7 day old nephew has a .11mg/dl serum creatinine. is it normal? he received high dose of amikacin by mistake 3 days before the blood test. thanks.

Cr .11: is it 0 .11 or 1.1? 0.11 seems low but that usually is not a problem, 1.1 may be minimally high which coudl be due to dehydration so would recheck it in a week after drinking about 2 glasses water to see the trend and could also dip the urine for protein. . But most important call the lab where it was done and ask for their reference values as every lab differs a it in what is normal
