Yes, these lab results are likely a result of your vigorous exercise just prior to the test. Your vigorous exercise likely lead to some dehydration which caused a decrease in your kidney function temporarily. If you are otherwise healthy with no other medical problems, this is likely nothing to worry about. You should just have the lab repeated on a day where you have not had any vigorous exercise over the past 24 hours and when you are well hydrated. Hope this helps and let me know if you have questions.
I am a urologist who has been in practice for 15 years. I deal with patients kidneys and their kidney function and the structural problems with their kidneys on a daily basis. I see these type of lab results every day.
You're very welcome. I wish you the very best. Please don't forget to leave me a rating. Thanks!
