You may be able to find your test results on your laboratory’s website or patient portal. However, you are currently at Lab Tests Online. You may have been directed here by your lab’s website in order to provide you with background information about the test(s) you had performed. You will need to return to your lab’s website or portal, or contact your healthcare practitioner in order to obtain your test results.
Lab Tests Online is an award-winning patient education website offering information on laboratory tests. The content on the site, which has been reviewed by laboratory scientists and other medical professionals, provides general explanations of what results might mean for each test listed on the site, such as what a high or low value might suggest to your healthcare practitioner about your health or medical condition.
The reference ranges for your tests can be found on your laboratory report. They are typically found to the right of your results.
If you do not have your lab report, consult your healthcare provider or the laboratory that performed the test(s) to obtain the reference range.

Laboratory test results are not meaningful by themselves. Their meaning comes from comparison to reference ranges. Reference ranges are the values expected for a healthy person. They are sometimes called “normal” values. By comparing your test results with reference values, you and your healthcare provider can see if any of your test results fall outside the range of expected values. Values that are outside expected ranges can provide clues to help identify possible conditions or diseases.
While accuracy of laboratory testing has significantly evolved over the past few decades, some lab-to-lab variability can occur due to differences in testing equipment, chemical reagents, and techniques. This is a reason why so few reference ranges are provided on this site. It is important to know that you must use the range supplied by the laboratory that performed your test to evaluate whether your results are “within normal limits.”

Albumin is a protein made by the liver. It makes up about 60% of the total protein in the blood and plays many roles. This test measures the level of albumin in the blood.
Albumin keeps fluid from leaking out of blood vessels, nourishes tissues, and transports hormones, vitamins, drugs, and substances like calcium throughout the body. Levels of albumin may decrease, to a greater or lesser degree, when conditions interfere with its production by the liver, increase protein breakdown, increase protein loss via the kidneys, and/or expand the volume of plasma, the liquid portion of blood (diluting the blood).
Two important causes of low blood albumin include:
An albumin test may be used, along with other tests included in panels such as a comprehensive metabolic panel (CMP), to help evaluate your overall health status. These tests may also be used to help diagnose diseases and to monitor conditions or treatments. Albumin levels can be low in many different diseases and disorders. Abnormal results may indicate the need further testing.
Additionally, an albumin test may be ordered as part of a liver panel to evaluate liver function or with a creatinine, blood urea nitrogen (BUN), or renal panel to evaluate kidney function. Albumin may also be ordered to evaluate a person’s nutritional status.
An albumin test is frequently ordered as part of a panel of tests when you have a routine health exam.
This test may be ordered when you have signs and symptoms of nephrotic syndrome, such as:
A healthcare practitioner may also order an albumin test to check or monitor your nutritional status. However, since albumin levels respond to a variety of conditions in addition to malnutrition, a decrease in albumin needs to be evaluated carefully.
A low albumin level may be an indication that further investigation may be warranted. A low albumin may reflect a temporary condition that will resolve itself or may suggest an acute or chronic condition that requires treatment.
Levels of albumin may decrease, to a greater or lesser degree, when conditions interfere with its production, increase protein breakdown, increase protein loss, and/or expand plasma volume (diluting the blood). Depending on your medical history, signs and symptoms, and physical exam, additional testing may be done to investigate a low result.
A low albumin can suggest liver disease. Liver enzyme tests or a liver panel may be ordered to determine exactly which type of liver disease may be present. A person may, however, have normal or near normal albumin levels with liver disease until the condition has reached an advanced stage. For example, in people with cirrhosis, albumin is typically (but not always) low whereas in most chronic liver diseases that have not progressed to cirrhosis, albumin is usually normal.
Low albumin levels can reflect kidney diseases in which the kidneys cannot prevent albumin from leaking from the blood into the urine and being lost. In this case, the amount of albumin or protein in the urine also may be measured (see Urine Albumin) or tests for creatinine and BUN or a renal panel may be ordered.
Low albumin levels can also be seen in inflammation, shock, and malnutrition. They may be seen with conditions in which the body does not properly absorb and digest protein, such as Crohn disease or celiac disease, or in which large volumes of protein are lost from the intestines.
A low albumin may also be seen in several other conditions, such as:
High albumin levels can be seen with dehydration, although the test is not typically used to monitor or detect this condition.
Individuals who have chronic liver disease and kidney disorders are at highest risk for developing abnormal albumin levels. In addition, individuals whose gastrointestinal tract doesn’t absorb nutrients properly and individuals who have prolonged diarrhea can develop abnormal albumin levels.
Not for blood albumin; you can test for high albumin levels in urine with a dipstick purchased in a drug store.
Although the names are similar, albumin and prealbumin are completely different molecules. They are both proteins made by the liver, however, and both have been used historically to evaluate nutritional status. Serum/plasma (or blood) albumin is now more often used to screen for and help diagnose liver or kidney disease and is tested on a blood sample. The urine albumin test (in the past, called a microalbumin test) detects and measures albumin in the urine as an early indicator of kidney damage.
Certain drugs increase albumin in the blood, including anabolic steroids, androgens, growth hormones, and insulin.
If someone is receiving large amounts of intravenous fluids, the results of this test may be inaccurate.
