Albumin is an important protein found in the blood. The protein can leak out of the blood into the urine in case of impaired kidney function and kidney disease, which then leads to a drop in the albumin value. The albumin concentration is checked above all to rule out reduced kidney function or kidney disease and also in case of suspicion of damage or disease in the liver. The albumin concentration is an important part of the body's fluid balance status and gives an idea of the hydration and colloid osmotic pressure.
The role of albumin in hormone transport
Albumin also functions as a transport protein for many hormones, including sex hormones such as testosterone and estradiol, as well as thyroid hormones. This means that changes in albumin levels can affect the hormonal balance in the body. It is therefore important to consider albumin levels when interpreting hormone tests, as a decreased albumin concentration can lead to an increased proportion of free, biologically active hormone in the blood.
Albumin and the body's fluid balance
Albumin plays a key role in the body's fluid balance by retaining fluid in the blood vessels. When albumin levels are low, fluid can leak into the tissues and cause swelling (edema), which can be seen in conditions such as liver disease or protein deficiency. The test may therefore be relevant for evaluating fluid balance and nutritional status.
Who should test their albumin value?
- People with suspected kidney or liver disease.
- Diabetics who want to monitor their kidney function.
- People with symptoms of fluid retention or edema.
- Individuals who want to evaluate their nutritional status and protein balance.
- Those who are undergoing hormonal tests and want to get a more complete picture of their hormone balance.
A blood test for P-Albumin provides important information about kidney and liver health, the body's fluid balance and hormone transport. The test is relevant for those who want to gain insight into your kidneys and whether you may be affected by impaired kidney function.
