Abstract:
1. A noninvasive method for estimating a variation of glucose level ΔG in the blood of a person within a time interval Δt, comprising the following steps: placing a first tetrapolar electrode device in contact with skin of the person overlying a portion of soft tissue including muscular fibers oriented parallel to the direction of the muscular fibers; placing a second tetrapolar electrode device in contact with the skin of said person overlying said portion of soft tissue oriented transverse to the direction of the muscular fibers; measuring for a time interval Δt: estimating ΔG by a processing apparatus as: wherein: a is in the range of 0.15-1.0 μM/l sec; the low frequency is in the range of 1·×10 “≈” means “equal within a range of +/−2.5%-+/−7.5%”.
