I am sure that the job role varies a little based on the type of company you work for. As for me, I work for a SP. I would like to give you some insight into what I do as a Network Engineer in my company, how Cisco certs helped me, how the job helped me with certs, and how it expanded my vision.

Creatinine is a natural product of muscle breakdown that occurs at a low level in the body. Both BUN and creatinine are filtered by the kidney and excreted in urine. For this reason, BUN and creatinine are used together to measure kidney function. If kidney function begins to decline, BUN and creatinine rise. A normal creatinine depends on muscle mass and age. In general, a normal creatine is 0.5 to 1.2 milligrams per deciliter (mg/dL). A normal BUN is 7 to 20 mg/dL. Remember that different laboratories use different testing equipment, and may have slightly different ranges for normal.
Blood Urea Nitrogen (BUN): Urea nitrogen is a normal waste product in your blood that comes from the breakdown of protein from the foods you eat and from your body metabolism.

Serum Creatinine: Creatinine is a waste product in your blood that comes from muscle activity.
