Sperm Concentration Testing and Its Role in Male Reproductive Health
The World Health Organization (WHO) includes sperm concentration among the parameters evaluated during standardized semen examination. However, WHO also emphasizes that semen parameters should not be interpreted as absolute boundaries between fertile and infertile individuals. Fertility assessment requires consideration of multiple factors rather than a single measurement. Male reproductive health involves several biological factors, and […]
H. pylori and Gastric Health: From Infection to Laboratory Testing
Helicobacter pylori (H. pylori) is a bacterium that colonizes the stomach and represents one of the most common chronic bacterial infections worldwide. Many infected individuals experience no noticeable symptoms. However, persistent infection can contribute to inflammation of the stomach lining and may be associated with several gastrointestinal conditions. Because symptoms such as abdominal discomfort, nausea […]
Powerful Insights Into Ovulation: LH Testing and Fertility Timing
For people planning pregnancy, understanding when ovulation is likely to occur can help identify the most fertile days of the menstrual cycle. Although cycle-tracking apps and calendar calculations can provide estimates, menstrual cycles naturally vary from person to person and even from one cycle to another. One biological marker commonly used for ovulation prediction is […]
Understanding Influenza A, Influenza B and H1Nx Through Molecular Testing
Seasonal influenza continues to be one of the leading causes of acute respiratory infections worldwide. Although many cases resolve without complications, influenza can lead to severe illness in older adults, young children, pregnant women and individuals with underlying medical conditions. Because influenza viruses continually evolve through genetic changes, molecular laboratory testing plays an important role […]
Why Legionella Testing Matters: Understanding Legionnaires’ Disease
Recent public health events continue to highlight the importance of Legionella surveillance. In July 2026, New York City health officials investigated a Legionnaires’ disease outbreak in Central Harlem, resulting in dozens of confirmed cases before the outbreak was declared over following environmental investigations and control measures. What Is Legionella pneumophila? Legionella pneumophila is a bacterium […]
Essential Guide to Magnetic Bead-Based Nucleic Acid Extraction Systems
Molecular diagnostic workflows begin long before PCR amplification. One of the most important pre-analytical steps is nucleic acid extraction, where DNA or RNA is isolated from biological specimens before downstream molecular analysis. Among the available extraction technologies, magnetic bead-based nucleic acid extraction has become widely adopted in research and clinical laboratories because it supports automated […]
Cyclospora Outbreak 2026: Why Comprehensive Gastroenteritis Testing Matters
The recent multistate outbreak of Cyclospora cayetanensis has drawn renewed attention to foodborne gastrointestinal infections and the challenges they present in clinical practice. According to the Centers for Disease Control and Prevention (CDC), the outbreak has been associated through epidemiological and traceback investigations with recalled iceberg lettuce distributed across multiple US states. Because the symptoms […]
What Everyone Should Know About Hepatitis
Every year on 28 July, World Hepatitis Day brings global attention to one of the leading causes of liver disease. For 2026, the World Health Organization (WHO) has adopted the theme “Hepatitis: Let’s Break It Down,” encouraging healthcare communities, policymakers and the public to break down barriers to awareness, prevention, diagnosis and care. Breaking […]
7 Reasons Molecular Testing Matters for Dengue, Chikungunya and Zika
Dengue, Chikungunya, Zika are mosquito-borne viral diseases that continue to pose significant public health challenges in tropical and subtropical regions. Because these arboviruses are transmitted by the same Aedes mosquitoes and often present with similar early symptoms, laboratory confirmation plays a crucial role in accurate diagnosis and patient management. Why These Viruses Are Difficult to […]
Reliable Inflammation Assessment During Sarcoma Awareness Month
Together, IL-6 and CRP reflect different stages of the inflammation. While IL-6 represents the early cytokine response, CRP provides insight into the subsequent acute-phase reaction. Used alongside clinical evaluation, imaging and pathology, these complementary biomarkers can support a more comprehensive assessment of inflammatory cascade. Understanding Sarcoma Beyond the Tumor Sarcomas are a diverse group […]
