Researchers have developed a handheld cancer-screening device capable of detecting early-stage cancer biomarkers from just a single drop of blood. Developed by Westlake University in China, this new technology shrinks refrigerator-sized laboratory equipment into a portable device while boosting detection accuracy.
To catch the faint signals of early-stage tumors, doctors required huge apparatus packed with complex optical paths, expensive spectrometers, and sensitive prisms. Moreover, these multi-hundred-dollar tests stayed locked inside specialized institutional laboratories, miles away from the patients who needed them most
Thank God he’s in China, I would be worried if they were in the US given the many disappearances happening there lately.
Isn’t that pretty much the accuracy of a cardboard box with „No“ written on it?
Accuracy alone is a terrible metric for that, because there’s a huge imbalances between positive and negative groups.
You can just say „No cancer“ every time and get 90-something percent accuracy, while being completely useless.
As a pathologist, until I actually see this in actual practice a lot of this sounds very reminiscent of the Theranos era, and I am somewhat skeptical.
94.9% accuracy is pretty terrible from a medical perspective, fwiw. Baye’s theorem, for the uninitiated
The accuracy comes from the detector is natively carcinogenic itself, therefore.. . . Smh.
This presents the data in a somewhat misleading manner. It might good as a screening tool, but you would need more than one POC test to evaluate for cancer recurrence. It is a neat application of technology though
Layman as I am, I don’t get it.
We’ve been cheaply and quickly detecting tumor markers for decades now.
OTOH, if this test detect tiny pieces of the tumor itself, then it’s not early stage cancer, no?
What am I missing?
Imagine how spicy TSA checks could be when combined with a metal detector wand. „Did you have your knee replaced?“ „No? You have cancer, have a good flight.“
Neat, they use some kind of refractometric technique to detect extracellular vesicles.

Sounds like what Theranos promised… But hopefully real.

1 in 20 wrong? If that’s being used as preventative scanning, that could be a false result every day in just one doctor’s office. Imagine how many false readings this would register in a city full of doctor’s offices.
I really wish I could have that test done. Instead we’re forced to visit a doctor to be referred to another to be referred to another to have it declined by our insurances.
I made a handheld cancer detector with 94.6% accuracy.
It’s an index card, and I wrote „No Cancer“ on it.
When I hold it up to a random person, it’s accurate 94.6% of the time.
