No needle, no lab, just your wrist.
There is no tech available that you can clip on your finger like a pulse oximeter that reads your sugar.
And there's no tech that's available that you can wear as a watch.
or a ring for that matter, that checks your sugar.
I think a lot remains to be seen with a feature like Health Guardian and more broadly, how well risk sensors and estimates compared to real clinical blood work in the long run,

The University Health Network released a study outlining the benefits of smartwatch use, saying, data from a consumer smartwatch can detect early signs of worsening health in people living with heart failure, often days to weeks before unplanned medical care is needed.

Meanwhile, Concordia University looked at and cautions users on the privacy implications, saying a simple 30-second electrocardiogram, ECG reading from a smartwatch, could accurately estimate a person's age.

I saw a TikToker saying that her watch detected a drop in her blood sugar and it actually saved her life.

Oh, why not? The influencers say it uses optical sensors to read your glucose through your skin, which means no needles.

They warned that they have not authorized or approved any smartwatch or smart ring to measure blood glucose on its own without piercing the skin.

An article from the Associated Press quoted Dr. Robert Gabbay of the American Diabetes Association saying that using unapproved smartwatches for blood sugar could result in potentially devastating consequences.
