My mom is 52 and have hyper tension and diabetese. a recent lab test indicates that her creatinine content in blood is 2.1 what does that mean?

Renal insufficiency: People with hypertension and diabetes may develop renal disease if their blood pressure and diabetes are not controlled , an elevated creatinine level may be a sign of renal insufficiency and if this continues to worsen she will eventually need dialysis.

Creatinine of 2.1: Your mother's creatinine level means she has some stage of chronic kidney disease (ckd). To find out what stage she is in, you need to go to a nephrologist to have a 24 hour urine for creatinine clearance and protein done, along with having some blood taken. The results will indicate her glomerular filtration rate, which will give the stage of CKD she has.

Kidney Functions: Creatinine blood test if elevated as it is in your mom's case means that her kidney has been affected by Diabetes or there may be other explanation for it like dehydration.It needs to be checked again and it is persistently high that means the kidneys are being affected due to Diabetese and need to be monitored regularly
