Is a GFR of 120 good?

According to the National Kidney Foundation, normal results range from 90 to 120 mL/min/1.73 m2. Older people will have lower than normal GFR levels, because GFR decreases with age.

Can eGFR be wrong?

“Near the border of 60 mL/min/1.73 m2 creatinine-based eGFR can be inaccurate. More than half of patients with eGFR less than 60 have an eGFR of 45 to 60, and in that group there are a lot of false positives, meaning the eGFR based on creatinine says they have CKD, but their kidney function may be normal.

What can cause a false GFR?

High Creatinine Levels on Your Blood Test? Taking These 4 Drugs Can Cause a False Alarm

  • 1) Sulfamethoxazole / trimethoprim (Bactrim / Septra)
  • 2) Acid blockers — cimetidine (Tagamet) & ranitidine (Zantac)
  • 3) Cephalosporin antibiotics.
  • 4) Fenofibrate (Tricor)

What is normal creatinine level in UMOL L?

Normal Results A normal result is 0.7 to 1.3 mg/dL (61.9 to 114.9 µmol/L) for men and 0.6 to 1.1 mg/dL (53 to 97.2 µmol/L) for women. Women often have a lower creatinine level than men. This is because women often have less muscle mass than men.

What is a bad kidney function number?

A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.

Should I worry if my GFR is 46?

What are normal serum creatinine ranges?

Normal serum creatinine ranges are: Serum creatinine ranges are lower for women because women have less muscle mass and, thus, a lower rate of creatinine formation and excretion. Normal blood creatinine levels also vary by race. For non-Hispanic blacks, the average blood creatinine is 1.25 mg/dL in men and 1.01 mg/dL in women.

How do you measure creatinine clearance?

It is usually measured using both a blood test and a urine test. The creatinine clearance can also be estimated from a mathematical formula that will use the blood levels of creatinine along with other factors (such as your age, race, and gender). Creatinine clearance testing determines your overall glomerular…

What is the difference between GFR and creatinine clearance?

The GFR is the main number used by your provider to determine how well your kidneys are working. The creatinine clearance test is not used very often any more. It has largely been replaced by the estimated GFR (eGFR) equations using creatinine levels in the blood — which means a 24-hour urine collection is not needed.

Do I need a 24-hour urine collection to calculate GFR?

It has largely been replaced by the estimated GFR (eGFR) equations using creatinine levels in the blood — which means a 24-hour urine collection is not needed. Cleveland Clinic is a non-profit academic medical center.
