Those looking for a creatinine blood test should go to a local laboratory facility to have their blood drawn, notes Healthline. As part of the blood test procedure, the technician locates a vein in the arm and inserts a needle into the vein to collect a blood sample.
Creatinine blood tests are usually not painful, but a slight prick or stinging sensation may be noticed when the needle is inserted, states MedlinePlus. Doctors typically order creatinine blood tests to monitor kidney function. Creatinine levels in the blood normally range from 0.7 to 1.3 milligrams per deciliter in men and 0.6 to 1.1 milligrams per deciliter in women.
