I had a health screening this week. i had a creatinine level of 1.24 and egfr of 48. what does this mean? i'm 55 and female. thanks!

Low kidney function: You have decreased renal (kidney) function. You should get seen by your primary doctor to find out the cause. Possible causes are: chronic high blood pressure, undiagnosed diabetes, chronic nsaid's (e.g. Ibuprofen use..), polycystic kidneys, lupus, bladder/kidney obstruction, artery blockage (stenosis) etc...

Creatinine of 1.24: From the results of your estimated gfr, 48 ml/min, you have chronic kidney disease. For an actual gfr, you need to have a 24 hour urine collection, along with some blood work to see if you have any disease of the kidney. Your physician can order this and/or send you to a nephrologist for an evaluation. You have hypertension and that may have caused you to have chronic kidney disease. Good luck.
