No, diabetes has no effect on blood alcohol content. That depends on what type of test you are referring to...

It may not affect the actual blood alcohol content, but it CAN cause false positive test results... THAT is why the result is called a FALSE positive.

What do you do if pregnancy tests give different results?

Usually different results from pregnancy tests come from using the test too early. Taking the test too soon will cause a test to read a false negative. Some HPT are more sensitive than others, they will read positive sooner than a less sensitive test. False negative results are very common from using the test too early, false positive is almost unheard of unless the test kit was damaged somehow. Always check the kit before using it, including the expiration date and follow directions.
