For Embattled Medical Laboratory Company Theranos, Bad News Keeps on Coming After Two Federal Inspections Show Problems in Certain Lab Practices

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…)

Rice University Researchers Publish Study about Variation in Drop-to-Drop Samples of Capillary Blood Collected by Fingerprick and Used for Clinical Laboratory Testing

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…)

Internationally-respected Experts in Clinical Pathology and Laboratory Medicine Ask: Why Don’t We Know More about Theranos’ Technology?

This secretive start-up medical laboratory testing company has not disclosed how its diagnostic test technology works, nor has it given laboratorians an opportunity to examine the technology

Several internationally-respected clinical laboratory experts are asking serious questions about Theranos and its diagnostic testing technology, and they’ve gotten few answers to date. Though the number of experts is small, their credentials in the clinical laboratory profession are impressive. In addition, some have published their critiques of the start-up medical laboratory company in well-respected medical journals.

One question these clinical pathologists and laboratory directors ask is why Theranos has so far been unwilling to provide more information about the lab testing technology it uses to deliver medical laboratory test results to patients and their referring physicians. Even as the company has declined to speak to the medical laboratory profession, Theranos has mounted a major public relations campaign designed to make a big impression on investors, business partners, and most recently on health insurers.

The clinical laboratory company in Palo Alto, Calif., gets plenty of attention because it claims to have disruptive technology that will allow it to perform medical laboratory tests equivalent to the current standard of care. Theranos says it can do this using a capillary specimen and return results in four hours, while charging a price that is just 50% of Medicare Part B lab test fees. Given these assertions, it is natural that pathologists and laboratory scientists who perform tests for patients, are curious about the scientific basis of Theranos’ proprietary diagnostic technology and what evidence Theranos has developed to support its claims of comparable accuracy and reproducibility.
