Albumin is the most abundant protein in blood plasma, produced by the liver.

It plays a key role in maintaining oncotic pressure and transporting hormones, drugs, and other substances.

Clinical uses include:

Assessing liver function (low albumin suggests impaired synthesis).

Evaluating nutritional status and protein deficiency.

Detecting kidney disease (albumin loss in urine).

Monitoring patients with chronic illness, inflammation, or edema.

The test is performed using a blood sample.

Analyte: Serum albumin concentration.

Normal Range: ~3.5 – 5.0 g/dL (varies slightly by lab).

Abnormal Findings:

Low albumin (hypoalbuminemia): Suggests liver disease, malnutrition, nephrotic syndrome, chronic inflammation, or protein loss.

High albumin (rare): Usually due to dehydration or hemoconcentration.

Clinical Use:

Provides insight into liver synthetic function.

Helps evaluate nutritional and metabolic status.

Supports diagnosis and monitoring of renal and hepatic disorders.
