I'm a medical doctor. One thing your doctor overlooked is the "e" in eGFR. It stands for estimated. As in they don't have any idea what is your actual glomerular filtration rate, but the computer knows that fat, diabetic, hypertensive, out-of-shape humans with those values might have one in the range of what is reported for you if they had early kidney disease. eGFR is nothing more than a red flag to catch the attention of people who don't know what the creatinine value means. Then - notice it's adjusted for race? As though every white person has the same biochemistry as every other white person, and every black person has the same biochemistry as every other black person, and they're always different?
It isn't hard to measure glomerular filtration rate. It takes time, injecting you with a non-metabolized chemical called inulin, and measuring your pee for a while. Somebody has to risk getting your pee on their hands when they open the jug. This is too much work for the lazy medical system, primarily concerned with getting more money for less work. I would venture if they actually measured your GFR it would be normal, since you're healthy. The commonest things causing early renal failure in your age group are high blood pressure; meth or cocaine use; kidney diseases you were born with; diabetes; and overuse of non-steroidal antiinflammatory agents like ibuprofen and naproxyn. Absent one of those I think the chance of you having kidney disease is close to zero.
But logic may not prevail. You could ask for a real GFR measurement, rather than allowing your future to be decided by a guess.
Otherwise, time to look at reality as you try to adjust to an insane world: Is it more important to you to take creatine for a month, or to stay in the Navy?
And you've learned a valuable lesson about medical testing, and medicine in general: Nobody cares but you. Follow up, follow up, follow up right away. Call them. Bug them until you get an answer. You might have been able to head this off in February.
Whenever they're doing kidney tests, drink so much water you have to stop and pee on the way to the lab. Make sure your pee is colorless. Don't put tap water in your pee collection cup. They few bright ones figure that out.
