Glossary: HPLC in Laboratory Medicine

  • News

High-Performance Liquid Chromatography (HPLC) has become an indispensable analytical method in laboratory medicine over the past few decades. Its versatility, precision, and sensitivity make it a valuable tool for a wide range of clinical applications. In clinical chemistry, HPLC is frequently used to determine drug levels as part of Therapeutic Drug Monitoring (TDM). A study by Smith et al. in 2019 showed that HPLC-based TDM led to a significant improvement in patient outcomes in dose adjustment of immunosuppressants after organ transplantation[1]. The method allows for precise quantification of active ingredients such as tacrolimus or cyclosporine A in the blood, enabling individualized therapy management. Another important area of application for HPLC in laboratory medicine is the diagnosis of metabolic diseases. HPLC has established itself as the gold standard in the analysis of amino acids in plasma for the detection of inborn errors of metabolism. A study by Johnson et al. (2020)… 

Lab Tip: Avoid Gas Accidents

  • News

Gas generators offer a safe and efficient alternative to conventional gas cylinders in laboratory environments[1]. By generating gas on demand, they minimize the risks associated with storing large quantities of gas, such as explosions, leaks, and oxygen deficiency[1]. Statistics show that gas accidents in laboratories lead to numerous injuries and even fatalities annually. According to a study by the U.S. Chemical Safety Board, over 120 serious laboratory accidents occurred at U.S. universities between 2001 and 2018, many of which were attributed to the improper handling of gases. Gas generators offer several advantages over gas cylinders. They ensure consistent gas quality and supply without interruptions, increasing the reliability of laboratory processes[1]. Furthermore, they can reduce operating costs by up to 50% by optimizing gas consumption and reducing expensive maintenance work. Another advantage is environmental friendliness: avoiding the transport and disposal of gas cylinders reduces the carbon footprint…

Lauterbach at the end? Tagesschau outs “Lex Lilly”

  • News

In the German healthcare system, lobby groups play a significant role in shaping laws and reforms. Numerous interest groups try to influence political decisions and shape legislation in their favor. Among the most influential lobby groups are the associations of the pharmaceutical industry, primarily the Association of Researching Pharmaceutical Companies (VFA), which represents the interests of 42 major pharmaceutical companies[4]. The VFA is considered particularly assertive and has considerable financial resources for its lobbying activities. An example of the pharmaceutical lobby's influence is the current discussion about the planned Medical Research Act. It is intended to introduce a regulation that allows drug manufacturers to keep the reimbursement price for their medications secret[5]. This change is already being referred to as "Lex Lilly" in expert circles, as it would particularly benefit the US pharmaceutical giant Eli Lilly. It is noteworthy that government representatives have met with the management of Eli Lilly a total of seven times since November 2023,… 

Inside Roche:  Strategy & Pipeline 2025

Roche is banking on a promising drug pipeline to generate future growth and maintain its position as a leading pharmaceutical company. The Basel-based group focuses on five therapeutic areas: oncology, neurology, immunology, ophthalmology, and metabolic diseases. Roche’s pipeline currently includes seven candidates with blockbuster potential, each capable of generating at least 3 billion Swiss francs in annual sales if successful. Four additional drug candidates have the potential for revenues between 2 and 3 billion francs. Among the most promising prospects are therapies for Alzheimer’s disease and obesity, which Roche claims could revolutionize treatment standards. To increase research efficiency, Roche plans to reduce costs for new candidates by 20 percent until market launch and shorten the development cycle by 40 percent. In the long term, the company aims to bring two groundbreaking drugs to market annually. Roche is not only relying… 

Nanoparticle infusion works against clogged arteries

Artery inflammation is one of the main causes of cardiovascular disease – the No. 1 cause of death in the U.S. This inflammation is accompanied by the formation of dangerous plaques in the arteries. Advanced treatments are needed to combat this inflammation in patients. Researchers at Michigan State University have tested a new nanoparticle nanotherapy infusion that specifically targets inflammation and activates the immune system to support the removal of plaque in the arteries. Smith and his team, including lead authors Yapei Zhang and Manisha Kumari, created nanoparticles – materials thinner than a human hair – that they used to develop a nanotherapy infusion. The nanotherapy specifically targets a certain type of immune cell that penetrates the plaque and becomes part of the plaque. These treated cells “eat away” parts of the plaque core, removing it from the artery wall and reducing the extent of blood vessel inflammation.  Previous… 

FDA Approves New Treatment for Hemophilia A or B

Today, the U.S. Food and Drug Administration approved Hympavzi (marstacimab-hncq) for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients 12 years of age and older with hemophilia A without factor VIII inhibitors or hemophilia B without factor IX inhibitors (neutralizing antibodies). Hympavzi is a new type of drug that, rather than replacing a clotting factor, works by reducing the amount, and therefore, the activity of, the naturally occurring anticoagulation protein called tissue factor pathway inhibitor. This increases the amount of thrombin, an enzyme that is critical in blood clotting, that is generated. This is expected to reduce or prevent the frequency of bleeding episodes.

Acute health hazard: Radon contaminates Germany

  • News

Radon represents an underestimated health hazard in Germany. The radioactive noble gas is formed during the decay of uranium in the soil and can accumulate in buildings, where it becomes the second most common cause of lung cancer after smoking[1][2]. Distribution and Exposure The average radon concentration in German homes is about 65 becquerels per cubic meter (Bq/m³)[5]. However, there are significant regional differences: significantly higher values are measured in mountainous regions such as the Black Forest, the Ore Mountains, and the Bavarian Forest. There, concentrations in basements and living areas can reach 1,000-10,000 Bq/m³ or more[3]. According to estimates by the Federal Office for Radiation Protection (BfS), about 10.5 million people in Germany are exposed to radon concentrations of over 100 Bq/m³ in their homes. For just under 2 million people, the values even exceed 300 Bq/m³[5]. Health Effects The risk of developing lung cancer increases linearly with radon concentration and duration of exposure. Per 100 Bq/m³ increase…

JRC improves diagnosis of genetic blood diseases

  • News

To support the standardization of blood tests across different laboratories, the JRC develops clinically certified reference materials (CRMs). These control materials form the basis for reliable and stable clinical measurements. A CRM is usually supplied in a "bottle," a sample with a known amount of the substance to be measured, like a gold standard for laboratory tests. When laboratories use these CRMs, they can be sure that their results are correct and precise. The JRC has now released a new CRM to support the fight against beta-thalassemia. This genetic blood disease reduces the production of hemoglobin, the iron-containing protein in red blood cells that transports oxygen throughout the body. It can lead to severe anemia, and patients may require lifelong blood transfusions. In extreme cases, untreated beta-thalassemia can lead to death. The disease occurs worldwide but is more common in Mediterranean countries. In Italy, approximately…
