D's has suspected HSP which can damage kidneys. Did his 1st dipstick test this morning with fmu and protein and blood is normal which is great but specific gravity is the light brown one at the end (1.030), is this anything to be concerned about? D's is 6, he hadn't had a drink in 12 hrs as he was sleeping and he does sweat a lot at night. If I test again after he's had a normal amount of water and it returns to normal levels does it mean its nothing to worry about?
