Researchers at Howard Hughes Medical Institute Develop Blood Test That Reveals a Patient’s Viral History; Could Reduce Unnecessary Clinical Laboratory Testing

The VirScan test gives doctors insight into a patient’s lifetime exposure to viruses and thus may be developed into a useful medical laboratory test

Scientists and pathologists are learning that blood is like a time capsule, holding precious information about exposure to viruses over the years—chickenpox at five, mononucleosis at 18, flu at 40. You get the idea.

Now, researchers at Howard Hughes Medical Institute (HHMI)  have found a way to tap that entire data stream, so to speak. An inexpensive blood test, they say, reveals every virus that has passed through the body over time.

New Discoveries Could Lead to a Useful Clinical Laboratory Test

The testing method, called VirScan by researchers, is an efficient alternative to current medical laboratory tests that test for specific viruses one at a time, according to an HHMI news statement about the new technology. (more…)

Top Biologists Call for Moratorium on Use of CRISPR Gene Editing Tool for Clinical Purposes Because of Concerns about Unresolved Ethical Issues

Most pathologists know that CRISPR can permanently repair DNA to eliminate diseases that plague families, but also could be used for less ethical purposes, say experts

Gene editing is a rapidly developing field that is expected to create new diagnostic needs that can be filled by pathologists and by new medical laboratory tests. However, experts in bio-ethics are voicing concerns that gene editing for clinical purposes is moving forward without proper consideration of important ethical issues and are calling for a moratorium on use of gene editing for clinical purposes.

What is speeding the development of gene editing is use of the tool known as CRISPR/Cas9. It is a gene-editing tool that makes it possible to genetically modify DNA for therapeutic purposes. It provides medical scientists the ability to repair damaged genes that cause or predispose individuals to disease. (more…)

UCLA Researchers Develop Lens-Free Smartphone Microscope, Pathologists May Be Able to Take the Clinical Pathology Laboratory Just About Anywhere

In a trial, the lens-free microscope invention from the UCLA California Nano Systems Institute enabled a board-certified pathologist to detect cancers and other cellular abnormalities at 99% accuracy

One of our favorite innovators is at it again, this time with a device that could eventually allow pathologists to use a device coupled with a smartphone to view cancer and other abnormalities at the cellular level.

At UCLA, Professor Aydogan Ozcan, Ph.D. is already well known for having invented attachments that use a smartphone’s camera to create a tiny, lens-free microscope. Now Ozcan, who is the Chancellor’s Professor of Electrical Engineering and Bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, has created an inexpensive smartphone device that produces holographic images of tissue samples that allow pathologists to view cancer and other abnormalities at the cellular level, according to a December 17, 2014, Science Translational Medicine (STM) article.

Breakthrough DNA Editing Tool May Help Pathologists Develop New Diagnostic Approaches to Identify and Treat the Underlying Causes of Diseases at the Genetic Level

The advent of the CRISPR/Cas9 genetic editing tool is already generating novel therapies for diseases and will create new opportunities for pathologists and medical laboratories

In just 24 months, a new gene-editing tool has become the hot topic worldwide among researchers working to understand DNA and develop ways to manipulate it for therapeutic purposes. It goes by the acronym CRISPR and it may soon become quite familiar to most pathologists and medical laboratory scientists.

CRISPR stands for clustered regularly interspaced short palindromic repeats. The gene editing platform is known as CRISPR/CAS9. (more…)

UCSF Genomics Diagnostics Team Uses Next-Gen Sequencing as a ‘Laboratory-Developed Test’ to Reveal an Elusive Pathogen’s DNA and Save a Teen’s Life

It took UCSF physicians just 48 hours to identify the bacteria in cerebrospinal fluid that was causing fourteen-year-old Joshua Osborn’s hydrocephalus and status epilepticus

There’s rich irony in the FDA’s  recent announcement that it would move forward with plans to regulate “laboratory-developed tests ” (LDTs) just weeks after the national media published stories about how innovative use of an LDT helped physicians make an accurate diagnosis that saved the life of seriously-ill 14-year old boy.

Pathologists and clinical laboratory managers may be aware of the case of Joshua Osborn. It was a laboratory-developed test that used next-generation gene sequencing in a unique approach that gave his care team the diagnostic information they needed to select the right therapies for his condition.
