Albumin-to-Creatinine Ratio (ACR) Urine Testing
Why it’s important, and how you can start testing in your office or clinic

Albumin-to-Creatinine Ratio (ACR) Urine Testing
Contact Us

Albuminuria is the presence of albumin in the urine and a marker of kidney damage.

It is normal for individuals to excrete very small amounts of protein in the urine, but the albumin-to-creatinine ratio (ACR) is the first method of preference to detect elevated protein, measuring urinary ACR in a spot urine sample. ACR is calculated by dividing albumin concentration in milligrams by creatinine concentration in grams.1


1 out of 3 people is at risk of kidney disease.
If you have diabetes, you’re at higher risk for kidney disease.
If you are over 60, you’re at higher risk for kidney disease.
If you have high blood pressure, you’re at higher risk for kidney disease.
You could help save your kidneys with a simple urine test.

ACR Testing Solutions

Proven Performance in Urinalysis — from the Point of Care to the Central Lab

Whether you are a physician in an office or a laboratorian in a central lab, screening for kidney disease is at your fingertips. Siemens CLINITEK® Microalbumin 2 Reagent Strips detect albumin and creatinine levels in urine, providing an albumin-to-creatinine ratio and allowing treatment to begin sooner.

  • Detect kidney disease at the earliest stages—albumin sensitivity as low as 10 mg/L
  • Ratios utilizing creatinine account for the variability of albumin results due to urine concentration
  • Provide results in one minute
  • Reduce transcription errors and wait time—when used in combination with CLINITEK Status® family of analyzers, results can be electronically managed or printed

Combining the CLINITEK Novus® Analyzer and the Atellica® UAS 800 Analyzer* into one completely automated unit, the Atellica 1500 Automated Urinalysis System* sets the new standard for accuracy and efficiency. It is a truly digital automated urinalysis system that lets you manage more samples with less staff in shorter time, while never compromising on high-quality results.

Use CLINITEK Novus PRO 12 cassettes* for early detection of kidney disease. They provide microalbuminuria testing with albumin-to-creatinine (A:C, ACR) ratio results.

NKF Alliance

Siemens Healthineers and the National Kidney Foundation (NKF) have formed a strategic alliance focusing on education, awareness, and screening for kidney disease in high-risk individuals. This important collaboration leverages the latest testing recommendations from the NKF to improve detection among those at risk for kidney disease.

These new recommendations call on healthcare professionals to screen patients in high-risk groups by adding simple urine albumin tests to their patients' annual physical exams.

National Kidney Foundation Strategic Alliance for Education and Screening

Siemens Healthineers supports the goals of the National Kidney Foundation to increase awareness, prevention, and treatment of chronic kidney disease (CKD). Through early intervention and education, the alliance encourages timely testing for at-risk individuals by primary care practitioners.

Your Kidneys And You

Go from "zero" to "kidney consciousness" in less than 3 minutes with the NKF’s “Your Kidneys and You” video! Most people don't know how important their kidneys are to their health. If caught early, kidney disease can be slowed or even stopped. Watch and share this video to help raise awareness about kidney health.

Learn about Kidney Disease

Kidney disease refers to any disease, disorder, or condition that affects the kidneys. Siemens Healthineers partners with healthcare providers to improve the patient experience over a lifetime of the kidney healthcare continuum.

Help Raise Kidney Health Awareness

Whether as a patient or when caring for a loved one, being informed about kidney disease is a powerful way to improve the patient experience. It can provide comfort and enable confidence to make more-informed care decisions.
