Researchers say high accuracy of this $150 portable optical spectrometer enables mobile diagnostic technologies to achieve pathology test results comparable to traditional spectrometers costing far more
What’s the latest thing in a smartphone diagnostic device? It’s a multi-channel smartphone spectrometer! Researchers at Washington State University (WSU) designed the device to detect human cancer biomarkers. It’s hoped that this device can improve cancer detection in rural areas where clinical laboratories may not be easily accessible.
The Multichannel Smartphone Spectrometer (MSS) is a highly accurate, low-cost, portable diagnostic device capable of detecting human cancer biomarkers equally well in rural and busy hospital settings. (more…)

High rates of variability from one drop to another raise questions about the reliability of point of care testing equipment and companies that collect lab specimens only with finger sticks
Since last fall, one news report after another has come out with bad news for Theranos Inc., the high-profile medical laboratory company. The reports have ranged from dissatisfaction among Theranos’ partners, such as Walgreens and Capital BlueCross, to failed inspection reports from the federal Centers for Medicare and Medicaid Services (CMS) and the U.S. Food and Drug Administration (FDA).
In response, the embattled lab company in Palo Alto, Calif., has maintained that it is doing everything it can to correct any deficiencies in its clinical laboratory testing methods and to ensure its partners that its processes are scientifically sound and its methods valid. (more…)

Researchers determined that as many as nine successive capillary blood drops must be collected and tested to achieve results that would be comparable to testing with venous blood
A new study is raising questions about the implications of using fingerprick blood samples for point-of-care tests. Done by researchers at Rice University’s Department of Bioengineering, the study suggests clinicians use measurements with caution when assessing patients’ conditions based on the results of clinical laboratory tests using a single drop of capillary blood collected by fingerstick.
Pathologists and clinical laboratory scientists were quick to call attention to the study, based on the press release Rice University issued. That’s because, for almost 30 years, medical laboratories have struggled to correlate the results for such biomarkers as glucose. It is common for capillary blood specimen collected by finger stick and tested on a point-of-care device to produce different results for the same patient when compared with that of a venous specimen tested on the automated, high-volume analyzes in a central laboratory. The Rice researchers offer useful insights about such variation. (more…)

Researchers at Florida Atlantic University believe this technology could also be used to detect bacteria in food and water and to follow patients’ progress after leaving acute or outpatient care
New technology could shift the paradigm in infectious disease testing by clinical laboratories, while also giving hospitals a faster way to identify hospital-acquired infections (HAIs) and monitor patients for infections post-discharge. The diagnostic technology is built into a special “biosensing film” made of cellulose paper and a flexible polymer.
Researchers at Florida Atlantic University (FAU) developed the biosensing film. They say it can detect and discern HIV, Staphylococcus aureus, E-coli and other bacteria in blood, plasma, and saliva. The test is inexpensive, disposable, and portable. Best of all (at least for developing countries, remote locations, and places that have few resources), it requires no expensive infrastructure or a clinical laboratory.
And yes, the biosensing film is designed to work in tandem with a smartphone app. But in this case, the mobile app is only part of the story. The real genius is the piece of lightweight, flexible, “electronic paper” or “biosensing film” used with the app. The film acts as a platform that detects infections, both viral and bacterial.
The story of this inventive biosensing film is detailed in a Scientific Reports article in the March 5, 2015, edition of Nature. (more…)

This diagnostic instrument would be preferred by patients and physicians alike because it is noninvasive and provides immediate results
Dermapathologists will be interested to learn about a new handheld, point-of-care (POC) device that images melanoma tumors and enables the in vivo diagnosis of melanoma.
Because this diagnostic technology is noninvasive and provides immediate results, it is likely to be preferred by patients and doctors alike and could thus substantially reduce the volume of skin biopsies referred to dermapathologists and pathology laboratories. (more…)
