Albumin – biochemical blood test0162
Albumin is the most abundant plasma protein (about 60% of total proteins), produced in the liver. The molecular weight of albumin is approximately 66 kDa. It performs important functions: transport of fatty acids, hormones, and drugs, maintenance of oncotic pressure, buffering, and antioxidant activity. Measuring albumin levels helps assess the condition of the liver, kidneys, cardiovascular system, and overall protein balance in the body.
PHOT (photometry) – quantitative determination of albumin in blood serum.
- Assessment of liver and kidney function
- Edema, especially systemic
- Nutritional disorders (malnutrition, anorexia, bulimia)
- Presence of neoplasms
- Burns
- Cardiovascular diseases
Blood sampling in the morning on an empty stomach or 4 hours after eating. Drinking plain still water is allowed. Do not smoke for 30 minutes before the test. For children under 1 year – refrain from food for 30-40 minutes before the test; for children 1-5 years – 2-3 hours. It is important to avoid physical and emotional stress for 30 minutes before blood collection.
Decreased albumin levels may indicate hepatitis, liver cirrhosis, nephrotic syndrome, chronic inflammatory processes, malnutrition, and other pathologies. Increased levels may occur with dehydration or burns. Albumin level is an important marker for diagnosis and monitoring of the patient’s condition.
