Overview of prealbumin blood test

A prealbumin blood test measures the levels of prealbumin in your blood. Prealbumin is a protein that is complete in the liver. Prealbumin helps transport thyroid hormones and vitamin A through the bloodstream. It also helps control how your body uses energy. If your prealbumin levels are inferior to normal, it may be a sign of malnutrition. Malnutrition is a condition in which your body does not get the calories, vitamins, and/or minerals necessary for good health.

Other names:

  • Thyroxine-binding prealbumin
  • Transthyretin test
  • Transthyretin

Why is a prealbumin blood test done?

Prealbumin is a protein made by the liver. Your body uses it to make other proteins. If your doctor suspects that you are not getting enough protein, they may order this test for several reasons:

  • If you are elderly, they may want to know if you are getting enough nutrients from your diet.
  • In the case of a young child, a doctor can use this test to see if he is malnourished.
  • If you plan to have surgery in a hospital, your doctor may order this test to see what kind of nutritional support you will need during treatment.
  • Lastly, your doctor might do a prealbumin blood test if you have an eating disorder, to see how much protein you’ve lost.
  • If you are taking any medications, including over-the-counter ones, or if you are pregnant, you should notify your doctor before the test. All of these things can affect your test results.

What do the prealbumin blood test results mean?

Test results can vary based on your age, gender, medical history, the method used for the test, and other things. Your test consequences may not mean you have a problem. Ask your healthcare provider what your test results mean to you. Low prealbumin scores mean you likely need a nutritional evaluation. Low prealbumin scores can also be a sign of liver disease, inflammation, or tissue death (tissue necrosis). High prealbumin scores can be a sign of long-term (chronic) kidney disease, steroid use, or alcoholism.
