Albumin is a protein found in your blood plasma. A blood test measuring albumin levels helps assess your liver and kidney function. Low albumin levels might signal kidney disease, liver disease, inflammation, or infections. Conversely, high albumin levels often indicate dehydration or severe diarrhea.
What does an albumin blood test measure?
An albumin blood test specifically measures the amount of albumin protein present in the clear liquid part of your blood (serum). As the liver produces albumin, abnormal levels can indicate problems with liver function. Additionally, because albumin plays a crucial role in transporting substances, including hormones and medications, and its presence in urine (albuminuria) can suggest kidney damage, the test also provides insights into kidney health. The test can be part of a routine checkup or used to investigate specific symptoms.
What do the results mean?
- Low Albumin Levels: Could indicate:
- Kidney disease
- Liver disease
- Inflammation
- Infections
- Malnutrition
- Gastrointestinal disorders
- High Albumin Levels: Often suggests:
- Dehydration
- Severe diarrhea
The test helps evaluate overall protein levels and might be used to monitor conditions affecting the liver and kidneys, aiding in the diagnosis and management of various health issues. A healthcare professional will interpret the results in conjunction with other medical information to reach a diagnosis and develop a suitable treatment plan. Further investigation, such as additional tests, may be needed.
Where is albumin found?
Albumin is primarily found in the blood plasma (the liquid part of your blood). It's also measurable in urine. A healthy kidney effectively prevents albumin from passing into urine.
