Clinical chemistry has evolved far beyond its beginnings of blood and urine analysis. Advanced techniques such as enzyme measurement, electrophoresis, and immunoassays have made their impact on the field, expanding its diagnostic capabilities. Keep reading for advances in automation and clinical chemistry applications for toxicology, urinalysis and much more.
A research group established a microfluidic control technology that can be applied to small blood testing devices and consequently developed a novel integrated immunoassay device.
A team of researchers has discovered a new method of measuring levels of cortisol directly from a blood sample - a significant step forward in diagnosis and treatment of a wide range of diseases.
A new synthetic antibiotic developed by University of Liverpool researchers is shown to be more effective than established drugs against ‘superbugs’ such as MRSA, a new study shows.
What role should artificial life play in medicine? Researchers from Denmark and the US explore the potential of hybrid peptide-DNA nanostructures for diagnosing and treating diseases.
US scientists report using a single-atom-thick nanomaterial to simultaneously detect Covid-19 and flu viruses — at much lower levels and much more quickly than conventional tests for either.
Urine screening tests using only immunoassays are the most common procedures used to identify drug abuse. They are inexpensive, automated, and produce rapid results. But they may generate false-positive or false-negative results, which vary based on the drug, drug class, and the assay used. Hair toxicology analysis is another form of drug testing which, unlike urine tests, enable analysis of drug…
Clinical laboratories need to be proactive to attract transgender patients for testing and to ensure that they are comfortable with the services provided. This issue is of great importance to the American Association for Clinical Chemistry (AACC), which conducted a scientific session on transgender health at its recent annual meeting in Chicago.
Researchers have identified an enzyme that is a promising new therapeutic target to combat the dangerous bacterial disease melioidosis.
Researchers created a special ultrathin sensor, spun from gold, that can be attached directly to the skin without irritation or discomfort. The sensor can measure different biomarkers or substances to perform on-body chemical analysis.
Researchers have shown that aggregation of amyloid-beta, one of two key proteins implicated in Alzheimer’s disease, causes cells to overheat and ‘fry like eggs.’
Liquid profiling is offering clear benefits in terms of cancer diagnostics and targeted therapy, but challenges remain in bringing it into the clinic.
Hyaluronic Acid LT Assay is an in vitro diagnostic test (IVD) for the quantitative determination of hyaluronic acid based on the latex agglutination method. This turbidimetric method can be applied to general clinical chemistry analyzers.
Scientists at Queen’s University Belfast have invented a tiny indicator that changes colour if a patient’s wound shows early signs of infection.
Autokit CH50 Assay is an in vitro diagnostic (IVD) test for the quantitative determination of total complement activity in human serum. The complement system is a part of the immune system that enhances/complements the ability of antibodies and phagocytic cells to clear pathogens from an organism.
Non-Esterified Fatty Acids (NEFA) are one of the most important metabolites and energy source of peripheral tissues. The amount of NEFA in serum decreases by physical exercise and increases by starvation, cold or smoking. An increase or decrease is also observed in diabetes, hepatic, or endocrine diseases.
A new method involving deuterium can be used to stabilise compounds against degradation. This discovery could result in new drugs that can be taken in lower doses or less frequently.
Ion-mobility spectrometry (IMS) offers opportunities for rapid diagnosis and clinical decision-making due to breath analysis. As a rapid separation tool, it has clinical value in the identification and analysis of proteins, peptides, lipids, and glycans. The tool is already used as an exhaled drug monitor for anaesthetised patients. It is flexible, portable and has use for point-of-care testing,…
When patients are admitted to a hospital emergency room (ER) it is immediately vital to determine whether s/he has Covid-19. However, with a regular PCR test a result can take up to a few hours. Thus, initially, the patient must be isolated. During the height of the corona pandemic last year, researcher Ruben Deneer from Eindhoven University of Technology (TU/e) and clinical chemist Arjen-Kars…
Integrating laboratory functions on a microchip circuit is helping improve the cost-effectiveness of drug development. So-called ‘lab-on-a-chip’ or ‘human-on-a-chip’ technology can highlight which treatments may, or may not, work before advancing along the clinical trial process. It can also have benefits for chronic and rare diseases, as well as helping shape personalised medicine.…
