My son has .66 creatinine level and black stools. Bun is normal. He is on a high protein diel that includes filets and he eats a lot of veggies, Virtually eats no carbs, He also has a stable
stage II astrocytoma. He is seeing GI doctor on Friday, so besides a finger wave, urine sample, is there anything else he should ask the GI to do I told him the black stools and low creatinine would signal an endoscopy.to me. He hasn't had one in 5 years. He is under a lot of stress with the astrocytoma and his depressive spouse
