Which diagnostic studies would the health care provider prescribe to determine loss of kidney function secondary to fibrosis from significant anatomic abnormalities or recurrent upper urinary tract infections

by blood tests such as, for example, Glomerular filtration rate (GFR)

Explanation:

Diagnosis of kidney problems can be made by different types of blood tests including, among others, Glomerular filtration rate (GFR) and blood urea nitrogen test (BUN). These tests are able to measure the accumulation of waste products in the blood. GFR is one of the best techniques to measure kidney function by determining levels of an endogenous blood biomarker, for example, serum creatinine levels. Creatinine levels can be higher than normal due to blockage of the urinary tract and it can occur during kidney infections such as pyelonephritis. GFR test measures how much blood passes through the glomeruli -a network of small capillaries that filter blood in the kidneys- in each minute. GFR values are low at birth but increase with age.

answer:

it could come from a variety of sources.

explanation:

..although it was most likely developed through zoonotic transmission, where an infectious disease which usually afflicts when animals jump to humans.
