As far as I know, noninvasive blood test machine for glucose still not yet available in HK at present. (Major concern is stability & accuracy of glucose level.)
Undoubtedly, noninvasive test for glucose level is currently a hot topic of development.
At present, we still rely on traditional glucometer which required using lancet for blood drop collection (in fact already much less traumatize compared with older generation lancets) . Besides , after stabilization of DM control, can possibly reduce frequency of self monitoring of blood glucose level (after discussion with your doctor).
