Diabetes

why blood tests are preferred for people with diabetes instead of urine test?

[cardiorrhexis]

Because your blood sugar levels have to exceed 250 before it will show up in urine.

Basically, You can catch an elevation faster by using blood tests.

In healty person you can not see glucose in urine, in a diabetic you can. But for the removal of glucose from the body by urine, it must be reached a high level-which can cause many problems like blindness-. But you can get blood sample and test.

Blindness? I think that is a little exagerated. I have a friend with diabetes and when they identified the desease he had 500. And he can still see very well. Yes, 500, he was close to a coma...

Exagerated? I heard a lot of people become blind because of high glucose level.

PS: A doctor told me that some people can tolerate up to 700-750. A few of course.

I know that blindness does occur.

what do u mean by 250. 250ml ?

[MrMistery]

250 mg/dl of blood.

I take back what i said. Looks like my firend was just lucky.

@Ozge
People can tolerate UP to 700. Not all, it depends on other factors. My friend had a 550 or something... And you can easily go into a coma at 600

[cardiorrhexis]

We see animals with BG levels above 800 completely responsive where another one may come in at 550 in a DKA coma....

I think it's all about individual tolerance.

That's why I said "some people".

There is a diabetes that called "juvenile-onset". It is result from the islets producing too little insulin. As we know the function of insulin is maintain the glucose level. Because too small amount of insulin that produced by the islets.so, the sugar level in the blood is too high . So,blood test preffered to people with diabetes. In order to know the sugar level in the blood.

a blood test is just a more sensitive and accurate way to determine glucose levels. glucose is only excreted in urine when blood glucose levels are too high (however, blood tests can tell you if you're in the low-normal/normal/high-normal ranges). For a diabetic (like my mom) it is VERY important to know when glucose levels are low. (... because you can also die if glucose falls tooo low ... the simple solution? Eat something sweet!!)

Also, factors such as certain vitamins (can't think ofwhich ones) can affect the amount of glucose in urine.

Additionally, urine testing doesn't necessarily give you you're actual glucose level NOW ... the result that you may get from a urine test may actually represent the glucose levels in your urine 1-6 hours before (... cuz we 'store' urine in our bladders for hours at a time)

hope this helps
