User avatar Hi Monica2980,

The urine test for blood sugar is an indirect measure of blood sugar levels. When the blood sugar levels rise above a certain level (variable but usually around 180) the kidney is no longer able to reabsorb all the filtered sugar and sugar begins to rise in the urine. The tests are quite accurate.

There are other tests that can be used to look for rising blood sugars. These include fasting blood sugar levels and a test called Hemoglobin A1c. The Hemoglobin A1c is a long term measure of blood sugar levels. If they are generally elevated this test will show an elevated level.

Typically, diabetes begins to present with increasing thirst, increased urination and increased hunger. Type 2 diabetes (insulin resistance) that commonly goes along with obesity can often be somewhat asymptomatic so occasional testing is reasonable. The urine test is nice in that it doesn't need a painful blood draw and can be done rapidly in the office. One may also notice a darkening of the skin around the neck and on the knuckles. This would be an indication of insulin resistance and can be an early indicator of developing diabetes.

Best wishes.

Thanks Doctor for answering my question, so do you think my son needs to have a blood test done or with the urine test is enough?my son does not have any symptoms but since he's obese then they decided to do the urine test.now the doctors worried me and i'm thinking about the blood test,but i just don't want my son to go through that trouble if he really doesnt need it,what do you think?

User avatar If he does not have any other symptoms the urine test should suffice. If you are concerned or if there are other symptoms it is very reasonable to test his blood.

Best wishes.
