@kimmonismus posted on Friday that Quest Diagnostics, serving about half of US hospitals, disclosed a breach of its Quanum lab portal, with up to about 100 million patient records possibly exposed. The post drew about 1,400 likes.

The figure is an upper bound as relayed in the post. The post does not say what kind of data was taken.
