In most countries, the Hemocue 201+ Analyzer and accessories (microcuvettes) are licensed only for medical-professional (e.g., physician and nurse) use, and not for patient use, so even having a prescription will often not help you to get it.
Therefore, there are two ways for you to get one. First, you can ask your medical doctor to order one for him/herself and then pass it on to you, in which case you will have to pay him/her for the expenses (usually, less than US$400).
Second, you can find it online from a variety of intermediaries (e.g., www.medicaldevicedepot.com or www.willburnmedicalusa.com or www.tigermedical.com) and even on eBay; some of them ask you if you are a medical professional, but they don't really check if you are; others are more stringent; and some don't seem to care. You will pay for it directly.
You can try getting your insurance company to cover it, but I would be surprised if you succeeded.
