Which test measures the amount of albumin in the blood?

• A. Audiometry
• B. Albumin test
• C. Amniocentesis
• D. Bilirubin

Answer: (B)

Albumin is the main protein circulating in blood plasma, produced by the liver, and it helps maintain blood volume and transport substances. The albumin test directly measures how much albumin is present in the blood, making it useful for assessing liver function, kidney protein loss, nutritional status, and inflammation. It’s performed with a blood sample. The other tests check different things: audiometry tests hearing, amniocentesis collects amniotic fluid for fetal testing, and bilirubin testing gauges bilirubin levels related to jaundice and liver function. Since this test specifically quantifies albumin in the blood, it is the correct choice.
