Antibody validation standards would help ensure reproducibility of research studies and improve the consistency medical laboratory test results
As science and industry gets better at measuring things and assessing quality, the acceptable standard often comes into question. This seems to be happening with antibodies, the most common reagents used in diagnostics, clinical laboratory diagnostic tests, and medical research. In many cases, the end result is that companies and their suppliers must use new technologies and quality methods to revise the “old way” and create products that have measurable better quality.
The techniques currently used to validate antibodies is the topic of a recently-published scientific paper. The authors of a paper published in the March, 2010, issue of Biotechniques pointed out, antibody validation and standardization ensure study reproducibility, which is critical to accuracy. And yet, no standard guidelines define how these important biological tools should be validated prior to use.
Thus, researchers participating in a recent webinar, presented by The Scientist expressed concern that—without improved antibody validation and standardization—the accuracy of published research is in question and diagnostic test results, such as those produced by medical laboratories, will continue to be inconsistent.

Sequencing this new DNA standard reference material enables medical laboratories to verify if their DNA test results are accurate
To reduce the variability in genetic test results that has been observed across different clinical laboratories and pathology groups, the National Institute for Standards and Technology (NIST) has introduced a new standard DNA reference. This is another step forward to improve transparency in the quality and accuracy of genetic test results produced by medical laboratories in the United States and abroad.
Even as scientists continue to identify genetic mutations that could cause various cancers and other diseases, such as Alzheimer’s and cystic fibrous, studies have demonstrated that DNA test results from the same specimen can vary depending on which medical laboratory performs the whole-genome sequencing analysis. This is partly due to variances in the technology, chemicals and processes used for the testing. Therefore, ensuring consistently reliable test results has been difficult, which could lead to inaccurate or missed diagnoses.
That is why a new standard DNA reference material developed by the National Institute for Standards and Technology has the potential to help DNA sequencing facilities to verify if their DNA test results are accurate. The new reference material, NIST RM 8398, was designed to improve the accuracy of diagnostic laboratories that analyze DNA using “next-generation sequencing” (NGS) technology. (more…)

Drugs based on knockout genes are expected to trigger the need for companion diagnostic tests that will be performed by pathologists and medical laboratory scientists
Pharmaceutical companies and other research programs are developing a new opportunity to use information from human genome sequencing to create a new class of therapeutic drugs. These drugs target “knockout genes” and those same genes are expected to be used as diagnostic biomarkers for clinical laboratory testing as a new field of companion diagnostics emerges.
In simplest terms, large-scale DNA sequencing of the human genome is enabling researchers to identify individuals with “knockout” genes and then develop therapeutic drugs based on that knowledge.
The first commercial success story from this partnership of geneticists and the pharmaceutical industry is expected to be a new class of drugs that lowers cholesterol. These drugs may reach pharmacy shelves this year, reported an October 24 Nature article. (more…)

If the clinical study validates this patient-friendly, non-invasive approach to diagnosing lung cancer, it could eventually mean fewer referrals of tissue biopsies to medical laboratories
For almost a decade, pathologists have seen a regular stream of news stories about technologies that utilize a sample of human breath to diagnose a disease or health condition. Now comes news that just such a diagnostic test for lung cancer is beginning clinical trials in the United Kingdom.
The clinical trials will evaluate breathalyzer technology developed by Engineer Billy Boyle, M.S., Co-founder and President of Operations at Cambridge-based Owlstone Ltd.. The clinical trials of this new breathalyzer technology to detect lung cancer are taking place at two National Health Service (NHS) hospitals: University Hospitals of Leicester and Cambridge’s Papworth Hospital in the United Kingdom.
The reason why so much research is happening in this field will be familiar to clinical laboratory managers and pathologists. Use of volatile organic compound (VOC) biomarkers in breath to diagnose disease is an ideal concept because it is convenient, non-invasive, and well tolerated by patients. However, until the start of this clinical study, researchers have explored the potential of this diagnostic approach for some time, but with limited success. (more…)

Hospital-based pathologists may soon gain a new diagnostic assay that could prove effective in detecting hospital-acquired infections more quickly and more accurately than with existing rapid molecular diagnostic tests
Imagine a diagnostic assay designed for hospital settings that uses a specimen of the patient’s breath, can be performed at the bedside, and can detect early-stage infections within two hours of onset. Pathologists and clinical laboratory managers will recognize that a diagnostic test such as this could play a big role in helping hospitals reduce hospital-acquired infections (HAI).
That’s just one application that Madison, Wisconsin-based Isomark has for the new breath analyzer test it is developing. The company says that its diagnostic test is capable of detecting early metabolism and immune system changes based on reading carbon dioxide (CO2) in a patient’s breath.
Canary Could Affect Volume of Clinical Laboratory Specimens
The Isomark Canary Breath Analyzer test (Canary) was specifically designed to identify infections before they have a chance to overwhelm the patient’s immune system. Canary has so many potential uses for identifying infection early that, if the technology were cleared for clinical use, medical laboratories could eventually see a significant reduction in the volume of patient specimens coming into the microbiology department.
