The store kits work quite well, but require a bit more blood that is required from normal finger sticks. Many clinics provide free diabetic screening. If you have diabetes, you MUST be under a physician's care.
You also can get an HA1C test kit at Walgreens and also I believe Walmarts now that will test your blood sugar average for a period of a couple months. For a non-diabetic this number would be in the high 4.0's. For pre-diabetic it would be in the high 5.0's and anything over 6.0 is considered diabetes. At Walgreens I believe these kits are around $25.
Hi,
there is not a test that doesn't involve money.
However, if you can get a blood sugar test kit (and strips) you could test fasting blood sugar (as soon as you wake up and before eating), and 2 hours after meals. If these numbers are high, then you would need to see a doctor.
Keep an eye out, there may be free blood sugar testing offered by some pharmacies / in malls from time to time.
Why do you think you have diabetes? WHat are your symptoms?
In the meantime, if you even suspect a problem you need to watch what you're eating (google diabetes and diet and you'll get lots of good info), and try to exercise for at least 30 minutes to 1 hour every day.
