For measuring the blood sugar one has to puncture the fingre, take blood sample and measure the blood glucose.

But now this is not required.

Now noninvasive type gluco-meters are available called Gluco-watch it gives reading for every half an hour.

Also breath analyzers are available which measures Methyl Nitrate in breath
which indirectly measures glucose in blood.

Can anybody give the names of reliable suppliers ?
