Many health professionals work together to diagnose AKI and determine the severity. Medical lab technologists can test the presence of wastes in the blood, indicative of an impaired elimination from the renal system. Similarly, they can test for the presence of useful nutrients in the urine, indicative of impaired reabsorption at the nephron level. Sonographers can give real-time imaging of blood flow to the kidney and of the kidney itself. This is helpful for prerenal causes as sonographers can use the ‘doppler’ to measure blood flow to the kidney and for post-rental causes as an obstruction can be visualized.
