2 y.o female has normal bun(8mg/dl)&creatinine(0.23mg/dl) but bun/creatinine ratio is abnormal at 35. why is this? fasting blood glucose is also 134.

Bun and creatinine: Do not worry about ratio of bun/cr. Bun is affected by many factors, hydration status, protein intake, muscle mass, whether on any hormone supplement. In this case, the creatine is quite low which is not necessarily a problem. Glucose can normally be higher in young children, so not a problem. A pediatrician or endocrinologist can tell you more if fasting glucose of 134 in a 2 yr old is a problem?
