1. What is an ACR Calculator?

Definition: An ACR calculator determines the albumin-to-creatinine ratio in urine, a key indicator of kidney function.

Purpose: This tool screens for kidney diseases by detecting elevated protein levels (albuminuria) in the urine.

2. How Does the Calculator Work?

The calculator computes the ratio using this formula:

Explanation: It converts albumin to mg/dL and creatinine to g/dL, then calculates the ratio in mg/g.

3. Importance of ACR Calculation

Details: ACR is a critical test for early detection of chronic kidney disease (CKD). Elevated levels may indicate kidney damage.

4. Using the Calculator

Tips: Input albumin (mg/dL, mg/L) and creatinine (mg/dL, mmol/L) values. Results show the ACR, converted units, and CKD stage.

Frequently Asked Questions (FAQ)

Q: What is a normal ACR value?
A: An ACR less than 30 mg/g is normal (A1). Values between 30-300 mg/g indicate moderate albuminuria (A2), and above 300 mg/g indicate severe albuminuria (A3).

Q: Why is my ACR undefined?
A: If creatinine is 0, the ratio cannot be calculated due to division by zero.

Q: Can this calculator diagnose kidney disease?
A: No, it’s for informational purposes only. Consult a doctor for a diagnosis.

Q: How often should I check my ACR?
A: People at risk (e.g., with diabetes or hypertension) should check regularly as advised by their healthcare provider.

Q: Are the conversion factors exact?
A: Conversions (e.g., 1 mmol/L = 11.31 mg/dL for creatinine) are approximate and based on standard values.
