<i>“The biggest problem in detection of such cells is that these cells are extremely rare- one in a billion blood cells,” says Goda.</i><p><i>According to Goda, the cutting edge device now harbors an unprecedented false-positive rate of one cell in a million.</i><p>For anyone who has forgotten statistics like me and was thrown off by this: <a href="https://en.wikipedia.org/wiki/Type_I_and_type_II_errors#False_positive_rate" rel="nofollow">https://en.wikipedia.org/wiki/Type_I_and_type_II_errors#Fals...</a><p><i>The false positive rate is the proportion of absent events that yield positive test outcomes, i.e., the conditional probability of a positive test result given an absent event.</i>
What are the advantages of this over regular flow cytometry? I guess it would allow instant imaging of morphological changes, but this would require staining anyway (right?) at which point one could use flow to separate out suspicious cells and image at one's leisure using more conventional techniques.
