Albumin/creatinine ratio (ACR) in a spot urine sample
The test determines the albumin-to-creatinine ratio in a spot urine sample - an important marker of early kidney damage, especially in patients with diabetes mellitus or hypertension. Used to detect microalbuminuria and assess the risk of kidney disease progression.
Mechanism of deviations: an elevated albumin/creatinine ratio in urine indicates damage to kidney filtration function and the onset of protein excretion.
Who should be tested:
- Persons with diabetes mellitus or hypertension
- With chronic kidney diseases
- For early nephropathy diagnosis
- To monitor therapy efficacy and prevent complications
Biomateri: Spot urine sample
- Collect a spot urine sample in a clean container
- Exclude intense physical activity and stress 24 hours before
- Avoid overexertion before collection
Medications: if taking drugs affecting kidneys or protein metabolism - inform the physician
- Suspected early stages of kidney damage
- Monitoring of patients with diabetes mellitus, hypertension, or cardiovascular diseases
- Therapy monitoring in chronic kidney diseases
- Changes in diuresis, edema, or elevated blood pressure
Normal - albumin/creatinine ratio within reference values
Elevated - indicates microalbuminuria, requires physician consultation for kidney function assessment and therapy adjustment
Consult a general practitioner or nephrologist with test deviations.
Self-treatment is not recommended!
