This page helps you to understand blood test results for Albumin and gives you the reference range to determine if your lab test results mean that you have high albumin, low albumin or normal albumin levels.
We outline the risk factors associated with raised and low Albumin levels.
Reference Ranges for Albumin:
|US Conventional Units||g/dl||35-50||< 35 or > 50|
|Standard International Units||g/l||3.5-5||<3.5 or >5.0|
What is Albumin
Albumin is one of several proteins made in the liver, and is one of two main proteins in your blood, the other being Globulin. Since albumin can be low in many different diseases and disorders, it may be used in a variety of settings to help diagnose disease, to monitor changes in health status with treatment or with disease progression, and as a screen that may indicate the need for other kinds of testing .
An albumin test may be ordered as part of a liver panel to evaluate liver function OR as part of a renal panel to evaluate kidney function. Albumin may also be ordered to evaluate a person’s nutritional status .
Function of Albumin
Albumin keeps fluid from leaking out of blood vessels, nourishes tissues, and transports hormones, vitamins, and substances like calcium throughout the body .
Risk factors associated with Albumin
Your doctor will interpret your result for each biomarker in the context of the overall test and determine if your result warrants further investigation.
Low levels of Albumin in the Blood (hypoalbumenia) can be a sign of
- Liver damage or disease
- Renal (kidney) dysfunction
- Certain heart conditions
- Problems with your stomach – including inflammatory bowel disease can cause hypoalbuminemia
- Poor nutrition – Lack of protein in the diet 
Notable variations by Demographic Group
Low levels of albumin are more often seen in elderly patients .
