Urologist. will urine ph greater than equal to 6.5 lower actual specific gravity? my ph was 7.5 and my sg was 1.015, was the sg lowered in my bladder due to high ph or just dipstick reading. i was neg blood, i know high sg causes false neg for blood?

pH has nothing to do with specific gravity (s. gravity). S. gravity is indeed the urine concentration. Normally, it varies between 1.010 to 1.025 which depends on your body volume PROVIDED your kidney function is normal. When you drink a lot of water, s. gravity will drop below 1.005 and it may mask some abnormalities in your urine because of dilution. S. gravity is above 1.030 with dehydration.

PH indicates acidity or alkalinity of the urine and is variable . Specific gravity is a test for concentration or dilution. The two are independent from each other Your readings are normal and do not affect each other and there is nothing to worry about.
