Yes you can buy blood testers in many chemists. The only problem I found in Turkey was that I would buy a tester and when I went back some months later to buy a new box test strips they no longer sold them. I was a type 2 diabetic and only needed to test my sugar levels a couple of times a week. This meant that a box of test strips lasted about 4 to 6 months. The test strips are expensive and have a limited life.
The chemist I used would give me a new tester. At one stage I had 8 of them and no test strips.
