Albumin is used as a marker for which of the following?

• A. Kidney or Liver Disease
• B. Heart Disease
• C. Lung Disease
• D. Skin Disease

Answer: (A)

Albumin reflects how well the liver is producing proteins and whether protein is being lost by the kidneys. Since albumin is made by the liver, a diseased liver often can’t synthesize enough, leading to low levels. At the same time, the kidneys can leak protein into the urine in conditions like nephrotic syndrome, which also lowers serum albumin. Because both decreased production by the liver and increased loss by the kidneys reduce albumin, low albumin serves as a useful marker of kidney or liver disease. It isn’t a primary indicator for heart, lung, or skin diseases, which involve different markers and processes.
