I don't use one or have diabetes but my understanding is that current CGMs measure interstitial glucose levels, which lag blood levels by up to 15 minutes. As a result, I believe those who require accurate spot measurements rather than just overall trends are still recommended to use finger stick tests.

In the article, the researcher claims "No other technology can provide this level of precision without direct contact with the bloodstream", so it sounds like they're claiming it's better than existing CGMs in a way that might be clinically relevant. Not sure if that's plausible or whether they are directly measuring blood glucose rather than interstitial.

Type 1 here, a 15 min lag is fine. The constant sampling especially overnight and the multiday graphs are what I love about CGM. I've always been in decent but loose control 6.7 to 7.1 A1C (longer term measurement). After a year w CGM I got to 6.5. Now last checkup I'm at 5.9, this ties my record from my first month on Lantus insulin, never repeated in 19 years until now. Also getting numbers on phone and checking number every 15 min while driving are amazing. The stock software for Dexcom and Freestyle are both abysmal. Both refuse to allow silent mode, Dexcom has a hard 6 hours left on sensor uninteruptable alarm, woke me up at 4 am, coustomer service had nothing to say, so Goodbye. I went back to Freestyle their handheld reader is silencable and I use a third party app called Juggluco for my Android phone. Sorry I've survived 42 years on human insulin I don't want software taking over my life w unsilencable alerts. Anyone w less than 10 or 20 years OK, but my brain has extra backup pathways and I'm still functionable down to 50 (very rare), and I can recognize dimished coordination and the emotional shifts that accompany dips. Plus I have life experience to know my low time of day and to watch w exertion.
