC Patients Survival

Renal cell carcinoma (RCC) is the most frequently diagnosed renal malignancy. The constant advances of modern imaging technologies and the percentage of incidentally detected renal tumors has constantly increased during the last couple of decades, and a good percentage of patients are still diagnosed with metastatic renal cell carcinoma (mRCC). More...

Image: The Quo-Test HbA1c fully automated analyzer uses patented boronate fluorescence quenching technology to measure glycated hemoglobin from a 4 μL sample taken from a finger prick or venous whole blood (Photo courtesy of EKF Diagnostics).

POC Analyzer Compared with HPLC Method

The measurement of the glycated fraction of hemoglobin (HbA1c) has been recommended to diagnose diabetes, in addition to monitoring glycemic control. HbA1c reflects long-term glycemic control over the preceding two to three months as opposed to glycemic control at a single point in time. More...
