While Theranos' promises to revolitionize the blood testing industry never materialized, some recent developments may be moving testing out of the labs and into clinics.
Oct. 25, 2021 -- Once valued at over $9 billion dollars, it seemed like Theranos was going to change the world of routinetesting. Their claim was revolutionary: Using blood from a finger prick, they could run over 200 different tests. With a trip to a local pharmacy, someone could get testing done without getting blood drawn and receive the results in hours, rather than days.
Unlike the world of computing technology, where one breakthrough can revolutionize the entire field, progress in blood analysis is steadier and slower, like the automotive industry, Campbell says. While the automotive industry has developed hybrids and electric vehicles, the foundations of a car have remained the same.
“You're literally able to take the capillary sample, place it on your test strip, put it into your device, and this simple one-step chemical reaction takes place in that testing chamber so that you can get a glucose measurement,” says Kimberly Sanford, MD, president of the American Society of Clinical Pathology.
To really get your bang for your buck, the tests need to be easy, fast, and, most importantly, accurate. Unless these in-office tests can provide clinicians with all the information they need to make a medical decision, it makes more sense to send off samples to a lab. “They're similar technologies to what we would use in the main laboratory on the larger analyzers, but they miniaturize them make them more portable,” says James H. Nichols, PhD, a professor of pathology, microbiology, and immunology at Vanderbilt University Medical Center in Nashville.
While the device was designed for urgent care settings, it is now also used at health fairs, medical tents at events, and many other mobile care settings, Nichols says.
