Hello everyone,
If in a urine test it is written negative for sugar level, does that mean you have no diabetes or do we have to have blood test as well?
Thank you very much for your answers.

Although testing the urine for glucose (sugar) was done in the past I thought that it was done no longer. Indeed when I entered medical practice in 1980 the practice had ceased at the hospital where I was on the medical staff. The problem is that there is no correlation between the amount of glucose in the urine and the glucose level in the blood. Your urine glucose may be 4+ while when your blood glucose is 100. In counterpoint your blood glucose may be 500 and your urine glucose test negative. If you would like to know if you have diabetes take your fasting glucose with a glucometer. I certainly hope that you do not have diabetes but you are not able to determine anything from a negative urine glucose. I hope that this is helpful.

Good question.
The body loses glucose through kidneys only when the blood sugar is above 180 mg/dl (that if the kdneys are ok)
so one might have diabetes, but a blood sugar less than 180 (126-180), and still the urine test can be negative.
The only thing that the urine test can tell you is that you didn't have a high blood glucose, in the previous hours.
Yes , 1 or 2 venous plasma glucose measurements are also needed for a clear diagnosis. Diagnosis cannot be made on a glucometer, because the measurement is not that accurate.

I would want a blood test also. It can tell you more than a urine test when I first took diabetes that's what the Dr went by but with advanced testing they found out that you could dump sugar into your urine 2 or 3 days after you had eaten it the blood test were more accurate than the urine test

I am writing to tell you what an incredible impact these methods had on my life! I have had type 2 diabetes for 27 years. For me, the worst part of this horrible disease is the severe pain I constantly get in my feet. The pain is so bad that I avoid standing and walking as much as possible. I've got to tell you that within the first month, my feet stopped hurting altogether and I can now walk totally pain free.
Believe it or not, I even danced at my niece's wedding last month, something I have not done in a many years. I've been following the book for six months now and my blood sugar is well within normal range. I feel great!
I recommend you use the Type 2 Diabetes Destroyer to naturally reverse your diabetes.

It just means your body isn't dumping sugar yet, Blood tests must be done. Thats the only way to make sure. More importantly with a urine test is if you have Ketones... That will tell you if you are burning them instead of sugar.

No. Your blood sugar must become very high before it starts appearing in urine. Your body can suffer significant damage before sugar appears in urine.
