Mt. Sinai researchers find Theranos blood tests produce problematic results

Beleaguered blood test company Theranos has been accused of overstating the abilities and accuracy of its Edison test. Now, researchers at the Icahn School of Medicine at Mt. Sinai in New York have conducted a study of the company's test, according to a Forbes report. The results raise a number of questions.

The Mt. Sinai researchers compared results from Theranos' test with results from its rivals Laboratory Corp. and Quest Diagnostics. The study found Theranos sample collection had a higher rate of sample rejection. Additionally, the Theranos test gave cholesterol readings consistently five to 10 points too low, according to Forbes.

Theranos responded with a letter calling the study "flawed and inaccurate." The company argues the study authors' cholesterol readings were flawed as a result of their collection methods.

The study authors concluded laboratory practice standards would benefit from increased transparency and evaluation. Forbes concluded its article by calling for Theranos to make data on its tests public.
