I was among the multitudes who attended Elizabeth Homes’s presentation about Theranos at AACC in Philadelphia. Overall, I was impressed and here are some details. First, she said she wasn’t going to address past malfeasances (not the way she put it) but focus on Theranos’s new instrument.
As an aside, she had an identical accent to that of Mira Sorvino in “Romy and Michelle’s high school reunion”). For those who haven’t seen the movie, I would call this “adult valley girl”.
Her presentation included a lot of data analysis. Terms like ANOVA, Passing-Bablok regression, weighted Deming regression, CLSI guidelines EP05-A3 and EP09-A3, ATE (allowable total error) and others were pronounced and used correctly. (The ATE corresponded to CLIA limits). Having worked most of my career for manufacturers, there is a simple rule manufacturers never show bad data. Hence, until these data are reproduced by others….
The instrumentation was impressive from the standpoint that so many different assay types could fit in one relatively small box, but the technologies with which I am familiar were standard – nothing’s new. I don’t recall her mentioning any specific reagents. When you think about assays, reagents are the ballgame – the instrument is not that special. Something that did seem new was that the software for the instrument (the minilab) is in a central server. The advantages of this remain to be demonstrated.
